Playing a film with sound enabled on Totem gives the following error on the console:
** Message: Error: Internal data stream error.
gstoggdemux.c(4467): gst_ogg_demux_loop (): /GstPlayBin2:play/GstURIDecodeBin:uridecodebin0/GstDecodeBin2:decodebin20/GstOggDemux:oggdemux0:
stream stopped, reason not-negotiated
And also a popup saying "Internal data stream error".
We have a known incompatibility between our pulseaudio and modern pulseaudio client libs. It's probably the cause here as well.
Looks like this has been fixed with bug #3222. Closing.
Looks good on Ubuntu 12.10 as well. Closing.
