Everything was working great about 3 hours ago on my maverick machine.
Then my clumsy fingers typed
chown -R someuser:somegroup .*, and before I had noticed the dot, I hit enter, and BAM, half my system was owned by someuser before I could stop it.
Needless to say, after much banging of head against wall, I managed to chown everything back to root (namely, /sbin, /etc, /lib, and some stuff under /usr). I
apt-get --reinstall installed a pile of packages, including ALSA. Unfortunately, now, ALSA doesn't work for non-root users. That is,
sudo aplay /usr/share/sounds/alsa/Noise.wav works fine, but as an unprivileged user, it spits out
"cannot find card '0'". Although adding my users to the audio group might work, I'd read many places that this is no longer the solution to these problems.
So that leaves me with the question - where should I look to find my hosed permissions?
