Not certain this is the correct forum, but:
Windows XP Home Edition Service Pack 3
ATI Function Driver for High Definition Audio - ATI AA01
Realtek High Definition Audio
Same issue, two places -
1. I connect to the www via Verizon's VZAccess Manager (aircard); when the Manager opens, a VERY LOUD, obnoxious percussive electronic sound happens (can hardly call it a tone or a beep); Manager's options/settings has nothing related to it; Verizon tech says they've never heard of such before and it has nothing to do with their aircard.
2. The "master" volume control for my PC seems to be RealTek HD Audio Manager volume control (don't really understand how sometimes things show up on my PC; for example, on an older Windows OS, don't remember which -- there have been SO MANY wonderful versions since I was a kid (!), there apparently was a "master volume" control of some sort imbedded in the Windows program, so that was what I'd use...XP hasn't offered that up that I've seen; I've concluded that now RealTek's program provides that function); whenever I move the volume slider up or down, the VERY LOUD sound happens here too -- only in this case it's a distinctive "beep" (or, should say "BEEEEEP!!!!!)
The only operational difference I've been able to sniff out is that when I removed RealTek from the system, these noises/sounds ceased to exist; reloaded RealTek, and they returned.
Any suggestions on how to remove these two irritating intrusions into my cyberlife?
