I have a Pioneer DVD-115 dvdrom that was working, which i have already flashed once (2 months ago). everything was cool, then i noticed another firmware upgrade. so i successfully flash it again (bios recognizes firmware change, and the flash program itself says success). but problem now is that when i try to play an audio cd, all i get is a constant grating, like a saw or something. ive tried a number of older cds, so its not a copy protection issue. funny thing is i can play MP#s with winamp off of a cd that i burned last year, just the .cda files dont play. i have winxp, and have enabled/disabled "digital audio" in device manager. any ideas?
