Walid,

something seems to be wrong with your DE setup.

I must admit, I was confused as well - I believed local and remote
volume controls are totally independent; they are not.

The way I tested things was:
- Boot TC.
- Log in on TC console as user, become root
- apt-get update && apt-get install alsa-utils on TC
- run alsamixer on TC -> Notice how both Master and PCM are at 0.
- chvt 7
- Log in to an X2Go session -> Notice how startup sound plays
- switch back to console where alsamixer runs
  -> Notice Master is now at 100
  -> Notice PCM is at the same value as set inside X2Go session
- Move the volume slider in the X2Go session up and down
  -> Notice PCM volume in alsamixer move along
- Disconnect and reconnect session
  -> Notice volume slider in X2Go session is at the value that was
     last set
  -> same goes for terminating the session and starting a new one
  -> same goes for rebooting the TC before reconnecting

So, whatever volume setting I choose in the X2Go session *is* saved and
restored upon reconnect, because the DE I chose (Trinity) is behaving
correctly.

Seems to be a bug with your particular DE, not with X2Go.
