I recently moved from an AMD K6-266 to an AMD 3D-300 on an Alton (PCChips?) motherboard with soundpro. The sound is fine. The Mitsumi 32X CD reads data fine and plays music during installation routines. The problem is that anytime CDPlayer is accessed, the system freezes. It will not play a music CD. I had no problem before switching to the 3D chip. Can anyone help me. I've been trying for 2 weeks to get the vendor to answer email or return a phone call with no luck. Thanks.
