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.html), 
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.
