SEO focus: If you are looking for windows 11 sound not working after update, this guide starts with the fastest diagnosis, then moves to the exact fix that matches the symptom.
Short answer: Windows Updates can replace audio drivers or switch the default playback device. If the audio device vanished, roll back or reinstall the driver. If the device is still listed but silent, select the correct output device first.
Windows 11 Sound Not Working after Update: Quick Diagnosis
Open Settings > System > Sound and check the Output dropdown. If your speakers or headphones appear, Windows still sees the hardware and the problem is usually output selection or driver behavior. If it says No output devices found, the audio driver was removed or corrupted by the update.
Open Device Manager > Sound, video and game controllers. A yellow warning icon points to a driver failure. If the category is missing or the device is gone, reinstall the manufacturer audio driver.
Open the volume mixer. If audio bars move but you hear nothing, Windows is sending sound to the wrong device, often HDMI audio from a monitor or TV.
What to do first
- Go to Settings > System > Sound. Under Output, select the correct speakers or headphones instead of HDMI, NVIDIA High Definition Audio, Intel Display Audio, or another display audio option.
- Open Device Manager > Sound, video and game controllers > right-click the audio device > Properties > Driver. If the Driver Date matches the Windows Update date, click Roll Back Driver, restart, and test.
- If Roll Back is unavailable, download the audio driver from your laptop or motherboard manufacturer. Use Dell, HP, Lenovo, ASUS, MSI, Gigabyte, ASRock, or the correct support page for your exact model.
- Restart audio services: press Win + R, type
services.msc, restart Windows Audio and Windows Audio Endpoint Builder. - Run Settings > System > Troubleshoot > Other troubleshooters > Playing Audio > Run.
- If the audio device is missing, uninstall the broken device from Device Manager, restart, let Windows reinstall a basic driver, then install the proper manufacturer driver.
Common mistake
Checking only the volume slider and mute button wastes time. After updates, the real cause is usually a replaced driver or a switched output device, not the volume level.
Best next step
If the output device is correct and the driver looks healthy but audio still fails, repair Windows audio components with sfc /scannow, then DISM /Online /Cleanup-Image /RestoreHealth, restart, and test again.

Quick Q&A
Sound works through HDMI but not speakers. Why?
Windows selected HDMI audio as the default output. Switch the Output device back to Realtek, speakers, or headphones in Settings > System > Sound.
Device Manager shows a yellow icon. What does that mean?
The driver loaded but failed to initialize. Roll it back if possible, or install the correct manufacturer driver manually.
Audio worked after the update then stopped later. Why?
The Windows Audio service may have crashed. Restart Windows Audio and Windows Audio Endpoint Builder from services.msc, then run SFC if they keep stopping.
