[Mozilla Enterprise] No sound on websites with 78esr

[Timo Pietilä]

I had that same problem and to me sandbox.content to 5 fixed the 
problem. Required FF restart after changing that setting before it 
worked, but now I'm getting sounds from videos.

Same problems: connection to remote machine with RDP -> no sound from FF 
videos played at remote end.
