There's some sort of binary information. Actually, I played with things a little more, and dug a little deeper into what the ubuntu forums say, and it turned out that I made a stupid mistake, I typoed mbp3 as mpb3 when testing it. Now, I actually get sound with model=mbp3, but the controls are all wrong, e.g. line-out controls the built-in speakers, and the speaker on/off control doesn't do anything to the speakers. Also, I need to turn up the volumes pretty much to max to get any output at all, which seems a little strange. I'll try to figure out what the controls really are and see if I can make a new model that links it all up correctly. Anyway, sorry for the bother and thanks for all the help. In other news, I've got a new aoa patch that actually works on the older models, but so far doesn't fix the quiet sound problem either, I'm still working with Andreas on that. And I'm also working with somebody else to get optical output on topaz-based machines. johannes
