I recently bought a 2005 Dual 2.5 G5 and since buying it have not yet been able to get my sound card to work. I've tried different PCI slots, sent it back to the factory to check compatability and it is. It worked fine in my old G4 under OSX 10,3. I'm using 10.4.5 with 3 gigs of ram and 2 250 gig internal drives. I've installed the driver and the mixer app in login items and still the card doesn't show up in the profiler. Any body else ever run into this? Thanks, Jon
