Everything was working great about 3 hours ago on my maverick machine.Then an issue cropped up.
I ran the command chown -R someuser:somegroup .*
, and before I had noticed the .
, I hit Enter, and this mistake made that half my system was owned by someuser
before I could stop it.
I managed to get everything back to root (namely, /sbin
, /etc
, /lib
, and some stuff under /usr
). I apt-get --reinstall install
ed a pile of packages, including ALSA.
Unfortunately, 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?
