No Sound Troubleshooting Guide: Fix Audio on Your Computer
Overview
No Sound Troubleshooting Guide. The No Sound Troubleshooting Guide walks you through complete silence one step at a time: click Play Test Tone to check your browser, List My Audio Outputs to confirm the right device is active, then pick your Windows, macOS, or Mobile tab for the exact restart steps before you play the tone again to confirm the fix worked. Each step has a live test built in, so you know whether that step solved it before you move on to the next one. The binaural beats generator online gives you full control over frequency and volume before you start.
This no sound troubleshooting guide takes you from the quickest checks to deeper repairs when your computer goes silent, whether it is the built-in audio, your headphones or a monitor that stays quiet. Work through the steps in order, because most audio problems turn out to be a muted volume, the wrong playback device or an outdated driver. If you search for no sound on computer fixes and find ten different answers, this order tells you which one to try first.
Why Your Computer Has No Sound
Silence almost always comes down to one of a handful of causes. Knowing which one applies saves you from changing settings that were never broken. Software issues are far more common than physical faults, so start there before you blame the equipment. The free audio frequency range reference is written to be skimmed — find your answer in seconds.
Wrong playback device or muted volume
Audio problems usually show up in one of three ways: nothing plays, audio plays from the wrong device, or the audio is distorted. Sorting your symptom into one of these groups tells you whether to look at settings, drivers or the equipment. Audio issues that appear right after an update point to the driver, while audio problems that began after you connected a new headset point to the active output.
Windows can send sound to the built-in speakers, headphones, a monitor, a Bluetooth speaker or a USB headset. If the wrong one is the default, you hear nothing from the device in front of you. A mute in the volume mixer, or a keyboard key that was pressed by accident, has the same effect on every audio output.
Outdated driver or a stopped Windows service
A Windows update can swap a working driver for a generic driver that does not fully support your hardware. In Device Manager you may then see a yellow triangle next to the sound device, or the device may vanish. Separately, the Windows Audio Endpoint Builder and its companion service must be running, or every app falls silent at once.
Hardware failure in speakers, jacks or the sound card
Laptop speakers can burn out at high volume, a loose audio jack stops passing a signal, and on older desktops the sound card itself may fail. When every software fix has failed, a hardware failure is the likely culprit, and testing with a second device confirms it.
How to Fix No Sound on Your Computer in Windows
These steps apply to Windows 11 and Windows 10, and the menus differ only slightly. Begin with the first step, test your audio after each one, and stop as soon as you hear audio. Playing a short clip in your browser after every change is the quickest way to troubleshoot without guessing. Check the headphone impedance guide online before you assume the worst about what you're seeing.
Check cables, plugs and power
Look at the simple things first. Confirm that the cables run from your computer to the speakers or headphones and sit fully in the right jack, because a surround system may have several. A green jack usually carries output and a pink one carries the microphone.
- Make sure external speakers are switched on and plugged into power.
- Try another USB port or a different audio jack to rule out a damaged connection.
- Plug the same speakers or headphones into a phone or laptop to see whether they work elsewhere.
- Unplug headphones, since some laptop speakers stay silent while a plug is inserted.
Check volume, mute and sound settings
If you cannot check for no sound because the speaker icon is missing from the taskbar, right-click the taskbar, choose Taskbar settings and turn on the volume icon. The speaker icon may also hide in the overflow area, so click the arrow on the taskbar to show hidden icons and look again.
Click the speaker icon in the taskbar and drag the volume slider well above zero. Next, right-click the same icon, open the volume mixer and make sure no app shows an x beside its slider. Some speakers and programs carry their own volume controls, so check those as well.
- Select Start > Settings > System > Sound.
- Under Advanced, choose More sound settings to open the Sound Control Panel.
- On the Playback tab, right-click your device, choose Properties and confirm that Use this device (enable) is selected.
- Switch to the Levels tab and make sure the speaker is not muted.
Select the correct output device
In the same sound settings page, open the Output list and pick the speakers or headphones you actually want to hear. Choosing an output device there also makes it the default device for most apps. If you are unsure which entry is yours, click each in turn and use the Test button.
If several entries share a similar name, unplug all but one, confirm that this output device carries audio, then reconnect the rest, and keep that output device as the default audio choice. The output device that disappears when you unplug its cable is the one you were trying to hear.
