Subject: ALSA: hda - Add support for the new 27 inch IMacs
From: Rafael Avila de Espindola <[email protected]>
commit 1a5ba2e9fc7999b8de2a71c7e7b9f58d752c05e4 upstream.
With the attached patch I am able to use the sound on a new IMac 27.
What works:
*) Internal speakers
*) Internal microphone
*) Headphone
I don't have an external mic or a SPDIF device to test the rest.
