Maybe it’s just me being dumb, but I’ve yet to find a way to get 5.1 sound out of the iMac. I expected to find lots of USB or even FireWire sound cards out there but none seemed to support the Mac.
Enter the Firewave from Griffin. A shame it is not yet available.
This is exactly what I wanted: a way to use my current 5.1 speaker setup (which I’m wasting on my PC at home since it became only a server) on my iMac G5 for my gaming pleasure.
Kudos to Melo for finding it.
