You are listening to music or watching a video and you notice something is off — the sound feels lopsided. You run a quick test and confirm it: only one speaker is producing audio. This is one of the most common audio complaints, and in most cases it is completely fixable without buying new hardware.

Use the Left Right Stereo Test above to confirm exactly which channel has failed before trying these fixes.

Cause 1: Audio Balance Is Set Off-Center

This is the most common reason — and the easiest fix. Every operating system has a stereo balance control that lets you shift audio volume between left and right. If this is accidentally set to one side, the other speaker will be silent or very quiet even though nothing is broken.

Cause 2: The Headphone or Speaker Plug Is Not Fully Inserted

A 3.5mm audio plug that is not fully inserted will only make contact with the first ring of the connector — which carries only one channel. This makes it sound like one side is dead when the plug is simply loose. Push the plug in firmly until you feel it click into place. This is especially common with laptop headphone jacks where the port is recessed.

Cause 3: A Damaged Cable Near the Plug

Audio cables most commonly break at the point where they enter the plug or the headphone earcup. The insulation outside looks fine but the wire inside has snapped. To test this, play audio and slowly wiggle the cable near the plug. If sound cuts in and out, the cable is damaged at that point.

For headphones with a removable cable, simply buy a replacement cable. For permanently wired headphones, a local electronics shop can often resolder the connection for a small fee.

Cause 4: A Dirty or Corroded Audio Jack

Lint, dust, and moisture build up inside the headphone jack over time. This debris creates a poor electrical connection, causing one channel to drop out. To clean the jack, blow compressed air into the port or carefully insert a dry cotton swab to remove lint. Do not use liquids.

Cause 5: Outdated or Corrupted Audio Drivers (Windows PC)

On Windows, a corrupted or outdated audio driver can cause one channel to stop working even though the hardware is fine. To fix this:

1. Press Windows + X and click Device Manager
2. Expand Sound, video and game controllers
3. Right-click your audio device and choose Update driver
4. Select Search automatically for drivers
5. Restart your computer after the update

Cause 6: The Speaker Itself Has a Blown Driver

If all the software fixes above do not work and the problem persists on multiple devices, the speaker driver may be physically blown. This usually happens after prolonged use at high volumes. Test your speakers or headphones on a different device — phone, tablet, or another computer. If the same channel is silent on every device, the speaker hardware needs to be replaced.

A single dead earbud is frustrating — but before you throw your headphones away or spend money on a replacement, it is worth spending two minutes diagnosing the actual cause. In many cases, the fix is completely free.

Start by using the Headphone Channel Test to confirm which side has failed and whether the problem is the headphone or the device.

Step 1: Test on a Different Device First

Plug your earbuds into a different device — a phone, tablet, or another computer. Run the headphone test again. This single step tells you everything:

• Same earbud dead on the new device: The headphone or cable is faulty. Continue to Step 2.
• Both earbuds work on the new device: The problem is in your original device's settings or port. Check the audio balance setting (see Article 1) and clean the headphone jack.

Step 2: Check the Audio Balance on Your Device

Before assuming hardware damage, always check the stereo balance setting on your device. On iPhone, go to Settings → Accessibility → Audio & Visual → Balance. On Android, Settings → Accessibility → Hearing → Balance. On Windows, check Sound Settings → Device Properties → Balance. If balance is fully shifted to one side, reset it to center and test again.

Step 3: Inspect the Cable for Damage

While playing audio through the working earbud, slowly and gently bend the cable along its entire length. Pay special attention to three points: where the cable enters the plug, where it splits into two earbuds, and where it enters each earcup. If the dead earbud crackles or comes back to life at any point, you have found the break location.

Step 4: Clean the Headphone Jack

Lint and dust inside the audio port of your phone or laptop can prevent full electrical contact, making one channel fail intermittently. Use a toothpick or dry cotton swab to carefully remove debris from the port. You can also briefly blow into the port. Do not use any liquids.

