I don't have any trouble after removing pulseaudio
Without removing pulseaudio I could never get mplayer to do the
passthrough at all. This script plays DVDs just fine with
audio going out to SP/DIF:
amixer set IEC958 unmute
amixer set 'IEC958 Playback AC97-SPSA' 0
amixer set 'IEC958 Playback Source' PCM
exec mplayer dvd://1 -alang en -ao alsa:device=hw=0.0 -ac hwdts,hwac3, -monitoraspect
16:9 -fs
Then pulseaudio came along, and nothing I tried would get this
script to work again until I tried "yum erase pulseaudio" :-).
Just tried "mplayer -ao alsa -ac hwac3, TRANSFORMERS.iso" and it
picked the right output automatically. I'm running alsa ver. 1.0.19
and pulseaudio ver. 0.9.14. Not that it matters much you can also use
the option -afm hwac3 which will try both AC3 & DTS and you don't need
the "," for fallback.
It may be an ALSA driver issue. I remember having more issues when I
was running nForce boards with AC97 audio. All my new boards are
AMD/ATI chipset with HDA audio and work quite well without much
fiddling.
