No Sound on Windows 11? 10 Fixes That Actually Work
⚡ Quick Answer
When Windows 11 has no sound, first run a browser sound test to confirm the problem, then check the output device (click the speaker icon and confirm the right device is selected), unmute and raise the volume mixer, and restart. If that fails, reinstall the audio driver in Device Manager and restart the Windows Audio service. One of these fixes resolves the vast majority of cases.
Before Anything Else: Isolate the Problem
'No sound' has three completely different failure points: the app, Windows, or the hardware. Thirty seconds of testing tells you which one you're fighting, and saves you from reinstalling drivers when the actual problem was a muted browser tab.
Open the browser sound tester and play the test tones. Then try a YouTube video, then a local file. If the browser test plays but one specific app is silent, it's that app's settings or its slider in the volume mixer. If nothing plays anywhere, it's Windows or hardware — work through the fixes below in order.
- Play the browser test tones — Confirms whether Windows can output audio at all.
- Try one other source — A video or local file rules single apps in or out.
- Plug in headphones — Headphones working while speakers stay silent points straight at speaker hardware.
- Branch — One silent app → volume mixer (fix 2). Everything silent → fixes 1, 3–10 in order.

Open Sound Tester →The 10 Fixes, In Order of Likelihood
1. Check the output device
Click the speaker icon in the taskbar, then the arrow next to the volume slider. Windows 11 loves silently switching output to a monitor, TV or Bluetooth device you paired weeks ago. Select your actual speakers or headphones.
2. Check the volume mixer
Right-click the speaker icon → Open volume mixer. Each app has its own slider, and individual apps can be muted while the master volume looks fine. This catches an embarrassing number of 'no sound' cases.
3. Restart the computer
Unglamorous, effective. Audio services and drivers get into states that only a restart clears — especially after Windows updates or sleep/wake cycles.
4. Run the audio troubleshooter
Settings → System → Troubleshoot → Other troubleshooters → Playing Audio. It automatically fixes disabled devices, wrong defaults and stopped services.
5. Reinstall the audio driver
Right-click Start → Device Manager → Sound, video and game controllers → right-click your audio device → Uninstall device (don't tick 'delete driver') → restart. Windows reinstalls it cleanly on boot. If sound broke right after a driver update, choose 'Roll back driver' on the Driver tab instead.
6. Restart the Windows Audio service
Press Win+R, type services.msc, find Windows Audio, right-click → Restart. Also restart Windows Audio Endpoint Builder. If either was stopped, you've found your culprit — set both to Automatic startup.
7. Disable audio enhancements
Settings → System → Sound → select your device → Properties → turn off Audio enhancements. Enhancement software conflicts cause silence, crackling and distortion on some hardware.
8. Turn off exclusive mode
In the same device properties, under Advanced: untick "Allow applications to take exclusive control of this device." Some apps (often audio production software) grab the device exclusively and mute everything else — and don't always give it back.
9. Check spatial sound settings
Settings → System → Sound → device Properties → Spatial sound: set to Off. Misconfigured spatial audio occasionally kills output entirely on certain devices, particularly after headphone-to-speaker switches.
10. Check for Windows updates — or uninstall the latest one
Both directions matter: a pending update may contain the audio fix, while a just-installed update may have caused the problem (Settings → Windows Update → Update history → Uninstall updates).
👤 Real-Life Scenario
Grace, a teacher in Sheffield, lost all sound the night before online parents' evenings. The browser sound test confirmed total silence; the output device menu revealed why — Windows had switched output to "LG TV" (the living-room telly she'd screen-cast to at the weekend, now off). One click back to Speakers and everything worked. Total fix time: 40 seconds.
The HDMI/Monitor Gotcha Everyone Hits Eventually
Plug a laptop into a monitor or TV over HDMI or USB-C and Windows routes audio to that screen — because HDMI carries sound. If the monitor has no speakers (many don't), the result is perfect silence with no error message anywhere.
The fix is fix #1 above: manually select your laptop speakers or headphones as output. If you dock and undock daily, expect to do this occasionally — Windows' memory of per-device defaults is imperfect, especially across docking stations.
Still Silent? Deciding If It's Hardware
| Test | Result | Conclusion |
|---|---|---|
| Plug in headphones | Headphones work, speakers don't | Speaker hardware or connection fault |
| Plug in headphones | Both silent | Software/driver — keep working the list |
| Boot into BIOS/UEFI or safe mode | No audio anywhere ever | Likely hardware failure |
| Try a USB audio device | USB audio works | Onboard audio chip fault; USB adapter is a cheap workaround |
Genuinely dead onboard audio is rare and, on laptops, usually not economical to board-repair — but a USB audio adapter costs very little and restores sound through any USB port.
