Can't play audio in Facebook with Firefox Windows 11

Using Firefox, after updating to Windows 11, when I am in Facebook, I cannot unmute any video sound. I can play sound in other apps on the same computer.

Answer 1

If you are unable to play audio on Facebook using Firefox after updating to Windows 11, there are a few troubleshooting steps you can try:

1. Check Volume Settings: Ensure that the volume for the Firefox browser is not muted. You can check this by right-clicking the speaker icon in the system tray and selecting "Open Volume Mixer" to see if Firefox is muted.
2. Update Audio Drivers: Make sure your audio drivers are up to date. You can do this by going to Device Manager, locating your audio device, and checking for driver updates.
3. Check Firefox Settings: Sometimes, specific settings in Firefox can affect audio playback. Ensure that audio is enabled in Firefox settings and that there are no extensions interfering with audio playback.
4. Try Other Browsers: If the issue persists, try accessing Facebook using a different browser (like Edge or Chrome) to see if the problem is specific to Firefox.
5. Reset Firefox: If none of the above steps work, consider resetting Firefox to its default settings. This can resolve issues caused by corrupted settings or extensions.

If the problem continues after trying these steps, it may be worth checking for any known issues with Windows 11 and Firefox audio playback, as updates can sometimes introduce new bugs.
