​Hi,
I have installed the current x2go-client (4.1.2.0) on two Windows computers. Under Win7 the sound works fine. Not under Windows 10, because the program PulseAudio does not start! When starting the program on the command line, these messages appear:

Even in compatibility mode (win 7) PulseAudio cannot be started and I did not find a more current version for Windows on the web.
