audio

This one is driving me nuts. Hoping someone can shed some light.

I'm running windows 7 using onboard audio. It's been fine for over 2 years but lately there's a problem every time I play audio.

I hear a small soft burst of static and the volume turns itself down from 50% to 23%. Once at 23%, it plays fine. No related events logged in viewer. No reported problems with the device. Different headphones, same problem. I played around with audio settings for hours but the problem persists.

EDIT: ok more info:

Motherboard: ECS G31T-M LGA775

System info displays this:

Name High Definition Audio Device Manufacturer Microsoft Status OK PNP Device ID HDAUDIO\FUNC_01&VEN_1106&DEV_E721&SUBSYS_10192683&REV_1001\4&3D4E739&0&0001 Driver c:\windows\system32\drivers\hdaudio.sys (6.1.7600.16385, 297.00 KB (304,128 bytes), 14/07/2009 9:51 AM)

I'll keep adding info as I find it.

The question I want resolved is; Is it faulty hardware? If so, I can buy a sound card. I can't imagine software is responsible since I haven't installed anything new for weeks. Virus scans are clear as well. The static burst is irritating to say the least. Tried 2 different headphones and separate speakers. Same problem.

I know it's not an easy problem but I was hoping someone had encountered the same thing.
