For now I believe I have it fixed (crosses fingers!) here's the original topic: http://www.gameex.info/forums/topic/13431-kega-fusion-and-daemon-tools-lite-cd-audio-is-no-longer-working/#entry109844 and I just realized I forgot my Memory specs (Kingston 2400 memory at 2133) in my specs. Thanks to Adultry and Draco1962, nullPointer and DJoneK for their help back then. I didn't want to necropost or bump an almost two month old topic. I gave up for a bit due to the fact I've been REALLY busy with work (long story), been focusing on game collecting for the PS1 when I can, spending time with my girlfriend when I can among other things. But now I wanna get back to enjoying my media/emulation computer and I think I found the problem - it was my PCI-E soundcard. I got thinking about it the other day so this morning I took it out it from the computer and removed the drivers as well and right now it's actually working really well. Like I said, it only affected Sega CD games with Dameon Tools/Kega Fusion and the CD audio would start out sounding good then after two-three seconds get really stuttery and scratchy. The main game I used to test was After Burner III and Ninja Warriors, The (Japanese release) and I think I even had the same issue with .bin/.cue games too. Other disc based games (PS1, Saturn etc) were not affected. I think having three audio devices (graphics card HDMI audio, onboard audio and the PCI-E Soundcard) were all acting up. I even reformatted but after a while it started acting up. But now I think I got it fixed. Phew!
