Running
pulseaudio -k
thenpulseaudio -d
should restart pulseaudio and temporarily fix your issue. For a more complete fix that doesn't stop working, I had to download the latest flash and install manually. This should work for you on firefox - other browsers may need the libflashplayer.so placed elsewhere. Google should help if that is the case.(directions taken from here)
I had the same issue, yesterday I connected my laptop to the TV and I had to select HDMI Audio output in the Sound Settings menu for having the sound working on TV. This morning I had the HDMI disconnected and the only thing that I had to do for fixing the issue is double clicking in the default audio interface.
I fixed a similar issue just by going into the sound settings & picking the correct audio output device (something like 'inbuilt analog audio' iirc).
I think the problem started when a user fiddled with the volume controls & ended up at the sound menu, then inadvertently clicked on a device option. You can go to sound icon hit mixer and fix from there.
