That's not really something we want to do, because the volume we talk abo= ut here is a client-side setting. In a simple setup where only one client machine ever connects to one sess= ion, and that client machine never changes, that might work, but in any more complicated setup it's a recipe for doom. Further, given that I know your setup a little bit, saving or restoring s= ettings would not work as expected when for instance additional headsets are *not= * plugged in while the session is established but later on. x2ogcleansessions is a totally wrong approach for stuff like that, becaus= e saving the settings must be done while the client is still connected (sin= ce we need to access the client-side PA daemon.) If anything, you could use x2goserver's hooks infrastructure, but I'm not= sure in what context these scripts are executed. If it's any context that does= n't inherit environment variables from the client, that's not going to work. = The pre-suspend/pre-terminate and post-resume/post-scripts hooks (check /usr/lib/x2go/extensions) might be promising places for something like th= at. Again, as a general feature that's probably causing more trouble than it'= s worth, especially when using multiple sessions at a time or when changing= client-side stuff.
