For intermittent sound cutouts while watching a movie on Windows 11, use this order:
- Check the selected output device.
- Select the Speakers icon on the taskbar.
- Select the arrow next to the volume slider.
- Confirm the movie audio is going to the correct device, such as the intended speakers or headphones.
- Check hardware and volume controls.
- Make sure speaker or headphone cables are fully connected.
- If using USB audio, try a different USB port.
- Make sure the device is powered on and not muted.
- If headphones are plugged in, unplug them and test again.
- Turn off audio enhancements.
- Go to Start > Settings > Sound.
- Under Output, select the audio device in use.
- In Advanced settings, set Audio enhancements to Off.
- Test the movie again.
- Run the audio troubleshooter.
- Go to Start > Settings > System > Troubleshoot > Other troubleshooters.
- In Audio, select Run.
- Try a different audio format.
- Open Control Panel > Hardware and Sound > Sound.
- On the Playback tab, right-click the default device and select Properties.
- On the Advanced tab, change Default Format, select OK, and test audio.
- Restart Windows audio services.
- Search for services and open it.
- Restart these services:
- Windows Audio
- Windows Audio Endpoint Builder
- Remote Procedure Call (RPC)
- Update or reinstall the audio driver.
- Open Device Manager.
- Expand Sound, video and game controllers.
- Right-click the audio device and select Update driver.
- Restart the PC.
- If the issue continues, uninstall the driver and reinstall it from the device manufacturer’s website.
- If the device shows IDT High Definition Audio CODEC, try the manual driver switch.
- In Device Manager, expand Sound, video and game controllers.
- Right-click IDT High Definition Audio CODEC > Update driver.
- Select Browse my computer for drivers > Let me pick from a list of available drivers on my computer.
- Select High Definition Audio Device and continue.
If the cutout happens only in one movie app while other system sounds work normally, that points to an app-specific audio issue rather than the whole Windows audio system.
