The first behaviour this morning was that mplayer muted after 2-10
seconds this morning
The second behaviour after rebooting the PC was that audio didn't work
because the alsa
device was muted. I do not know if the first one is also somewhat
related to the second behaviour
and pavucontrol might have unmuted it this morning (after closing
pavucontrol sound muted again -
without changing anything in pavucontrol itself).
Whereas the second behaviour is actually known that it might happen
with Ubuntu 9.10
I will do some more experiments when I have some more time for it..
