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 only use WMP since it's the only player I've ever used with this pc.
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.
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.
