Some context: I just upgraded from Ubuntu 11.10 to 12.04, or rather reinstalled it, because I formatted the partitions and I made a separated one for /home. I backed up /home, and after installing Precise, I copied the /home backup to its partition.
Now then. I've got sound and I can regulate the volume by typing 'alsamixer' in terminal, but, since my volume indicator didn't work, even after installing PulseAudio Volume Control, which said Connection to PulseAudio failed. Automatic retry in 5s.; Sound in System settings didn't show any hardware, and I don't have Privative Drivers to install, I took the risk of doing 'aptitude purge pulseaudio' - 'aptitude install pulseaudio'. Now I don't even have the useless volume indicator, and to adjust the volume I've got to keep typing 'alsamixer'.
When I type 'pulseaudio' in terminal, it gives me E: [pulseaudio] core-util.c: Home directory /home/USUARIO not ours.
I commented about the /home backup because I also thought it could have been a settings file I shouldn't back up, but I don't know.
¿Any ideas?
