I'm running vista x86 with version 6213 of the realtek apo driver for the built in realtek sound card on this motherboard (p5n32-sli SE deluxe)..

I had installed the klite mega codec pack at one point.. as well as version 7.3x of PowerDVD.. all was well in the realm of dolby digital (via coax) and Vista.. i could goto the sounds section of control panel and click on the dolby digital check box and do a test.. my receiver showed Dolby Digital.. I also could select spdif in PowerDVD and get dolby digital working fine there as well..

Now suddenly, i cant get it to work.. its gone from powerdvd and if i do the test tones section in control panel i get:

"windows was unable to play the test tone"

The only thought i have, is that coax/dolby digital broke after installing SP1 ? Though i'm not positve.

I'm at a loss.. i've tried removing the 6213 driver completely and reinstalling.. i've tried other versions of the driver.. i've also tried reinstalling the codec pack..

I'm not sure if this error message is related to the driver or a codec issue?

One thing i did notice.. if i switched user accounts.. logged in.. for a split second the test actually worked.. then suddenly it stopped, perhaps after loading things.. I tried killing every task in taskman that i thought could be causing an issue, but nothing fixed it..

Any thoughts?

Thanks
