sound just disappears randomly when watching flash video in firefox

[Alexander Langanke]

Binary package hint: pulseaudio

When watching a Flash Video (for example on YouTube) in Firefox, sound just disappears systemwide.

Restarting Firefox does not fix the problem. I have to log out and back in to my desktop session or restart my PC to get sound back.

I cannot reproduce the bug at will. It just randomly appears.
