1. This bug was introduced by 1 of these 2 closely related back-to-back commits:

Don't start pulse on Windows, until we have not session with pulse support. b9f981d979ab22db4d078c398ecc420f73a46f8c http://code.x2go.org/gitweb?p=x2goclient.git;a=commit;h=b9f981d979ab22db4d07...

Check if sound is activated before starting pulse. 1a07416622d25006c6458369c135124f63845a71 http://code.x2go.org/gitweb?p=x2goclient.git;a=commit;h=1a07416622d25006c645...

2. If a start a session, log out of the session gracefully, and then start that session again: The pulseaudio.exe process stays running after the 1st session ends, and this bug does not occur.

3. If I do what I originally mentioned to produce this bug: The pulseaudio process is ended after I disconnect, and then a new one is started for when I go to reconnect. (And this bug is triggered.)

4. Sometimes I am unable to reproduce this bug. I think that if you start a session, end that session gracefully, start that session again, disconnect, and then reconnect, then this bug does not occur. I did not investigate this fully.
