FC4 was great on my 600X. FC5.... not so much. Sound doesn't quite work. When I turn up the volume, it's like turning up a silent signal: the noise volume increases, but still no sound. So I think it has the chipset right, but something's muted, and I don't know how to fix it. Pointers to a "hey dummy, do this" page would be great. Many thanks, Chris Schumann
