[X2Go-User] Pulseaudio doesn't start on Win7

[Ralf]

Hello list, greetings!

I have the following setup runing:
A docker-container providing a rudimental desktop (fluxbox on debian)
A Win7PC which gets the desktop using x2Go.

All is working as expected but the pulseaudio server on the win7-client 
doesn't start automatically.
If I use an external pulseaudio.exe with an lightly modified default.pa 
the pulseaudio-sever starts.
After that "trick" I have to edit .pulse-client.conf in my 
docker-container for sending audio to my win7-pulseserver and it will 
work.
The drawback is: I cannot use the ssh-tunnel from x2go for the audio 
... it is not established cause of the missing port of the not startet 
"internal" pulseserver.

Is there a chance to give an modified default.pa to the "internal" 
pulseaudio-server of the x2go-client or even better: is it possible to 
use an "external" pulseaudio.exe with the x2go-client?

The next "problem" for an automated workaround (starting pulseaudio 
with script prior to the x2go-client) is, that the x2go-client seems to 
use port 4714 for untunneled connections. Does someone now the parameter 
for changing the pulseaudio-serverport from 4713 to 4714 for the 
pulse-audio-windows-version 1.1? This is the most "dirty" hack ... but 
should do the work in this case. The other way round is of course 
although possible: change the port the x2go-client expects his 
"internal" server. This way the .pulse-client.conf in the docker-desktop 
would be build correct for this szenario.

Maye someone point me the direction?

Uhhh ... its long ago I have written text in english

Have a nice day!!
