I have a nice $600 sound system that's collecting dust... It's brand new, and I got it for my ps3 - but now that my ps3 has been shelfed, my poor sound system isn't being used.

It has Optic support, and HDMI. I'd prefer to use Optic - but I need a new sound card. Hunting for suggestions. I have no idea what I'm doing when it comes to sound cards.

It's for a dell Insperon. I'm pretty new at finding new hardware, lmk if you need to know anything else.
