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
