[MPlayer-users] AC3 with mplayer/alsa on SB Live! 5.1

I am trying to play the AC3 (5.1) audio stream of a DVD with
MPlayer-1.0pre5, ALSA (kernel, and a SB Live! 5.1 (snd-emu10k1)
via SPDIF on a DTT2500.

After a LONG time experimenting I got it to work with my boards built-in
AMD-8111 AC97 Audio (snd-intel8x0) using the following command line:
  mplayer -ac=hwac3 -ao=alsa -format=1024 dvd://1

Attempting to use the same command line with my SB Live! card does
however fail with the following error:
  ALSA lib pcm_hw.c:1155:(snd_pcm_hw_open) open /dev/snd/pcmC0D2p
  failed: No such device
Now I am not sure whether this is caused by 
- mplayer using a hardcoded device value of
  "iec958:AES0=0x2,AES1=0x82,AES2=0x0,AES3=0x2" for hwac3 output
- the alsa library attempting to open /dev/snd/pcmC0D2p with the emu10k1
  instead of /dev/snd/pcmC0D0p as with the intel8x0 driver
- the emu10k1 driver not prividing the /dev/snd/pcmC0D2p interface
