Description Luigi Maselli 2007-03-06 22:18:02 UTC 
Please describe the problem:
I don't know if it is a gstreamer or totem bug, but I can't play correctly AC3 (5.1 channels) via SPDIF because the output remains in stereo(2.0)

Test files:
ed2k://|file|demo-dvd-ac3.vob|3821568|2D5621812D8ED7BDACB5401DE1F0BE79|h=K6BZ2AG3VROCCFVMKRKIEAEAFNP4O6Y4|/

I have no problem to play these files with mplayer, with:
$ mplayer file.avi.ac3 -ac hwac3 

Steps to reproduce:
1. open an ac3 5.1 audio/video file
(the file is played in stereo)
2. select ac3 instead of stereo
(the file is played in stereo)

Actual results:


Expected results:


Does this happen every time?

Totem/playbin don't support AC3 passthrough yet (see bug #331875).

In other words: audio is not output over SPDIF.

Whether AC3 is decoded to stereo or 5.1 depends on what your audiosink is capable of (only raw audio sinks like alsasink work though at the moment), at least with current/cvs versions of gst-plugins-ugly/a52dec.
