Please describe the problem:
Banshee doesn't recognise multichannel files (like: 5.1 mp3, 5.1 mp4-aac, 5.1
dts-wav, 5.1 ac3), and if it does (for example 5.1-mp3) than it's playing it only in stereo.

Sample multichannel files:
MP3: http://www.all4mp3.com/music/
MP3:
ftp://ftp.tnt.uni-hannover.de/pub/MPEG/audio/mpeg2/compliance/testdata/test23.tar.gz
DTS: http://www.sr.se/cgi-bin/mall/index.asp?programid=2445


Steps to reproduce:
1. Download sample file
2. Open Banshee
3. Import sample file
4. Play sample file


Actual results:
By most of them (especially mp4), banshee dosn't import the files.
Otherwise it's playing it in stereo only.


Expected results:
Let's always import the file and an option to playing it in stereo or multichannel (one could be default).


Does this happen every time?
Yes, it happens every time.


Other information:
I would like to see an option (like in vlc for example) for how may channels i
would like to listen (1.0 mono, 2.0 stereo, 2.1, 4.0, 4.1, 5.0, 5.1
multichannel). The default playback channel could be recognised from the file
(5.1 files at 5.1 channels) or always stereo (downmix), but add an option to
listen the multichannel file in multichannel surround.
Most of the files can be played in vlc or mplayer with full multichannel
surround.
