Adding to the replies so far, we have the infrastructure to support
these formats in PulseAudio (v1.0 onwards). However, we only support AC3
(Dolby Digital), E-AC3 (Dolby Digital Plus) DTS and MP3 at the moment.
This is mostly because these are the only ones anyone has gotten around
to being able to test.

Support for these formats is in VLC 1.1.12 and 1.2 if I remember
correctly, and should  available in the next release of GStreamer (=>
Totem, etc. will also be able to support it).

You need to explicitly specify what formats your receiver supports at
the moment, which can be done with recent pavucontrol or in the command
line using 'pactl set-sink-formats'.

Cheers,
Arun
