No sound in Firefox only.

No sound in firefox only. Videos play fine, just no sound. I've tried everything I've found on here.

I tried refreshing. I tried deleting the C:\Users\UserName\AppData\Roaming\Mozilla\firefox folder and reinstalling. I usually keep flash disabled, I even tried enabling it.

Sound works fine in everything else, opera, internet explorer, it's only this one browser. It used to work fine. I rarely watch videos with firefox so I'm not sure how long it's broken.

This turned out to be a minor symptom of a larger problem.

Due to installing windows 10 under a win7/win10 dual boot setup, and using the same user folder for both OS's, the security settings for said user folder got messed up and caused a recursive error that created endless "application data" folders, each inside the last.

So I wiped the C: drive and reinstalled the OS. I would've gone much faster if MS wasn't sabotaging windows update for win7 but I found the right ones to manually install and all is good now.
