Description Thomas Zwaagstra 2012-06-12 08:54:16 UTC 
intel-hda Realtek ALC889A on macbook pro 5,2

After kernel 3.4.0-rc2, no sound comes through the headphone jack.  Otherwise sound still appears to work with internal speakers.

After a git bisect, this appears to be the breaking commit:

I have tried various "model=" options, but without luck.

Applied patch the patch, and I can confirm that it has solved the issue.  Headphone audio now works as expected.

Thank you Mr Iwai!
