For some reason my Winamp volume started moving up and down. I'm not doing anything on my system and I'll hear it get lower then increase. It had been working fine and all of a sudden changed without me doing anything. I'm using Winamp 5.0rc8 11/19/03. I've got a SB Audigy 2 ZS. I've tried the newest version of Winamp as well and it still didn't work.
