The short story is that while playing many different games, the audio will suddenly develop a horrid popping reverb that will last for awhile (ten to fifteen minutes usually) and eventually go away. I've had this happen with: Diablo3 (pretty consistently), Civ5, Borderlands2, and basically everything I've played lately. With the DPC Latency Checker running on the second monitor everything is green, around the 80us range until the problem occurs. As soon as the problem starts, the bars go solid red, to the top of the window ( > 16000us) and stay there until it stops happening. As soon as the audio returns to normal, the red lines instantly drop away and it goes back to the 80us green range. If I start xperf running after it redlines, the summary charts aren't that helpful. Nothing has a Max duration above 0.04, and all the avg durations are around 0.002. I'm going to run another test in a bit with xperf running the whole time, and I'll return with more info. Now for the system details: OS: Windows 7, 64 MB: Gigabyte GA-X58-UD5 (GIGABYTE - Motherboard - Socket 1366 - GA-X58A-UD5 (rev. 2.0)) Sound: Onboard Realtek Video: HD5870 (two monitors attached to this card) Until this morning I had a SB X-Fi in the machine, with the Realtek disabled in the device manager. I yanked the SB out and turned the Realtek Audio on and the problem still occurred. I've disabled a bunch of devices (and left them disabled) and the problem still occurs. I'm down to hard drive controllers and things like that which I'm hesitant to disable.
