[GStreamer (GNOME Bugzilla)]

I don't know anything about server. I get this stream from my internet provider
and unable to get more information. I can record it with wireshark later, but I
don't know if this helps. Stream converted to http stream using udpxy project
is playing normally. Looks like there is something with combination of
multicast source and audio sink. Using gst-discover I found some differences in
my streams (working and jamming). There is only one difference which is
different for from all streams. This jamming stream has "channel mode:
joint-stereo". Other streams has "channel mode: stereo".

Does this helps? Can you try to reproduce on multicast stream with joint-stereo
channel mode?

Here is gst-discover output for jamming stream:

Please tell me, if you still need pcap dump.
