Ah, I fix it.

1. I install OSS and install MPLayer.
2. Then I switch to ALSA and not recompile MPlayer, so have this error. 
( 7 channels are not supported )
3. Then I just recompile MPlayer with ALSA installed, and problem 
resolved :)

MPlayer must be compile with current sound drivers.
I think, problem in `soundcard.h` file.

IMHO MPlayer should note users, that problem can be in sound drivers, 
when it can't switch to `n` channels support.

But little problem is still.
I hear some damage sound like noise. MPlayer didn't support AOB?

With VLC I have no problem ( when I playback from DVD ).
