From 93c17f6342ab6d7c878f1424d9b5c4683f8ba89b Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 17 Jun 2013 10:19:49 +0200 Subject: [PATCH] ALSA: hda - Fix pin configurations for MacBook Air 4,2 MacBook Air 4,2 requires the whole default pin configuration table to be overridden by the driver, as usual, as Apple's machines don't set up properly after boot. Otherwise mic won't work, and other ill effect may happen.
