[X2Go-User] Audio device selection

[karel]

I have X2go server at Ubuntu 12.04 and client at Windows7, both the
latest version. Where and how I can set which of my audio devices is
used by x2go client (pulseaudio)? At the moment it will use
defaultdevice (and will follow the change) but I would like to fix it
to another. In client settings there is no such place and in server
there is PulseAudio Volume Control where I will see only the same
default device.
