my motherboard is an asus hero vii and can you recommend a av receiver for meWhat computer/motherboard do you have. You may not need a sound card as some on board sound has digital outputs and descrete line level outputs for each channel. If you use a digital output you will need an avr for the decoding, if yours has line level you could just get an amp and let the computer decode. Right now I am using an onboard optical output to my avr
