No Sound on Windows 11? Here's Every Real Fix

Wrong output device selected

This is the most common cause by far, and the easiest to fix. Windows remembers the last audio output you used, and it switches automatically whenever a new one becomes available, plugging in headphones, connecting to a monitor over HDMI, or pairing a Bluetooth speaker. If that device then disconnects, or if you switch rooms or displays, Windows can be left pointed at an output that's no longer there, or one you're not near.

1. Click the speaker icon in the bottom-right corner of the taskbar.
2. Click the small arrow next to the volume slider, or open Settings → System → Sound.
3. Under "Output," confirm the device listed is the one you actually want, your laptop speakers, a specific pair of headphones, or a specific monitor.
4. If the right device isn't listed at all, it may be disabled. In Sound settings, click "All sound devices" and check for it there, then enable it if it shows as disabled.

Outdated or corrupted audio drivers

The audio driver is the software layer between Windows and your sound hardware. If it's outdated, corrupted, or mismatched with your hardware, sound can stop working entirely, play with heavy distortion, or work in some apps but not others.

1. Right-click the Start button and choose Device Manager.
2. Expand "Sound, video and game controllers."
3. Look for a yellow warning triangle on your audio device, that's a clear sign the driver has a problem.
4. Right-click the device and choose "Update driver," then "Search automatically for drivers."
5. If Windows finds nothing better, visit your laptop manufacturer's support site (or your sound card manufacturer's, on a desktop) and download the current driver directly, rather than relying only on Windows Update.

Run the built-in audio troubleshooter

Before manually digging through settings, Windows 11 has a built-in diagnostic that catches a surprising number of common issues automatically.

1. Go to Settings → System → Sound.
2. Scroll down to "Troubleshoot common sound problems" and click it.
3. Follow the prompts. It checks for muted or disabled devices, a stopped audio service, and basic driver issues, and offers to fix anything it finds.

It won't fix a genuinely corrupted driver install or failing hardware, but it's worth the two minutes it takes before moving to more manual steps.

Windows Audio service not running

Sound in Windows depends on a background service called "Windows Audio." If it's stopped, disabled, or crashed, you get complete silence with no other symptoms, everything else in Windows looks normal.

1. Press Windows key + R, type services.msc, and press Enter.
2. Scroll down and find "Windows Audio."
3. Check the Status column. It should say "Running." If it doesn't, right-click it and choose "Start."
4. Right-click it again, choose Properties, and make sure "Startup type" is set to "Automatic," not "Disabled" or "Manual," so it starts on its own after every restart.
5. Also check "Windows Audio Endpoint Builder" directly above it in the list, and do the same for it, both services need to be running.

HDMI and Bluetooth device conflicts

Connecting to an external display over HDMI often brings audio along with video, and Windows will sometimes default to that display's speakers (or lack of any) instead of your laptop's built-in speakers. Bluetooth headphones or speakers cause a similar issue: if one is paired but not actually connected, or if two Bluetooth audio devices are paired at once, Windows can get confused about where sound should go.

Symptom	Likely cause	Fix
Sound worked before connecting a monitor, now silent	Output switched to the HDMI display	Reselect your speakers/headphones in Sound settings
Bluetooth headphones show "connected" but no audio	Paired for calls only (HFP profile), not media (A2DP)	Unpair and re-pair, then select the "stereo" or "media" audio device, not the "hands-free" one
Two Bluetooth devices paired, audio goes to the wrong one	Windows picked a different default than expected	Disconnect the one you're not using, or manually select the output device

A Windows update broke your audio drivers

If your sound worked fine and then stopped right after a Windows update, this is the most likely explanation. Updates occasionally overwrite a manufacturer-specific audio driver with a generic Microsoft one, which can be less capable or simply incompatible with your specific hardware.

1. Open Device Manager, expand "Sound, video and game controllers," right-click your audio device, and choose Properties.
2. Go to the "Driver" tab and click "Roll Back Driver," if that option is available (it's greyed out if there's no previous driver to roll back to).
3. If rollback isn't available, download the correct driver directly from your manufacturer's website and install it manually, this typically resolves the issue even when Windows Update caused it.
4. Restart your computer after any driver change, audio drivers in particular often don't take effect until a full restart.

App-specific volume muted in the mixer

Windows lets you control the volume of individual apps separately from the system volume, and it's easy to accidentally mute one app while everything else still works fine. If sound plays in some apps but not others, this is almost always the cause.

1. Right-click the speaker icon in the taskbar and choose "Open Volume mixer."
2. You'll see a slider for each open app that's currently using audio.
3. Check that the app you're expecting sound from isn't slid all the way down or shown with a muted speaker icon.

If you're troubleshooting a laptop that's also showing other odd behavior after the same update, our guide on a black screen after startup covers a similar update-related pattern with display drivers, worth a look if more than just audio changed.
