It is definitely tied to alsa, as oss which is running on top of alsa 
works fine, no desyncs.  So there seems to be some sort of buffer issue 
with the alsa driver. 

my card is :

 0 [CK804          ]: NFORCE - NVidia CK804
                      NVidia CK804 with ALC850 at 0xc8103000, irq 225

This is an nforce4 onboard chipset from the Asus A8N-E.

Though, it's probably not card specific, since aoss works without any av 
sync issues.  Seems that the alsa driver needs some fine tuning in 
mplayer. 

If any further info is needed i'd be more than happy to give it.
