Maybe a simple question, but is it possible to
play a 6 channel wav file over a spdif connection?
$aplay -L
...
iec958:CARD=Audigy2,DEV=0
Audigy 2 ZS [2001], ADC Capture/Standard PCM Playback
IEC958 (S/PDIF) Digital Audio Output
...
sample file

$aplay -D iec958 chan-id.wav
Playing WAVE 'chan-id.wav' : Signed 16 bit Little Endian, Rate 44100 Hz,

$mplayer chan-id.wav -ao alsa:device=spdif -channels 6

aplay refuse to play the file while mplayer downmix the file and will
only play the front left and right channels
Any dts or dolby digital dvd will play fine with mplayer -ao
alsa:device=spdif -afm hwac3.
