Yesterday morning I woke up to discover that my computer's audio suddenly possessed a strange scratchy sound. I leave my computer on 24/7 and had watched a movie on it the night before, so the distortion came as some surprise to me. The distortion is definitely coming from the computer itself, as it remains even when I change the speakers. I'm pretty sure it's not a problem of codecs, because I installed new codecs and the distortion didn't change, and furthermore it's present in every sound the computer plays, from the CHIMES that accompany Windows XP opening to the sound from internet video like youtube and it's even present in in-game audio on Dawn of War. This seems to indicate that it's a problem with the card itself (I have SigmaTel integrated card). It's not a problem with the port, as the scratch is present on both the inputs in the back and the headphone input in front. I tried reinstalling the drivers, and here is where the really weird part starts. I went to Dell's website and put in my serial NUMBER and it came up with my system specs and the original drivers for all my hardware. When I downloaded the audio driver and tried to install it, it gave me an error message and SAID that "this is not the correct audio driver for this system."

Right now I'm ready to buy a new soundblaster USB card, but I thought I might as well check and see if anyone could save me 60 bucks with any suggestions of how to fix things.If you have a on board sound [you should] i would uninstall your present card and try using the on board as a testAs I understand it, onboard sound is what I'm currently using.You're not alone with that problem: See Here...

So I searched this "Intel 82801GB ICH7 - High Definition Audio Controller [A-1]" which brought me here http://cr.am/framed.php?url=http%3A%2F%2Fdownloadcenter.intel.com%2Ffilter_results.aspx%3FstrTypes%3Dall%26ProductID%3D2068%26OSFullName%3DWindows*%2BXP%2BProfessional%26lang%3Deng%26strOSs%3D44%26submit%3DGo%2521&ref=driverguide

So i downloaded that driver, installed it, and got to the end before I got an error that said "_Exiterror:error=device object not present, restart the system and run setup again." In the course of installing, I got a "found new hardware" popup that said it found my HD Audio Hub. So I restarted, and the new hardware popup came again on restart. I opened Itunes, and my sound seems to work fine now. However, I tried running that driver install again, and got the same message telling me to restart. I'm tempted to leave it as it is for now, but any advice?Try Intel site: http://downloadcenter.intel.com/default.aspx, #7That driver worked. Thanks a bunch for the help.Yes!!
