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.
