Hi, I have a A7N266-VM Asus motherboard with an S/PDIF socket. I would like to be able to play the mp3 on my pc through my denon 3300 avr. The denon has a number of optical sockets, so it just a case of connecting the two via an optical cable? Are there changes I will have to make on my mobo to get sounds output through the S/PDIF - would I do this through the BIOS? Thanks.