Step 5: Check for Wax Buildup (In-Ear Earbuds)

In-ear earbuds have tiny mesh screens that can become blocked with earwax over months of use. A blocked screen dramatically reduces volume from that earbud and can sound like total failure. Remove the silicone ear tip, hold the earbud mesh-side down, and gently tap it against your palm. For stubborn blockages, use a dry soft-bristle toothbrush to gently clean the mesh.

Step 6: For Wireless Earbuds — Reset and Re-Pair

If you have wireless earbuds (like AirPods or similar), a software glitch can cause one earbud to stop working. Place both earbuds in the charging case, wait 30 seconds, then remove them and re-pair with your device. For AirPods specifically, press and hold the setup button on the back of the case until the light flashes amber, then white, and re-pair from your iPhone Bluetooth settings.

If your speakers or headphones sound louder on one side on a Windows PC, the most likely cause is that the stereo balance control has been shifted from its center position. This can happen accidentally — through a system update, a third-party audio app, or even by bumping a volume slider. The good news: fixing it takes under two minutes.

Before changing any settings, confirm the problem using the Left Right Stereo Test to see exactly which channel is quieter or silent.

Method 1: Fix Balance via Windows Sound Settings (Windows 10 and 11)

Method 2: Fix Balance via the Classic Sound Control Panel

Method 3: Check Third-Party Audio Software

Some PCs come with audio software pre-installed — such as Realtek Audio Console, Nahimic, DTS Sound Unbound, or Dolby Atmos. These apps have their own balance and equalizer settings that can override Windows settings. Open any of these apps that are installed on your PC and check for balance sliders. Reset any equalizer presets that may have shifted one channel.

Method 4: Update or Reinstall Your Audio Driver

A corrupted audio driver can cause persistent balance issues that survive system restarts. To update or reinstall the driver:

1. Press Windows + X and click Device Manager
2. Expand Sound, video and game controllers
3. Right-click your audio device (e.g. "Realtek High Definition Audio") and choose Uninstall device
4. Check the box that says Delete the driver software for this device
5. Restart your computer — Windows will automatically reinstall a fresh driver
6. After restart, test the audio balance again

Method 5: Check Accessibility Settings

Windows has an accessibility feature called Mono Audio that mixes both channels into one. While this does not cause imbalance directly, check that it is disabled if you are having stereo issues. Go to Settings → Ease of Access → Audio and make sure "Turn on mono audio" is set to Off.

Bluetooth audio that keeps cutting out, dropping, or stuttering is one of the most frustrating audio problems. The good news is that in most cases the problem is caused by interference, distance, or a simple software setting — not a broken device. These 7 fixes cover every common cause.

Fix 1: Move Closer to the Bluetooth Source

Bluetooth has a limited range — typically around 10 metres (33 feet) in open space. Walls, furniture, and other obstacles reduce this significantly. If you are moving around while listening, try staying within 5 metres of your phone or computer. If the cutting out stops when you move closer, distance or obstacles are your problem.

Fix 2: Remove Sources of Wireless Interference

Bluetooth operates on the 2.4GHz radio frequency — the same band used by Wi-Fi routers, microwave ovens, baby monitors, and many other wireless devices. When these devices are active nearby, they compete with your Bluetooth signal and cause dropouts.

Fix 3: Disconnect and Re-Pair the Device

A corrupted pairing profile can cause persistent dropout issues. Remove the device from your Bluetooth list completely and pair it fresh.

Fix 4: Update Your Bluetooth Driver (Windows)

On Windows PCs, an outdated Bluetooth driver is a very common cause of audio dropouts. Open Device Manager (Windows + X), expand "Bluetooth", right-click your Bluetooth adapter, and select "Update driver". Choose "Search automatically for drivers" and restart after the update.

