More about : audio Best solution saran008 March 8, 2010 11:47:05 AM Give your mobo details first. If you are using In-built sound. It's aready defined, ac97 or HD. you cannot change that. Install the proper drivers first. You can change settings in your settings, so that you can use LINE IN for REAR Speakers & MIC for CENTER/SUBWOOFER.
