I turn on my PC and wait for it to get to the desktop, it plays the start windows sound and will continue to play sounds for approx. 45 seconds after boot. If i start a program that has sound (ie, powerDVD, spider solitaire, etc.) it will play sounds for that program after the 45 second delay. If i close said prog, so goes sound. However, it still plays sounds with winamp, and also plays the menu command sound (i have it set to the balloon help noise :freak: ). Any sound played via other means is usually fruitless. I have un-installed/ re-installed the drivers and hardware to no avail. The drivers are up to date. The 'sounds and audio devices' control panel applet reports "no audio device" and device manager reports no problems with hardware. Also checked startup items and found nothing unusual.
I've got a feeling its registry related but don't know where to look.
Any suggestions would be helpful.
