Add vref to macbook 5,2 external headphone jack
Attached is a kernel patch to the 4.0.5 kernel adding the needed vref bits to the output jack. This resolves the sound issue.

alsa-info output with the headphones after the patch
This is the alsa-info with the patch applied and the headphone plugged in.
Could you check the patch below? If this doesn't work, try to adjust the pinctl value of NID 0x18 and 0x19 manually via hda-verb, e.g. hda-verb /dev/snd/hwC0D0 0x18 SET_PIN_WID 0x21 hda-verb /dev/snd/hwC0D0 0x18 SET_PIN_WID 0x21 Change from 0x20 to 0x27. My test case was to play some sound using aplay and insert headphones listening for sound. I was able to use hda-verb commands to enable set the VREF bits on the 0x15 pin. I tested setting VREF_80, VREF_50, VREF_100. They all seemed to produce sound from the headphone slot. VREF_HIZ and VREF_GRD would result in no sound. I tested that it still worked after a sleep. I reused the alc889_fixup_mbp_vref function in the patch noticing that it happened to set an appropriate bit on the 0x15 pin. I did not attempt to clean up or reduce any of the other potential quirks. Is there something else that I should test or try? Is there any other information that would be useful? Ah, I overlooked your patch. Basically it should work by just replacing ALC889_FIXUP_IMAC91_VREF with ALC889_FIXUP_MBA11_VREF or _MBA21_VREF.

I will apply the patch in comment #6 and test it this evening when I have access again to the machine. I have tested the patch and confirm it fixes with the audio output on the headphones. Thank You. Good to hear, I queued the fix now. It'll be included in the next pull request, hopefully merged in 4.2-rc5, and backported later to stable kernels. |
