dxva enabled causes audio loss/stutter over spdif out

[GbrNole]

alright been having serious audio probs the past 2 days on a system that prior to installing and removing too many things to list was working perfectly - damn me!!!!!

anyway i have isolated that any video codec that allows dxva to be enabled will now not allow me to properly pass audio over spdif (haven't checked analog outs nor do i really want to)

it's not a sage problem as it does this in the powerDVD player too and as soon as i disable dxva the audio then plays fine.

i guess i can live with this compromise for the time being but sage video doesn't look as good (to me) with dxva disabled for live tv but it does look great in dvd playback.

any ideas how i can fix my not being able to use dxva? anything maybe in the radeon settings that needs to be turned off - fast writes or something?

thanks, nick.

Have you tried downloading the latest DX9 from microsoft ? might solve it. Troubleshooting these kind of issues can be very frustrating.
run DXDIAG from the run command and check for any problems in each tab, you can test each element as well.
also you could try re-installing the audio drivers for your MB, check the IRQ's interupt, my guess is is the analog is messed up too, so thats really where I would start, that would tell you if its just the SPDIF or its a more general audio problem.

turning off video card settings would be a last resort, I would stick to defaut at first, You might want to select "fail safe" on your MB or even drain the CMOS on it.
