Description Bartosz Kulicki 2005-09-03 04:34:07 UTC

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.

It was tested on 2.6.12 (+ xbox patches) alsa 1.0.9b(+xbox patch) and attached
/etc/asound.conf

Reproducible: Always
Steps to Reproduce:
1. run mplayer -ao alsa -ac hwac3 movie_with_ac3sound.avi
2.
3.

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

Comment 4 Bartosz Kulicki 2005-09-05 01:32:05 UTC

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?

Comment 7 Bartosz Kulicki 2006-07-14 10:56:04 UTC

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.
