When sound suddenly stops working in Windows 10, crackles, or plays from the wrong device, restarting the audio driver or the Windows Audio service often fixes it without rebooting the whole PC. This guide covers the quickest ways to restart audio: restarting the audio services, disabling and re-enabling the audio device, reinstalling the driver, and running the audio troubleshooter.
Quick Answer
Press Windows key + R, type services.msc, and press Enter. Right-click Windows Audio and choose Restart. If that does not help, open Device Manager, expand Sound, video and game controllers, right-click your audio device, choose Disable device, then right-click again and choose Enable device.
Method 1: Restart the Windows Audio Service
- Press Windows key + R, type services.msc, and press Enter.
- Find Windows Audio.
- Right-click it and choose Restart (or click Restart the service on the left).
- If sound is still missing, also restart Windows Audio Endpoint Builder.
Make sure both services have Startup Type set to Automatic.
Method 2: Disable and Re-enable the Audio Device
- Right-click Start and choose Device Manager.
- Expand Sound, video and game controllers.
- Right-click your audio device (for example, High Definition Audio Device or your PC maker's audio device) and choose Disable device. Confirm.
- Right-click it again and choose Enable device.
Method 3: Command Line (Quick Restart)
Open Command Prompt as administrator and run:
net stop audiosrvnet start audiosrv
This restarts the Windows Audio service. You can save these lines in a .bat file to run whenever audio stops.
Method 4: Reinstall the Audio Driver
- In Device Manager, right-click the audio device and choose Uninstall device.
- Restart the PC. Windows reinstalls the driver automatically.
- If needed, download the latest audio driver from your PC or motherboard maker's website.
Method 5: Run the Audio Troubleshooter
Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters > Playing Audio and click Run the troubleshooter. It can restart services and fix common settings.
Check These Settings Too
- Output device: click the speaker icon in the taskbar and choose the right playback device.
- Volume mixer: right-click the speaker icon, choose Open Volume mixer, and check that apps are not muted.
- Enhancements: in Sound Control Panel > Playback > Properties, turn off audio enhancements if audio crackles.
- Cables and Bluetooth: reconnect headphones or speakers.

Driver glitches, updates, sleep and wake cycles, or Bluetooth issues are common causes. Updating the audio driver often helps.

Yes. The same Services and Device Manager steps apply.
