mplayer fails when trying to play ac3/dts content on xbox using SPDIF (-hwac3 or -hwdts). It exits with: ALSA lib setup.c:548:(add_elem) Cannot obtain info for CTL elem (MIXER,'IEC958 Playback AC97-SPSA',0,0,0):.... This is due to lack of this control in xbox alsa. Attached patch takes out IEC958 initialization from mplayer code.

I don't know the right syntax or if it works with your version of MPlayer (since you didn't tell us which you are actually using), but why not just mplayer -ao also:device=default
I'm using mplayer-1.0_pre7-r1. I'll try your suggestion in two days as I dont have access to Xbox right now.
alsa issue again?
still an issue with newer versions of mplayer?
it's still an issue with mplayer 1.0_pre8. Attached patch works with this version. This is related to this subarch _only_. XBOX doesn't have hardware mixers (or at least they are not accessible through alsa). In other words it's not mplayer bug per se but a combination of this specific hardware and mplayer.
