These messages are harmless. It's just information from the driver,
enabled only when you build it with CONFIG_SND_DEBUG_VERBOSE=y.

Well, ALC882, ALC885 and ALC889A are almost compatible. In the
driver, they are all handled in the same routine.
There are a few models for intel macs with ALC88x. Try to specify
either model=macpro, model=mbp3 or model=imac24 as the module option
of snd-hda-intel driver.
