That symptom usually points to an audio driver, audio format, or audio enhancement issue rather than the video itself.
Try this in order:
- Turn off audio enhancements
- Go to Start > Settings > System > Sound.
- Under Output, select the device being used.
- Scroll to Advanced settings and set Audio enhancements to Off.
- Test the same video again.
- Run the audio troubleshooter
- Go to Start > Settings > System > Troubleshoot > Other troubleshooters.
- In Audio, select Run.
- Check that the correct output device is selected
- Go to Start > Settings > System > Sound.
- Under Output, confirm the intended speakers are selected.
- If needed, open More sound settings > Playback, right-click the correct device, and select Set as default.
- Try a different audio format
- Search for Control Panel and open it.
- Select Hardware and Sound > Sound.
- On the Playback tab, right-click the default device and select Properties.
- Open the Advanced tab.
- Change Default Format, select OK, and test playback. If needed, try another format.
- Restart Windows Audio services
- Search for Services and open it.
- Restart these services:
- Windows Audio
- Windows Audio Endpoint Builder
- Remote Procedure Call (RPC)
- Update the audio driver
- First use Start > Settings > Windows Update > Check for updates.
- If no newer driver is installed, open Device Manager.
- Expand Sound, video and game controllers.
- Right-click the audio device and select Update driver > Search automatically for drivers.
- Reinstall the audio driver
- In Device Manager, right-click the audio device under Sound, video and game controllers.
- Select Uninstall device.
- Restart the PC so Windows reinstalls the driver.
- This can temporarily remove sound until restart completes.
- If the device shows IDT High Definition Audio CODEC
- In Device Manager, expand Sound, video and game controllers.
- If IDT High Definition Audio CODEC appears, select Update driver > Browse my computer for drivers > Let me pick from a list of available drivers on my computer.
- Select High Definition Audio Device and continue.
For a Dell system, if the issue started after a Windows 11 update, Windows may have replaced the Dell audio driver with a generic one. In that case, reinstalling the latest Dell audio driver package is often the next step after the Windows troubleshooting above.
