For no reason that I can discern, the audio on my desktop has decided to go totally out of whack whenever I play a game on it. I thought it was originally a problem with Mass Effect 2 (where I first saw the issue). All sounds coming out of the speakers would be accompanied by various snaps, crackles, and pops, and it sounded like all the voices ingame were being played twice at the same time. In The Elder Scrolls IV: Oblivion, I got the same rice krispies effect as ME2, and the background music was erratic (played superfast and seemed to spontaneously change and reset). When playing Supreme Commander, all I got was some nice screeching and constant tones.
I thought that perhaps it was a problem with programs running in fullscreen, but SupCom did it in window mode as well, and 1602 AD (or Anno 1602, whatever you know it as) didn't have issues in fullscreen mode. The strange part about all of this is that it ONLY seems to affect my games; all Windows sounds play normally, and I can listen to music and watch movies with no audio problems.
I've tried updating the audio drivers, but that had no effect. What REALLY got me was that I completely reformatted the hard drive and put a fresh install of Windows on it, yet after installing Oblivion I still have audio problems. When I check my audio device in Device Manager, it checks out as having no problems (simply disabling/enabling does nothing, either). Given the fact that absolutely nothing changed on my computer for months before this happened, it all leads me to suspect that the integrated sound chip on my mobo is screwed up, but it doesn't make sense that only games are affected, and in very odd and specific ways. Any ideas for what to do about this, short of just buying a new motherboard? Thanks for the help.
