Whenever I try to play cd audio in Windows Media player, I get a message saying Windows Media player cannot read your Cd-rom Digitally it will switch to analog mode.I have two seperate computers doing the same thing.On one computer I have an Acer 50x and another an Aopen 50x. I am using the a Fic AZ11 Motherboard on both. On one I am using intergrated audio on the board ,The other one I am using Aureal Vortex sound card.WHAT IS THE DEAL?