Fix 5: Change the Bluetooth Audio Codec

Bluetooth uses audio codecs to compress and transmit sound. Some codecs are more stable than others. On Android, you can change the codec in Developer Options. Go to Settings → About Phone → tap "Build number" 7 times to enable Developer Options → go back to Settings → Developer Options → scroll to "Bluetooth Audio Codec" → try changing from AAC or aptX to SBC, which is the most stable codec even if it has slightly lower quality.

Fix 6: Charge Your Bluetooth Device

When wireless headphones or earbuds have low battery, their Bluetooth transmitter weakens — causing dropouts. Even if the battery indicator shows 20-30%, try fully charging the device and testing again. This is especially common with cheap earbuds where battery indicators are not accurate.

Fix 7: Reset Your Bluetooth Headphones to Factory Settings

Most Bluetooth headphones have a factory reset option that clears all pairing data and resets the firmware. Check your headphone manual for the specific button combination. After resetting, re-pair with your device. This fixes many persistent Bluetooth issues that survive regular disconnection.

In competitive gaming — especially FPS games like Call of Duty, Valorant, CS2, and Apex Legends — what you hear is just as important as what you see. Footsteps, reloads, and gunshots all have directional audio that tells you exactly where your enemy is. Getting your audio setup right can directly improve your performance.

Step 1: Choose the Right Headset Type

Not all headsets are equal for gaming. Here is what actually matters:

Step 2: Test Your Headset Stereo Balance First

Before adjusting any settings, verify that your headset has equal volume in both ears. An imbalanced headset will make directional audio feel "off" — you may think enemies are to the left when they are in front. Use the test below to verify your headset is perfectly balanced.

Step 3: Windows Audio Settings for Gaming

Step 4: Enable Virtual Surround Sound (Optional)

Windows Sonic and Dolby Atmos for Headphones are the two main virtual surround options on Windows. To enable Windows Sonic: right-click the speaker icon → Spatial sound → Windows Sonic for Headphones. This is free and works well for gaming. Dolby Atmos requires a paid subscription but offers more detailed spatial audio.

Step 5: In-Game Audio Settings

Step 6: Microphone Setup for Team Communication

Clear communication is as important as hearing enemies. In Windows Sound settings, select your headset microphone as the default recording device. Set the microphone level to around 80 — not 100, which causes clipping and distortion. Enable noise suppression if your game or communication software (Discord, TeamSpeak) offers it.

Step 7: Equalizer Settings for Competitive Gaming

If you use equalizer software like Equalizer APO or your headset's companion app, these EQ settings improve competitive audio:

A phone with no sound is very frustrating — but before spending money on a repair, work through these fixes. Most cases of sudden audio failure on smartphones have a simple software or settings cause that takes under 5 minutes to fix.

Fix 1: Check Silent Mode and Volume

This sounds obvious but it is the most common cause. On iPhone, check the physical Ring/Silent switch on the left side of the phone — if it shows orange, the phone is on silent. On Android, press the volume up button and make sure the Media volume is not at zero. Also check: Do Not Disturb mode can silence all sounds — swipe down the notification shade and check if DND is active.

Fix 2: Check If Audio Is Routed to a Connected Device

If Bluetooth headphones or a car audio system were recently connected, your phone may still be routing audio there even after you disconnected. On iPhone: Control Center → tap the AirPlay icon on the music player → select "iPhone". On Android: pull down the notification shade → tap the media output icon → select "Phone Speaker".

Fix 3: Clean the Speaker Grille

Phone speaker grilles collect lint, dust, and pocket debris over time. A partially blocked grille sounds muffled or very quiet. Hold the phone speaker-side down and gently tap the back. Then use a soft dry toothbrush to carefully brush across the grille — never blow directly into it as moisture causes corrosion. A can of compressed air from a distance of 10cm also works well.

Fix 4: Restart Your Phone

A full restart clears temporary software glitches that can cause the audio system to freeze. Power off completely (not just sleep), wait 30 seconds, then power back on. This fixes many sudden audio failures that appear after app crashes or system updates.

