I'm now stuck to 2ch ac3 only.
Forced audio codec: hwac3
Opening audio decoder: [hwac3] AC3 pass-through SP/DIF
No accelerated IMDCT transform found
AUDIO: 48000 Hz, 2 ch, 16 bit (0x400), ratio: 56000->192000 (448.0 kbit)
Selected audio codec: [hwac3] afm:hwac3 (AC3 through SPDIF)
alsa-init: testing and bugreports are welcome.
alsa-init: requested format: 48000 Hz, 2 channels, AC3
alsa-init: soundcard set to iec958:AES0=0x2,AES1=0x82,AES2=0x0,AES3=0x2

AO: [alsa9] 48000Hz 2ch AC3
Building audio filter chain for 48000Hz/2ch/16bit -> 48000Hz/2ch/8bit...

Couldn't find matching filter / ao format!
Above is the audio output from mplayer -ao alsa9 -abs 1 -ac hwac3
