Re: pulseaudio causing crashing of applications



Right, I'm having fun with PA not working and having to log out and in
to get it up and running again.  For reasons I can't explain, PA just
stops responding.  This can be seen in a number of ways:

The sound on VMWare Player complains that /dev/snd (I think) isn't
available.

Rhythmbox will seem to work fine, but any attempt to play a file results
in no sound and the time-line indicator doesn't move from the start (or
actually, it starts to move and then goes back to the start).

Sounds from various applications don't play.

So, I'm intersted in this so I can try to debug this and provide useful
information for resolving this issue.

I tried running pactl, but get this:

[rodd localhost ~]$ pactl 
No valid command specified.

I then tried

[rodd localhost ~]$ pactl list-sinks
No valid command specified.

Finally I did a check of man pactl and then tried 'pactl list' but this
gives a huge output, only some of which is 'sinks'.

How would I tell what state my sound card is in (currently it's working,
but I wanted to try all this while everything worked so I could see
what's changed.)
