Firefox no sound after upgrade to Windows 8.1

more options

Recently I updated from Windows 8 to 8.1 After doing so Firefox will not play any form of sound at all. Or I have to turn my PC volume to 100% plus the video volume max and I can hear the video or sound very faintly.

I've done a reset, reinstall, went to troubleshooting for the sound section and nothing is fixing the problem? I have no idea what to try next or why it's not laying sound at all. It's really starting to bug me.

Chosen solution

Is it just Flash content that you are experiencing issues with or all sound content?
Can you hear this music file?

Please try disabling both the Flash and Firefox hardware acceleration.
