"Audio renderer error. Please restart your computer." — fix without restarting
Windows-specific YouTube error where the audio output device disconnects or changes mid-playback. The system message says to restart, but most cases are fixable in 30 seconds without rebooting.
Why this happens
- Audio output device changed (headphones unplugged, Bluetooth disconnected, monitor with built-in speakers went to sleep).
- Windows audio service crashed or stalled.
- Audio driver conflict — usually after a Windows Update.
- Sample rate mismatch between the audio source and the output device.
How to fix it
- 1
Pause the video, switch audio device once, switch back
Right-click the volume icon → Sound settings → switch the output device to anything else, then switch back. This forces the audio renderer to re-bind and clears the error 90% of the time. Faster than a restart.

Restart Windows Audio service
Win+R → services.msc → find Windows Audio → right-click → Restart. No reboot needed.
- 3
Set sample rate to 16-bit, 48000 Hz
Right-click volume → Sound → Properties of your output device → Advanced. Set Default Format to "16 bit, 48000 Hz (DVD Quality)". Sample-rate mismatch with USB audio devices is a common silent cause.

Roll back recent audio driver
Device Manager → Sound, video and game controllers → right-click your audio device → Properties → Driver → Roll Back Driver. Do this if the error started after a Windows Update.
