How to Fix No Audio or Sound in Windows 11

The Problem

Volume is up, the mixer shows activity, but the speakers or headphones stay silent—often after a Windows update or a driver change. On Windows 11 this is usually the wrong output device, a stopped audio service, or a driver that needs reinstalling, not dead hardware.

Quick Checks First

  1. Mute. Check the keyboard mute key, the headset's inline control, and the volume icon in the tray.
  2. Physical connection. Powered speakers plugged in and switched on; the cable in the green jack, not the pink or blue one.
  3. Bluetooth. Headphones paired, connected, and charged—see Bluetooth not working.
  4. Try another app. If one app is silent and everything else works, jump to Step 3.

Step 1: Pick the Right Output Device

Windows is frequently sending audio somewhere real but silent—an HDMI monitor with no speakers is the classic case.

  1. Click the volume icon in the system tray.
  2. Click the > arrow next to the volume slider.
  3. Choose your actual speakers or headphones from the list.
  4. For more control: Settings → System → Sound → Output, select the device, and set Volume on that device.

If your device is not listed at all, go to Step 4.

Step 2: Restart the Audio Services

The audio service can stop silently, and everything then looks normal while producing nothing.

  1. Press Win + R, type services.msc, press Enter.
  2. Find Windows Audio → right-click → Restart (or Start if it is stopped).
  3. Do the same for Windows Audio Endpoint Builder.
  4. Double-click each and confirm Startup type is Automatic.
  5. Also restart Remote Procedure Call (RPC) dependencies only if the audio services refuse to start—they depend on it.

If the services will not stay running, see fix audio services not responding.

Step 3: Check the Volume Mixer

An individual app can be muted while the system is fine.

  1. Right-click the volume icon → Open Volume mixer.
  2. Check the slider and mute state for each running app.
  3. In the same panel, confirm each app is pointed at the correct output device—Windows 11 allows per-app output routing, and an app stuck on a disconnected device produces silence in that app only.

Step 4: Reinstall the Audio Driver

  1. Right-click Start → Device Manager.
  2. Expand Sound, video and game controllers.
  3. Right-click your audio device (Realtek Audio, Intel SST, NVIDIA High Definition Audio) → Uninstall device. Do not tick "remove driver software" on the first attempt.
  4. Restart. Windows reinstalls its generic driver automatically, which is often enough to restore sound.
  5. If sound returns but quality or features are missing, install the OEM audio package from your laptop or motherboard maker's support page.

Missing device entirely? View → Show hidden devices, and look under Other devices for an unknown device with a yellow triangle.

Step 5: Disable Audio Enhancements

Vendor effects processing is a common cause of complete silence after an update.

  1. Press Win + R, type mmsys.cpl, press Enter.
  2. Playback tab → double-click your device → Enhancements tab (if present) → tick Disable all enhancements.
  3. On the Advanced tab, change the Default Format to 16 bit, 48000 Hz (DVD Quality) and untick Allow applications to take exclusive control.
  4. Click Apply and test.

The exclusive-control setting matters: an app that grabbed the device and crashed can leave it locked, silencing everything else until you restart the service.

Step 6: Run the Troubleshooter

Settings → System → Troubleshoot → Other troubleshooters → Audio → Run. It restarts the endpoint builder and resets device defaults, which resolves a fair share of cases without further work.

Step 7: Roll Back a Recent Update

If sound stopped the day an update installed:

  • Roll back the audio driver: Device Manager → device → Properties → Driver → Roll Back Driver.
  • Or remove the Windows update: fix Windows 11 after a bad update.

Step 8: Repair System Files

DISM /Online /Cleanup-Image /RestoreHealth

What Not to Do

  • Don't install a "sound driver" from a search result. Audio drivers come from your PC maker or Windows Update; downloadable driver packs are a known malware channel.
  • Don't set the default format to 24-bit 192 kHz hoping for better sound. It is a common cause of crackling and dropouts on integrated audio—see fix crackling or popping sound.

Still Silent?

Plug in a cheap USB headset or USB DAC. If that produces sound, the motherboard's analogue output or the front-panel header is at fault—a hardware issue with an easy workaround. If even a USB device is silent, the problem is Windows-side and worth a fresh user profile test before anything more drastic.

Microphone works but no output, or the reverse? Input problems are separate: fix a microphone not working. Sound comes out of the wrong device? See headphones not detected or wrong audio output.
