[MPlayer-users] cannot find simple control PCM

[peng shao]

Hi dear all. I have an M-audio 24/96 sound(ICE1712 chipset) card on my
machine. I just compiled
MPlayer SVN-r28737-4.1.2 (C) 2000-2009 MPlayer Team

However, i found that when I was trying to open any media file by gmplayer,
I got constantly error message
[AO_ALSA] Unable to find simple control 'PCM',0.
on my screen. But mplayer was working pretty well.

I do not know what I should use as alsa_mixer_channel, I tried PCM Out,
Front, balbalaba. but none of them worked....

I know this is a typical problem and most of the suggestions I found through
google is to choose oss or pulse instead.
But I perfer alsa:( So is there anybody who met similar problem and know how
to solve it?

Thank you for your concern~~