Fix 5: Check for Stuck Headphone Mode (iPhone)

iPhones can get stuck in headphone mode — the phone thinks headphones are plugged in and routes all audio there, making the speaker silent. To fix: plug in a wired headphone and unplug it slowly. If that does not work, try a different pair of headphones. You can also try inserting and removing a headphone plug several times to clean the contacts. On iPhone 7 and later (which use the Lightning port for audio), clean the Lightning port with a toothpick to remove lint.

Fix 6: Update iOS or Android

Audio bugs are sometimes introduced by software updates and then fixed in the next patch. On iPhone: Settings → General → Software Update. On Android: Settings → Software Update → Check for Updates. Always install the latest update if one is available.

Fix 7: Reset All Settings (iPhone) / Reset App Preferences (Android)

On iPhone: Settings → General → Transfer or Reset iPhone → Reset → Reset All Settings. This resets all system settings to default without deleting your data or apps. On Android: Settings → General Management → Reset → Reset App Preferences. Both of these fixes resolve audio routing issues caused by conflicting app or system settings.

Fix 8: Hardware Test

If none of the above works, there may be a hardware fault. On iPhone, go to Settings → Privacy → Microphone and test if any app can detect sound — this tests the microphone which shares circuits with the speaker. For a comprehensive hardware test, dial *#7353# on Samsung Android devices to open the built-in diagnostic menu and run the speaker test.

You do not need expensive measurement equipment to evaluate your speakers or headphones. These 5 tests use free tools and your own ears to identify common quality problems. Whether you just bought new speakers or want to check if your old ones are degrading, these tests give you clear, reliable results.

Test 1: Left Right Balance Test

The first and most important test. Both speakers should play at exactly equal volume. Sit or stand an equal distance from both speakers, close your eyes, and play a mono audio source (a single vocal track or spoken word). The voice should appear to come from exactly the center between the two speakers. If it pulls to one side, your balance is off or one speaker is louder.

Test 2: Frequency Response — Bass Test

Play music with deep bass content — electronic music, hip-hop, or film soundtracks work well. Good speakers reproduce bass that you can feel as well as hear. If bass sounds thin, weak, or completely absent, the speaker lacks low-frequency capability or the bass driver is damaged. For headphones, place them on your ears and the bass should feel present without being boomy or distorted.

Test 3: Distortion Test at High Volume

Gradually increase volume to 80% of maximum while playing music. Listen carefully for any crackling, buzzing, rattling, or "breaking up" of the sound. Clean speakers should get louder without distorting. Distortion at moderate or high volumes indicates a blown or damaged speaker cone. A rattle often means a loose component inside the speaker enclosure.

Test 4: Stereo Imaging and Channel Separation Test

Good stereo imaging means you can hear sounds placed at different positions across the room — some instruments to the left, some to the right, some in the center. Use the channel separation test below and listen for clean, distinct separation between the left and right channels with no sound bleeding through to the opposite side.

Test 5: High Frequency Clarity Test

Play a track with prominent cymbals, hi-hats, or acoustic guitar string plucks. High frequencies should sound clear, detailed, and slightly airy — not harsh, sibilant (overly "ssss" sounds), or absent. Missing high frequencies make music sound dull and muffled. Harsh highs suggest tweeter damage or a poor crossover network in the speaker.

Dirty headphones do not just look bad — they actually sound worse. Earwax, skin oils, and dust block the speaker mesh, reduce high-frequency output, and cause muffled or imbalanced sound. Regular cleaning also prevents ear infections and extends the lifespan of expensive headphones.

What You Need

Cleaning In-Ear Earbuds (AirPods, Earbuds)

Cleaning Over-Ear and On-Ear Headphones

Cleaning the Headphone Jack on Your Device

The headphone jack on your phone or laptop also accumulates lint and debris. Use a toothpick to carefully pull out compacted lint from the bottom of the port. Do not use metal objects. A quick burst of compressed air from 10cm away also works well. A clean port ensures full electrical contact and prevents one-channel audio issues.

