Not sure what is going on. I still use an A2zs SC (if matters) kkkkk.....I am dinking around with rigs trying to get Mach2 on a diff build. Pulled mobo on this rig and put a K8N Neo4 in to get things going. Did a fresh install of XP. I put A2zs back in and w/ Creative drivers and I got no sound. I then uninstalled A2 drivers and installed in reg mobo sound drivers (AC97)....still no sound. I also tried diff slots. I only get sound out of the control unit jack with headphones. WTF?
