Hash: SHA1

Package: x2goclient
Version: 4.0.3.1

Situation:

Hardware:

Windows Server 2012, installed as Terminal Server
Debian Linux 7.8( Wheezy), installed as X2Go Server
Windows 7x64 Client


Connection scenario:

0) Windows 7 Client tries to play a local sound file.
   Result: Sound works just fine.

1) Windows 7 Client connects to Debian Linux 7.8 using X2GoClient.
   Result: Sound works just fine.

2) Windows 7 Client connects to Windows Server 2012 using RDP
   (mstsc.exe). *NOT* via X2Go's RDP proxy feature.
   Result: Sound works just fine.

3) Windows 7 Client, connected to Windows Server 2012 using RDP
   (mstsc.exe), again, *NOT* via X2Go's RDP proxy feature, tries to run
   X2GoClient *on the Windows Server 2012* *inside* the native RDP
   Session.
   Result: Sound fails for all things X2Go.

Analysis:

It seems that PulseAudio dies as soon as one tries to play sound.

The following are captures of the tasks running on the W2K12 server.


x2goclient running, no attempt to play a sound has been made:

As you can see, pulseaudio.exe is gone.

I can see that this is a rather unusual use case, but still, I'd be
interested to know why PulseAudio fails us here.
