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?