How Often To Clean

For earbuds used daily: clean the mesh once a week and wipe the body after each use. For over-ear headphones: wipe the ear pads weekly and deep clean monthly. If you share headphones with others, clean them before and after each person uses them.

Audio drivers are the software that allows Windows to communicate with your sound card or audio chip. Outdated, corrupted, or incompatible drivers cause a wide range of problems including crackling sounds, no audio output, microphone not working, and stereo balance issues. Updating or reinstalling the audio driver fixes most of these problems.

Method 1: Update Through Device Manager

Method 2: Download Driver Directly from Manufacturer

Windows Update does not always find the latest driver. For the most up-to-date version, download directly from the manufacturer website. The most common audio chips and where to find their drivers:

Method 3: Uninstall and Reinstall the Driver (Best for Corruption)

If updating does not fix the problem, a full uninstall and reinstall often works when the driver file has become corrupted.

Method 4: Use Windows Update

Windows Update often includes audio driver updates bundled with system updates. Go to Settings → Windows Update → Check for updates → also click "Advanced options" → "Optional updates" — audio drivers sometimes appear here as optional updates.

After Updating — Test Your Audio

After installing new drivers, test both channels to make sure everything is working correctly. A fresh driver installation sometimes resets the balance or default device settings.

Crackling, buzzing, hissing, or popping audio is one of the most commonly reported audio problems. Unlike a completely silent speaker, audio interference is harder to diagnose because there are many possible causes. This guide goes through every common cause systematically so you can find and fix yours.

Cause 1: Loose or Damaged Audio Cable

The most common cause of crackling audio. A cable with a partially broken wire creates an intermittent electrical connection — you hear crackling when the wire makes and loses contact. Test by slowly wiggling the cable at the plug end and at each connection point while audio is playing. If the crackling changes, you have found the damaged section. Replace the cable.

Cause 2: Dirty or Worn Audio Jack

Oxidation, dirt, and bent connector pins inside the headphone jack cause poor electrical contact and crackling. Insert and remove the headphone plug 5-6 times slowly — this scrapes the contacts clean. You can also use a cotton swab lightly dampened with isopropyl alcohol to clean the inside of the port. Let it dry completely before plugging anything in.

Cause 3: Electrical Interference (Ground Loop Buzz)

A constant low-frequency buzz (50Hz or 60Hz hum) that is always present regardless of volume is a ground loop — an electrical interference problem. This happens when two audio devices connected together have a voltage difference in their ground connections. Common scenarios: speakers connected to a PC while both are plugged into different power outlets, or a guitar amp connected to a computer.

Cause 4: Outdated or Corrupted Audio Driver

Driver issues cause crackling that appears inconsistently and may only happen during certain audio playback. Update or reinstall your audio driver following the steps in our driver guide. Also try changing the audio format: right-click the speaker icon → Sound Settings → Device Properties → Additional Properties → Advanced → change the format from 16-bit to 24-bit or change the sample rate.

Cause 5: CPU Overload (DPC Latency)

When the computer processor is heavily loaded, audio processing can stutter — causing clicks and pops in the audio output. This is called DPC (Deferred Procedure Call) latency. Check if crackling occurs specifically when running demanding programs. To test: open Task Manager (Ctrl+Shift+Esc) and check CPU usage while audio crackles. If CPU is above 80%, close unnecessary programs or background tasks.

Cause 6: Wireless Interference (Bluetooth and Wi-Fi)

Wireless headphones and earbuds can crackle due to radio interference, low battery, or distance from the source device. For Bluetooth audio crackling specifically: move closer to the source, charge the device fully, disconnect and re-pair, and try changing the Bluetooth codec to SBC for maximum stability.

Cause 7: Blown or Damaged Speaker Cone

A physically damaged speaker cone crackles most prominently at certain frequencies or at high volumes. Play a range of music styles and listen for when the crackling is worst. If it crackles specifically on bass notes or at louder volumes, the woofer cone is damaged. If it crackles on high notes, the tweeter is damaged. Speaker replacement is required for physical damage.

