I submitted a patch [1] to address some Macbook Air 6,1 or 6,2 HDA
issues, upon request from adrian@. The patch is untested since I do not
own any of these machines, so please apply it and test whether sound
works properly (headphones, speakers, mic, headset mic, jack
redirection, etc.).

If there are any problems, please attach a copy of dmesg after a verbose
boot and "sysctl dev.hdac.X.pindump=1" where X is the appropriate hdac
number for your sound card.
