I had a similar problem on MacBookPro 5.5, but after the upgrade with latest packages from mactel repositories yesterday (Oct. 9th) , now I can see again the type of hardware under the sound preferences interface, but not sound yet by any means. Sound level was risen higher enough (or maximum) in all possible settings for sound, but no sound.
