I was wondering if it is at all possible to connect my asus to the logitech z906 and utilze the 5.1 surround sound. My g53 does have a sound card in it, but it was the standard sound card for 3D audio. I read on some logitech forums that it could connect and work if one has an external usb sound card. Are there any other ways to connect w/o having to buy the external sound card? Thanks ahead of time to everybody that answers!
