Hi there,
we're trying to get sound working on a MacbookPro 13,3 (A1707).
So far I've been unable to get the sound working. Did use the HDA analyzer and flipped the out-dir, enable and data on all 8 GPIO's, but none of them got the sound working on either the onboard speakers nor the jack output for headphone.
Is there anyone willing to help on this issue? Driver development is a bit beyond my skills. I can provide hands, debug logs, etc. tho' :).
Currently trying with a default Ubuntu 17.10.1 live USB, but a 4.15.3 kernel didn't help either.
Alsa-info has been uploaded to http://www.alsa-project.org/db/?f=33cc432d3b648d1aa6adc997630817046656a086
The system was booted with an external USB-C dock from Dell, otherwise there's no network and no regular (USB-A) ports available (booting from stick) as the WiFi doesn't work and the device has only USB-C ports. The card 0 is from the dock - it's not relevant (and working).
Before alsa-info ran there was also a USB headphone plugged in, that was card 1. Without those devices card 2 = 0 and 3 = 1 at boot. Issues are with what's listed as card 2 currently, the HDA-Intel - HDA Intel PCH.
Any help is greatly appreciated.
Some people already have some trackers for the current state of the devices. Not sure if they are of use, but might help: https://github.com/Dunedan/mbp-2016-linux/ https://gist.github.com/roadrunner2/1289542a748d9a104e7baec6a92f9cd7
