Sorrry, I can't help. Unfortunatelly you can't understand that if other
players work (i think you tried audio-only players) it doens't mean that
mplayer can work too.

MPlayer has hard code to handle various audio buffering (read
DOCS/tech-eng.txt) so working, correct driver needed.
As linux has 10ms (100Hz) scheduling timer, it is NOT possible to decode
audio fast enough for your very small buffer.

I really can't (and so won't) help with this.
I think that your only chance is asking oss/free driver guys to increase
buffer size in the driver.
