Hey fellas,I was wondering if you could help me out,I've got a sony HTSL500 surround sound system and was wondering if it's possible to hook it up to a pc?Ive got a trust soundcard with optical input/output and all the relevent wires and stuff but cant seem to get any sound coming through,I suspect the sony surround sound aint compatible with a pc but thought I'd double check before I give up.Thanks.Dans
