The title says it all. I am using the latest driver from Realtek. The optical beam will not turn off, and I believe this is the problem. The computer is looking for an optical device where there isn't one. How can I turn this off? I've played with the sound settings with no luck. This worked before I reinstalled Windows, I don't want to play games (And listen to music, haha!) without sound. If you have any experience with this, I would appreciate your help. Thanks.
