[X2Go-Dev] [pulseaudio] main.c: User-configured server at localhost:, refusing to start/autospawn.

[Mike DePaulo]

Hi Robert,

Whether this is a bug in x2go or an issue with x2go interacts with
PulseAudio, please a file bug with our bug tracker.

I have some comments I would like to add, and I will mention them there.

Also, the high CPU usage may be a separate issue.
