Okay, sound problem confirmed!!

I did not notice the problem at first based on my game preferences. All the Source based games run fine. Most older titles do as well. However, as soon as BF2 went in (and BF 2142) the problem occured. Then a few more late games like Dark Mesiah and COH.

And, the problem IS seriously nasty. We aren't talking about a little cracking and popping here, but a nasty full on crackle, hiss, pop, and screech that renders the system totally un playable.

The only fix is to disable SLI. PCI latency tools do nothing. All latest available drivers and BIOS do not help. All combinations of Windows Updates for HD sound and SP2 fixes do not help either.

Optical cable helps...but only a little. Still un playable.

The problem configurations are any 8800s in SLI with any sound solution. Whether its X-fi, Turtle Beach, or on board sound, the problem is there. Surprisingly, on board sound is the WORST.

What I want to know is how in the hell did Nvidia and its partners miss this issue? Shocking to say the least.

Sorry I don't have more benches of my 24/7 rig right now, but I am now full time trying to resolve this sound issue.

Anyone considering 680i + 8800 SLI for any gaming beware.
