I was trying to fix a problem a long time ago with my sound by removing alsa/puleaudio and reinstalling things that I didn't understand.
Now my sound is messed up. The volume keys on my keyboard don't work, and I don't get the same sound indicator menu as I used to that had rhythmbox etc in it.
Also, this happens
gnome-volume-control-applet: command not found
I'm very sure this is just a matter of re apt-getting some packages and maybe removing, but I don't know which.
The sound itself does play.
