[MPlayer-users] 5.1 still only played in stereo? (DTS)

[Matthias Hataj]

I'm trying to feed my DTS/DD-Decoder from my musicserver with DTS or  
DD5.1 soundfiles using Toslink.
My FM801 is up and running Alsa 1.09b and everything stereo works fine.
Trying to play one of these swedish testfiles with mplayer decodes it  
to stereo pcm and plays it really lazy:

It looks like it plays a 44,1khz 2ch audio, so no dts and no surround.

so, forcing it to use hwdts s/pdif passthrough leads to this output  
without any sound:
