ubuntu 11.10
I recently changed unity for classic Desktop. So, i noticed that the volume control dissappeared.
So i read everywhere that the only thing to do is add the Inidicator Applet in the panel. But i dont have that option in my applet list.

You want the the option from the list to add an "Indicator Applet".
This is because from Ubuntu 10.04 there has been a push for panel items to use a new system for panel items.
If adding the "Indicator Applet" appears to make no difference, you should try to install the package indicator-sound which contains the sound indicator.
WebUpd8 covered this - I've tested this on oneiric and it does work.
It requires an indicator from a PPA together with some additional scripts:
sudo add-apt-repository ppa:alexeftimie/ppa
sudo apt-get update
sudo apt-get install indicator-sysmonitor dstat
mkdir -p ~/scripts && cd ~/scripts
wget http://webupd8.googlecode.com/files/sysmon_0.2.tar.gz && tar -xvf sysmon_0.2.tar.gz
Start the indicator
indicator-sysmonitor &
Then in the indicator-preferences:
click "use this command" and copy and paste the following text:
$HOME/scripts/sysmon

The indicator applet has not been ported to GNOME 3 and GTK3 yet. This is required for it to work in Ubuntu 11.10. There is currenly a bug tracking it.
