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:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=23d30f28275ddd7fdb87f265e9a440baf4a4cf09

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!
