I have a computer and the on board sound died. So I put a sound card in it. All works ok but now Media Player won’t play cds. So I installed Real player. Same thing. They will play everything else just not .cda files. Thinking this must mean it is a hardware/device issue. I changed the card, but no good. I researched the errors but they did not help. I have done all the basics you can think of so I am wondering if anyone out there has a usefull answer who has solved this problem?