Cause 8: Sample Rate Mismatch

When your audio device is set to a different sample rate than the audio content being played, the system must convert in real-time — this can cause crackling, especially on lower-powered computers.

Your microphone is not picking up audio — or people in calls keep saying they cannot hear you. Before assuming the mic is broken, there are several software and settings causes that are far more likely. This guide covers every fix in order from easiest to most advanced.

Step 1: Check If the Microphone Is Muted

This sounds obvious, but physical mute buttons on headsets and USB microphones are easy to bump accidentally. Check the physical mute button on your headset or microphone first. On Windows, right-click the speaker icon in the taskbar, click "Open Sound settings", scroll to "Input", and make sure the microphone is not muted and the volume is not at zero.

Step 2: Set the Correct Microphone as Default Input

Windows often switches the default microphone when you plug in a new device. If you have multiple audio devices connected — a headset mic, webcam mic, or built-in mic — Windows may be using the wrong one. To fix this:

Step 3: Check App Permissions for the Microphone

Modern operating systems require apps to have explicit permission to use your microphone. If an app like Zoom, Discord, or Chrome cannot access the mic, it is usually a permissions issue.

Step 4: Fix Microphone in Discord

Discord has its own audio settings that override the system defaults. If your mic works in other apps but not Discord:

1. Open Discord → User Settings (gear icon) → Voice & Video
2. Under "Input Device", make sure the correct mic is selected (not "Default")
3. Speak — the Input Sensitivity bar should move
4. If it does not move, scroll down and click "Reset Voice Settings"
5. Also check that you are not server-muted (a red microphone icon in the bottom left)

Step 5: Fix Microphone in Zoom

1. Open Zoom → click your profile picture → Settings
2. Go to Audio tab
3. Under Microphone, select the correct device from the dropdown
4. Click "Test Mic" — speak and check if the input bar moves
5. Make sure "Automatically adjust microphone volume" is checked

Step 6: Update or Reinstall Audio Drivers

On Windows, corrupted audio drivers cause microphone failures that look like hardware problems. Open Device Manager (Windows + X), expand "Sound, video and game controllers" and "Audio inputs and outputs", right-click your microphone device, and select "Update driver". If updating does not help, try "Uninstall device" and then restart Windows — it will reinstall the driver automatically.

Step 7: Test on Another Device

If none of the above fixes work, test your microphone on a different device. Plug your headset into a phone or different computer. If the mic works there, the problem is in your original computer's software or hardware jack. If it does not work on any device, the microphone itself is physically faulty and needs to be replaced.

If you have ever shopped for headphones and seen a number like "32 ohms" or "250 ohms" on the spec sheet, that is the impedance rating. Most people ignore it, but choosing the wrong impedance for your device is one of the most common reasons headphones sound quiet, distorted, or thin even when they cost a lot of money.

What Is Headphone Impedance?

Impedance (measured in ohms, Ω) is the electrical resistance of the headphone drivers. Think of it like a water pipe: low impedance is a wide pipe (lets current flow easily), and high impedance is a narrow pipe (needs more pressure — i.e., more power — to push the same amount of current through). The higher the impedance, the more amplifier power the headphones need to reach a good listening volume.

Low Impedance Headphones (Under 50 Ohms)

High Impedance Headphones (150 Ohms and Above)

Mid Impedance Headphones (50–150 Ohms)

This is a compromise range. Mid-impedance headphones work reasonably well directly from a laptop or phone but benefit noticeably from an amp. The Audio-Technica ATH-M50x (38Ω) and many studio monitors sit here — usable anywhere, but better with an amp.

