</div>Make sure you have the patches applied in your pulseaudio and gstreamer<br>
that are talked about in this thread:<br>
<a href="http://lists.freedesktop.org/archives/pulseaudio-discuss/2011-June/010305.html" target="_blank">http://lists.freedesktop.org/archives/pulseaudio-discuss/2011-June/010305.html</a><br>
<br>
If you already have those, I don't have any further hints.<br>
