Hi,

We received a bug report https://bugzilla.redhat.com/show_bug.cgi?id=1316119
that the headphone jack on a MacPro6,1 stopped working on an upgrade from 4.3
to 4.4.

The bugzilla has the alsainfo, diffing shows that the Amp-Out vals are
different. I tried a revert of 9f660a1c4 (" ALSA: hda/realtek - Fix silent
headphone output on MacPro 4,1 (v2)") but that didn't help.

Any ideas before asking for a bisect? Does this hardware version need to have
the vref fixup as well?

Thanks,
Laura