Older apps sometimes ignore that choice. In the Playback tab, right-click the right entry, select Set as Default Device and click Apply. If you recently attached a gaming headset, it may have taken over as the default audio device without telling you, so restart the app after switching.
Run the audio troubleshooter
The built-in audio troubleshooter checks disabled devices, wrong defaults and some driver faults automatically. On Windows 11 open Start > Settings > System > Troubleshoot > Other troubleshooters, find Playing Audio and click Run. It will not fix everything, but it takes under a minute, and its result tells you whether the fault is a setting or a deeper problem.
Turn off audio enhancements
Sound effects add processing that can clash with a driver. Open Settings > System > Sound, choose your device under Output, scroll to Advanced settings and switch audio enhancements to Off. On older Windows 10 builds, open the Enhancements tab in Properties and tick Disable all sound effects.
Restart the Windows audio service
Press Win + R, type services.msc and press Enter. Find Windows Audio, and if the Status column does not say Running, right-click it and choose Start; if it is running, choose Restart. Repeat for Windows Audio Endpoint Builder. From an administrator Command Prompt you can also run net stop audiosrv && net start audiosrv and then restart the computer and test your audio again, since the audio stack reloads on boot.
Fix Audio Problems with Audio Driver Updates
If the settings look right, the driver is next in line. A driver is the software that lets Windows talk to your audio hardware, and a corrupted or mismatched one stops playback entirely. Updating, reinstalling or rolling back usually restores your audio.
Update or reinstall audio drivers
Type Device Manager into the taskbar search and open it. Expand Sound, video and game controllers, right-click your audio device and choose Update driver, then Search automatically. If that changes nothing, choose Uninstall device, tick Delete the driver software for this device, confirm, and restart the computer so Windows installs a fresh copy. On a Dell, SupportAssist can scan for the correct audio drivers and install them for you.
Roll back a driver after a Windows update
Manufacturers publish audio drivers on their support pages, and downloading audio drivers from the maker of your computer is safer than using a driver pack from an unknown site. Open Device Manager again afterwards to confirm the yellow triangle is gone and the audio device reports that it is working properly.
When the silence began right after an update, go back one version. In Device Manager, right-click the audio device, open Properties, select the Driver tab and press Roll Back Driver if the button is available. If rolling back is greyed out, a System Restore point from before the update can undo the change without touching your files.
Check Realtek, Intel and NVIDIA hardware drivers
Most desktops and laptops use Realtek audio, while Intel Smart Sound and NVIDIA or AMD High Definition Audio handle sound sent over HDMI. Your computer may list several of these, and each one needs a working driver. On some Dell and Lenovo models the entry reads IDT High Definition Audio CODEC; right-click it, choose Update driver, browse manually, and pick High Definition Audio Device from the list.
Install pending updates and restart
A missing audio driver update can leave you with no sound, so open Settings > Windows Update and select Check for updates. Install everything offered, including optional driver updates, then restart so the changes take effect. A restart alone clears many temporary glitches, so do not skip it even when the installer does not insist.
Try a different audio format
If you still have no sound after updating drivers, a format your hardware cannot handle produces silence or popping. In the Playback tab, double-click your device, open the Advanced tab and pick another sample rate and bit depth from the drop-down. Press Test after each change, and repeat with other combinations until you hear a tone.
No Sound on Windows When You Use HDMI, a Monitor or a TV
Connecting a second screen changes where Windows sends sound. If the display has no speakers, or you left its volume at zero, the room stays quiet even though everything else is fine.
Sound goes to the TV instead of your speakers
When you plug in an HDMI or DisplayPort cable, Windows often makes the screen the default output. Open Settings > System > Sound and switch the output back to your speakers or headphones. If you want the TV to play the audio, select the HDMI entry and raise the volume on the TV as well. Many TVs also have their own audio settings menu, and its audio output may be set to an external receiver.
No HDMI option in the output list
If you get no HDMI sound because the display never appears under Output, reseat the cable at both ends and try another port. Then open Device Manager and confirm that the NVIDIA, AMD or Intel graphics driver is installed, since HDMI audio travels through it. DisplayPort behaves the same way, and a cheap adapter that carries only video is a frequent cause.
Monitors with built-in speakers
Some monitors have speakers but need an audio source selected in their own on-screen menu. Use the monitor's buttons to enable the speakers, then pick the monitor in your Windows sound settings. A monitor connected through a video-only cable cannot play sound at all.
