[blast and bother]

I recently installed windows vista 64 and now i cannot get digital sound output. On board sound Asus m2n4sli mobo realtek ac97 driver. Windows shows it working but its not coming out of jack. I have installled all the vista 64 drivers from realtek including the beta drivers only to find that none of them show as digitally signed - seems odd, as vista requires signed drivers, that realtek would offer unsigned drivers for vista. Anyone out there in the big wide world know where i can get a digitally signed driver?
On the graphics front I have two nvidia8600gt's again downloaded latest drivers but I cannot get them to work in sli config - in fact cannot find option to select sli . When looking in device manager it says not enough resources for second card code 12 , i have 5 gb ram, what do they mean by resources? - After much research i have found that there are no drivers out there to support sli on vista 64 as yet.

I'm not familier with the software accompanied by the ac97 however you would need to specify the digital output. See if you can't find an option that that may say 'digitial IO' this usually will enable a digital output rather than analog.

checking playback devices it says Realtek digital output : realtek ac'97 audio working but it clearly isn't. I have set this to default. I cannot find any other way to select digital out.

system:
amd 64X2 4200
Asus m2n4 sli nforce 4 mobo
2Xnvidia 8600gt 512mb graphics cards (cant get both of these to run sli either)
120Gb hdd

Another curiosity i may add is after reinstalling realtek driver i re boot and get 3/4 of startup sound then nothing forever more . ??????

I just deleted all my nvidia driver downloads and uninstalled active drivers and to my surprise i got sound back. So I now have a choice sound or vision.
