Hi,

using Archlinux, I am not able to get any sound on french h264 dvb channels
with e-ac3 sound using totem.
I have gstreamer-ffmpeg and gstreamer-fluendo modules installed, which seem to
support eac3 decoding ?

I tried to debug using this, I don't known if it is the best way :

 LANG=C gst-launch-0.10 playbin2 uri="dvb://TF1 HD"

What I am missing ?

Thanks,

Paul
