Re: [alsa-devel] [PATCH]Support MCP89 and GT21x hdmi audio

...

Could you do strace for ALSA ioctls? At least having the error code might help to identify this issue.

I don't know how but I'm willing to try if you want to tell me how to do it. Please keep in mind, I'm just an end-user -- not a developer or even c coder. The most I've done is run xine in gdb to help supply bug info to those devs.

strace -o alsa-strace speaker-test -Dhw:0,3 -t wav -c2 -l1

Or

strace -o alsa-strace mplayer -ao alsa:device=hw=0.3 XXXXXXXX.mp3

Do you see error messages when playing via other audio devices, eg.

mplayer -ao alsa:device=hw=0.0 XXXXXXXX.mp3

?
