[X2Go-Dev] Bug#546: Some good investigation

[Michael DePaulo]

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.

Check if sound is activated before starting pulse.

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.
