volume turns itself down

[twelter]

About every 10-15 minutes, the volume (the little speaker on my bottom toolbar) slides to the bottom, not mute, but turned all the way down. I have checked technical support with Winamp, Soundblaster and Microsoft and tried all the various fixes. It only does this when I am in WinAmp. I have tried disabling the volume control in Winamp preferences but doesn't make any difference. I just downloaded the latest WinAmp about 3 weeks ago. I use Soundblaster 5.1 and have the latest driver, I read the support about removing a certain soundblaster file but don't see it loaded on the Winamp recent version. I have XP and have scanned for all viruses,spyware, etc. I also have soundblaster listed on the output under Direct Sound output. Any suggestions other than what Dell suggested, reinstalling Windows? Thank you.
