No sound for non-root users
The sound has stopped working for regular, non-root users on my
installation of Debian Etch (on a Dell PC with integrated Intel audio
chipset).
Sound still works for root (or using sudo), but when I try to run an
audio program as an ordinary user (eg mplayer, alsamixer), I get an
error saying, "No such device" or similar. All users are members of the
"audio" group.
The problem started the first time the PC was rebooted after I installed
some missing packages for XFCE this afternoon. Here is the aptitude log
for the session in which I installed XFCE, in case it's relevant:
