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
