well i seemed to have fixed my problem for now... i used my old cd for motherboard that had my audio (realtek) drivers
on there. Old cd, old version of realtek, file version 2.1.5 :eek but its working ... compat mode vista
maybe try using older drivers (cd) with comp mode vista?
version 188.8.131.5210 installed with audio codec ALC850
Reports nvidia audio controller(0059) ... maybe this could be the conflict with many of us....
