Hi Alex,
it seems we'll need to fall back to PulseAudio 0.9.6 as an intermediate measure. Please provide an updated package.
Further testing with the latest releases of X2Go Client for Windows revealed an audio bug that we have been unable to examine closer. It manifests itself as choppy audio when using Adobe Flash (YouTube etc.).
The latest non-affected client version that I can find on my systems is 3.99.2.0, which comes with PulseAudio 0.9.6. Strangely, I cannot find this release on http://code.x2go.org/releases/binary-win32/x2goclient/ any more.
Mihai and I tried to narrow down the issue, but so far, it looks like we're not getting anywhere. There's a test matrix at http://www.x2go.org/doku.php/doc:bugs:pulsetestmatrix?s[]=pulse that shows which combinations we tried.
Adobe Flash (die! die! die!) seems to be the only application that is negatively affected by the newer PulseAudio release, however, as a lot of multimedia content on the web is still using Adobe Flash, we cannot simply ignore this issue.
A while ago, Mihai also posted this issue to the PulseAudio mailing list (http://lists.freedesktop.org/archives/pulseaudio-discuss/2012-June/013844.ht...), but nobody replied there.
So until we can get the attention of the PulseAudio devs, falling back to PulseAudio 0.9.6 seems to be the only option we have if we want to be able to support multimedia web content.

I have clicks and scratches with the sample files, as well. However, I
run them in Iceweasel 13.0.1 (Debian squeeze, backported). And I run
them locally, not through X2Go.
Are you guys sure that it is related to X2Go at all? On my system, I
have PA 0.9.21-3+squeeze1 (as in Debian squeeze).
Greets, Mike

Please see the test matrix linked in my original message. Our tests included Iceweasel 3.5.16-16 and 13.0.1-1.
This is Iceweasel 13.0.1 on the server, and X2Go with PA 0.9.6 on the Windows client: http://ionic.de/x2go/bugs/pulse/player/playfile.php?file=Win7Ionic-RTestSys1...
- at about 0:30, there's a short "hiccup" as this was a WAN connection, but that's about it.
Same setup, only with PA 1.1 from the newer X2Go Windows client: http://ionic.de/x2go/bugs/pulse/player/playfile.php?file=Win7Ionic-RTestSys1...
- three to four "clicks" per second, absolutely unusable. :-(

Our testing seems to indicate that it is an issue with PulseAudio 1.1, which is shipped with X2Go's Windows client. I think you should test it on a Windows system if you want to experience it for yourself, since that's where we're seeing the issue. Testing with a Linux client will just add another unknown factor to the equation, especially as there are multiple ways of configuring sound output under linux, as opposed to The One Microsoft Way(tm).
