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.

Please record and send a PulseAudio debug log.

You do not need to be using a debug build to do this:

1. Run x2goclient.exe with --debug
2. Reproduce this problem. You can exit x2goclient when done.
3. Assuming your %USERPROFILE% is C:\Users\mike.DEPAULO, look under
C:\Users\mike.DEPAULO\.x2go\pulse\
4. Sort the subfolders by date. The newest (or only) subfolder will
whose name begins with "tmp" contain the pulse.log file. This is the
droid we're looking for.

It also occurs with x2goclient-4.0.2.0.
It also occurs with x2goclient-4.0.1.2.
It does *not* occur with x2goclient-4.0.0.3.

4.0.0.3 has PulseAudio 0.9.6 and no x2gohelper.exe.
4.0.1.2 has PulseAudio 1.1 and no x2gohelper.exe.
4.0.2.0 has PulseAudio 5 and no x2gohelper.exe.

So I guess we can rule out x2gohelper.exe.

It may indeed be that it is because PA can't find a recording device.
Though what surprises me is that I've seen pulseaudio.exe is running
and running and running ... until I establish a connection.  However,
now, as I try to reproduce it with the older versions, it seems to die
immediately. :confused:
