Hello everyone, I have an asus p5k mobo with an onboard realtek soundcard. I decided I wanted to replace it with a more powerful sound card and stereo system, so i got both. I purchased a http/www.newegg.com/Product/Product.aspx?Item=N82E16836121014 and a http/www.newegg.com/Product/Product.aspx?Item=N82E16829271001, but only one speaker plays! Please help!