Sensitivity: The Other Half of the Equation

Impedance alone does not tell the full story. Sensitivity (measured in dB/mW) tells you how loud a headphone gets per milliwatt of power. A 32Ω headphone with 88 dB/mW sensitivity might actually be harder to drive than a 150Ω headphone with 105 dB/mW sensitivity. Always look at both numbers together when deciding whether you need an amp.

Do You Need a Headphone Amplifier?

You likely need an amp if: your headphones are over 100Ω, your headphones sound quiet even at maximum volume on your phone or laptop, or the audio sounds thin and lacks bass. A basic USB DAC/amp like the FiiO E10K or Schiit Magni can make a dramatic difference and costs less than most headphones in this category.

Check Your Headphones Are Working Properly First

Before blaming impedance mismatch, verify that both channels are working correctly and the volume is balanced. Use the free test below.

A Windows update should never break your audio — but it often does. Microsoft updates can overwrite, conflict with, or reset audio drivers, causing everything from complete silence to distorted or mono sound. Here is how to fix it without reinstalling Windows.

Fix 1: Run the Windows Audio Troubleshooter

Windows has a built-in audio troubleshooter that catches many post-update issues automatically. Right-click the speaker icon in the taskbar and click "Troubleshoot sound problems". Follow the prompts. This catches missing default devices and service errors in about 30 seconds.

Fix 2: Check If the Audio Service Is Running

Fix 3: Roll Back the Audio Driver

If a Windows update installed a new audio driver that is incompatible with your hardware, rolling back to the previous version often fixes sound immediately.

Fix 4: Uninstall and Reinstall Audio Drivers

Completely removing and reinstalling the driver gives you a clean slate. In Device Manager, right-click your audio device, select "Uninstall device", check "Delete the driver software for this device", and confirm. Restart your PC — Windows will automatically reinstall a compatible driver. If the reinstalled driver still has issues, visit your PC manufacturer's website or your sound card manufacturer's website to download the latest official driver.

Fix 5: Check That the Correct Output Device Is Selected

Updates sometimes reset the default audio output device to a different option. Click the speaker icon in the taskbar, click the arrow next to the volume slider, and check which device is selected. If it shows HDMI or a display device instead of your speakers or headphones, click the correct device to switch.

Fix 6: Disable Audio Enhancements

Some Windows updates re-enable audio enhancements that conflict with certain hardware. Right-click the speaker icon → Sound settings → More sound settings → select your playback device → Properties → Enhancements tab → check "Disable all enhancements" → Apply. This is a common culprit for no-sound or distorted-sound issues after updates.

Fix 7: Use System Restore

If nothing else works, you can use Windows System Restore to revert your system to a point before the update. Search for "Create a restore point" in Start, click "System Restore", choose a restore point dated before the update, and follow the prompts. This does not delete your personal files but will remove the problematic update and any software changes made after that date.

You do not need to spend money on new speakers or headphones to hear a clear improvement in your audio quality. Most devices leave significant performance on the table through default settings that prioritize compatibility over quality. These fixes work on Windows PC, Mac, iPhone, and Android.

1. Set the Highest Audio Format in Windows

Windows often defaults to a lower quality audio format to ensure compatibility. Setting it to the highest your hardware supports is free and makes music and movies sound noticeably cleaner and more detailed.

2. Disable Audio Enhancements (for Cleaner Sound)

Counterintuitively, Windows audio enhancements often make sound worse — they add artificial processing that muddies the audio signal. Disabling them gives you a purer, more accurate sound. In the same Properties window, go to the Enhancements tab and check "Disable all enhancements".

3. Use Equalizer APO for Free Equalizer Control (Windows)

Equalizer APO is a free, system-wide equalizer for Windows that lets you shape your audio output precisely. Combined with the Peace GUI interface, you get a full parametric equalizer. You can boost upper midrange (2–6kHz) for more clarity in voices, cut excessive bass if your headphones are boomy, and apply preset EQ profiles designed for your specific headphone model from websites like AutoEq.

