Random firefox sound,what to do?
Well,when I go to the volume mixer the sound icon for firefox keeps flashing so as a result some youtube videos have sound,others not and some have distorted sound.

Right click the volume icon, choose Open Volume Mixer from
the pop-up menu. You will see the audio device and various apps in the Volume Mixer. Make sure the slider
for Mozilla Firefox is not muted or at the bottom. Restart the Firefox browser and try to play any embedded videos online again.
