Thanks Daniel for the fast answer! I did:
sudo add-apt-repository ppa:ubuntu-audio-dev/ppa
sudo apt-get update
sudo apt-get install pulseaudio
...and rebooted. I hope that's correct. Unfortunately that didn't solve
the problem. Just a guess: Does pulseaudio run suid? If so, that might
be a possible cause of the problem: In a root shell (e.g. sudo -s), I
don't have permissions on my home directory because of the kerberos
authentication.
Anyway, just to make sure I didn't do anything wrong, here's the output
of "apt-cache showpkg pulseaudio", followed by an excerpt of strace's
output:
