I report the same problem with (K)ubuntu 8.10 on MacBookPro 5.1. The only difference is that here just the right channel works, while both left and central do not. Moreover the volume mixer has some more oddities, basically channels switched between them. I attach my MacOS Info.plist file for the HDA chip, hope it helps. Thanks! Lo.
