I am using ubuntu 12.10. I had some problems with my skype and audio. So I did the following and it's working fine now:
sudo apt-get purge pulseaudio sudo apt-get autoremove sudo reboot
After this I reinstalled pulseaudio via
sudo apt-get install pulseaudio
But now my icon in the gnome-panel is missing. After searching on google I found that that the sound-volume-applet ist missing.
So is this right? And do you get the icon in the panel?
