Hi,
I'm still struggling to make my TCE setup work correctly. I managed to fix about every bits here and there but there is still one important part that I can't get to fix which is managing audio applications to work in TCE mode.
To be clear, what I call "TCE mode" is pxe booting an diskless station with x2gothinclient (per the doc setup with default settings, Debian wheezy based with heuler x2go client)
When I open a X2Go session with a local x2go client on my Ubuntu laptop (or even with x2goclient under windows), no problem, I have sound with PulseAudio fully working, I can play videos on youtube, hear MP3s with totem or any other audio application. Running the same session with a TCE client works great until I want to hear a sound ... youtube videos are hanging with no sound, playing MP3s don't even start. Anything related to PulseAudio seems broken in TCE mode and this is very annoying to me because we'd like to deploy TCEs in my company to replace about 150 Windows PCs but this is for a call center so if audio is not working, this is a no go.
I'm pretty sure this can be fixed with some PulseAudio configuration tuning but I must admit that I'm totally confused by PA and I don't understand a bit of the beast so any help would be gladly welcomed !
Best regards,
Walid MOGHRABI

A few more informations about this bug, here is a snippet from /var/log/syslog taken from the TCE when opening a new X2Go session :
Sep 23 13:51:50 x2gothinclient rtkit-daemon[2629]: Successfully dropped privileges. Sep 23 13:51:50 x2gothinclient rtkit-daemon[2629]: Successfully limited resources.