4. Enable Hi-Res Audio on Android

Many Android phones support Hi-Res Audio output but have it turned off by default, especially over USB. If you use a USB-C to 3.5mm adapter or a USB DAC, check Settings → Sound → Audio quality settings (location varies by manufacturer) and enable Hi-Res Audio if available.

5. Use Lossless Audio Formats

The quality of your audio files matters as much as your equipment and settings. Streaming services like Apple Music and Tidal offer lossless audio (FLAC / ALAC) at no extra cost on existing subscriptions. In Spotify, go to Settings → Audio quality and set streaming quality to "Very High". In Apple Music, enable Lossless Audio and Dolby Atmos in Settings → Music → Audio Quality.

6. Check Stereo Balance for Accurate Imaging

Even a slight imbalance in the stereo field makes music sound off-center and kills the sense of space. Before adjusting equalizer settings, make sure both your left and right channels are perfectly balanced. Use our free test to verify this in 10 seconds.

7. Position Speakers or Headphones Correctly

If you use desktop speakers, placement dramatically affects sound quality. Place them at ear level, angled toward you at roughly 30 degrees (an equilateral triangle with your head at the tip). Keep them away from walls and corners, which create bass buildup. Even moving speakers 6 inches away from a wall can noticeably clean up muddy bass.

8. Clean Your Headphone Drivers and Speaker Grills

Dust and debris on speaker drivers reduces high-frequency clarity. Clean headphone earcups and grills with a soft, dry brush or compressed air. Never use liquids directly on driver surfaces. Even gentle cleaning can restore lost high-end detail that has been muffled by accumulated debris.

You plug your laptop or PC into a TV via HDMI, the picture shows up perfectly, but there is no sound from the TV speakers. This is one of the most commonly searched audio problems — and it has several specific causes that are easy to fix once you know what to look for.

Why HDMI Audio Often Fails

HDMI carries both video and audio through the same cable, but your PC needs to send the audio signal to the HDMI output specifically — it does not happen automatically. Most HDMI audio problems are caused by the PC sending audio to the wrong output device, an incorrect driver, or a cable that does not fully support audio.

Fix 1: Set HDMI as the Default Audio Output

This is the most common cause. Windows does not automatically switch audio output to HDMI when you connect a display. You must manually set it as default.

Fix 2: Enable the HDMI Audio Device (If It Shows Disabled)

Sometimes the HDMI audio output is present but disabled. In Sound settings → More sound settings → right-click anywhere in the Playback tab → select "Show Disabled Devices". If you see an HDMI device grayed out, right-click it and select "Enable".

Fix 3: Update the Display / Graphics Driver

HDMI audio on a PC is handled by the graphics card (GPU) driver, not the regular audio driver. An outdated or corrupted GPU driver frequently causes HDMI audio to stop working. Visit the NVIDIA or AMD website (or Intel for integrated graphics) and download the latest driver for your GPU. After installing, restart your PC and check HDMI audio again.

Fix 4: Check the HDMI Cable

Not all HDMI cables support audio — particularly very cheap or very old cables. HDMI 1.4 and above supports audio, but some budget cables marketed as "HDMI" may only carry video. Try a different HDMI cable, preferably one labeled HDMI 2.0. Also check that the cable is seated firmly in both the TV and PC ports.

Fix 5: Check TV Input Settings

Some TVs have audio settings per HDMI input that must be enabled separately. Go to your TV's audio settings and look for options like "Digital Audio Output", "HDMI ARC", or "PCM" format. Set it to PCM (not Dolby Digital Auto or Bitstream) first, as this is the most universally compatible format.

Fix 6: Fix HDMI Audio on Mac

Fix 7: Fix HDMI Audio on Gaming Consoles

On PlayStation 5: Settings → Sound → HDMI Device Type → make sure it matches your TV type (TV or AV Amplifier). Set Audio Output to HDMI. On Xbox Series X/S: Settings → General → Volume & audio output → HDMI audio → select "Stereo uncompressed" to rule out format issues.
