missing sound-volume-applet

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?

Install the indicator-sound package which provides the normal ubuntu volumecontrol via the command

sudo apt-get install indicator-sound

and to make the change take effect do

killall unity-panel-service

Yet another variant (how I solved this problem): Go to dconf-editor (it's graphical settings editor for Gnmoe and Unity, maybe you need to install it first), there go to com->canonical->indicator->sound and check "visible". In my case it just turned to false after one update.

Steps:

1. sudo apt-get install dconf-editor
2. dconf-editor
3. com->canonical->indicator->sound and check visible