Headphones, Bluetooth and USB: Sound Not Working
External devices add more places for the signal to fail. The fastest approach is to isolate which side of the connection is faulty.
Headphones work but speakers do not
Plug in wired headphones or pair Bluetooth ones. If you hear sound through the headphones but not through the speakers, the speakers, their cable or the jack are the problem. If both stay silent, the cause lies in the audio driver, the service or the onboard chip instead. Check the headphone jack for lint or a bent contact, and try a different cable.
- Test the speakers on another device to confirm they still work.
- Look for a physical volume knob or switch on external speakers.
- Press the speakers lightly while playing sound; a rattle points to a damaged connector.
- Laptop speakers that stay silent at every volume may be blown speakers, which need a repair.
Bluetooth audio keeps failing
If your Bluetooth headset gives no sound, switch Bluetooth off and on, remove the device and pair it again. Make sure the headset is charged and set as the default device. A headset can connect for calls yet stay silent for music, so check which profile Windows selected in the Sound settings page.
Audio Troubleshooting on Ubuntu
If your Ubuntu computer has no sound, note that it uses ALSA and PulseAudio instead of the Windows stack. Check that cables are connected, open Settings > Sound, and confirm the correct output is chosen and not muted. If that fails, reinstall the sound packages with sudo apt install --reinstall alsa-base pulseaudio, then restart the sound server or reboot. Run sudo apt update && sudo apt upgrade so the kernel and drivers match, and play a sound test from the settings panel to confirm the repair.
More Audio Issues: Microphone, BIOS and Hardware
Some less common causes of no sound sit outside the usual settings. They are less common, but they explain stubborn cases where nothing else helps.
Update the BIOS or UEFI
If every other fix leaves your computer with no sound, restart it and open the BIOS or UEFI setup, usually with F2, F10 or Delete. Under the Advanced menu, make sure the onboard sound card is enabled. If it is on and you still hear nothing, check the manufacturer's page for a newer firmware and follow its instructions, since a failed update can leave the machine unusable.
Fix microphone privacy settings
Open Settings > Privacy & security > Microphone and allow apps to use it, then choose the right input device in the sound settings. This fixes a silent microphone, not playback, but it belongs beside the no-sound fixes because a headset needs both.
Audio Troubleshooter and Manufacturer Tools for Audio Issues
When you still have no sound, computer makers ship their own diagnostics, and Dell's SupportAssist also scans for missing audio updates. Dell offers a built-in sound test that plays an audio tone through each speaker and reports whether the hardware responds. HP and Lenovo publish support pages with driver downloads matched to your exact model. If the Windows audio troubleshooter cannot fix the fault, these tools tell you whether the hardware is healthy, which narrows the search and separates sound problems from repair jobs quickly.
Use them when you want to troubleshoot audio issues without guessing: a passing hardware test means the cause is almost certainly software, while a failing test points toward repair.
Fix Sound That Crackles, Distorts or Lags
Not every fault is total silence, and sometimes the fixes above bring sound back but leave it faulty. Other common audio symptoms include distorted sound, crackling or popping, audio lag where voices trail the picture, one-sided sound from a single speaker, and low volume even at maximum. The same fixes apply, with a few twists for each symptom.
- Crackling and distortion: lower the volume, turn off audio enhancements and try another audio format.
- Audio lag: restart a Bluetooth connection, update the headset firmware or switch to a wired headset.
- One-sided sound: check the plug is fully seated and the balance setting is centred.
- Low volume: raise the level in the app, the volume mixer and on the speakers themselves.
Prevent Future Sound Problems
A little maintenance keeps the fault from returning. Install Windows updates on your computer promptly, but create a System Restore point first. Keep the audio software and drivers on your computer current through the manufacturer's tool, avoid yanking cables out while audio plays, and keep speakers away from heat and dust. Review your settings so audio issues do not return after you connect a new headset or monitor, because that is when the default changes.

When to Get Professional Help for No Sound from Your Computer
If you have tried every step and still hear nothing, a technician can test the sound card, the jack and the motherboard. Hardware repairs such as replacing damaged speakers are cheap on a desktop and costlier on a laptop. Before you hand the machine over, note which audio tests passed and which audio device Windows lists, so the repair shop does not repeat them. Mention whether the fault affects music or a video call, since that helps a technician narrow it down.
