My computer has lost sound, it was working fine a couple of days ago and now it is gone. I checked the audio devices and it says their is no audio or video devices which is not true because I do have an radeon HD2600 pro that has audio and an asus P4P800-E that has onboard audio. Could it be a driver issue? I don't know where the CD's are that came with my mobo and the asus website dosnt have anything for my mobo only the P4P800-E deluxe. Any suggestions?
