From 3453d8650b53d37560115a01d3048bbb69b479c2 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 12 Mar 2015 20:47:15 +0100 Subject: [PATCH] ALSA: hda - Add workaround for MacBook Air 5,2 built-in mic commit 2ddee91abe9cc34ddb6294ee14702b46ae07d460 upstream. MacBook Air 5,2 has the same problem as MacBook Pro 8,1 where the built-in mic records only the right channel. Apply the same workaround as MBP8,1 to spread the mono channel via a Cirrus codec vendor-specific COEF setup.
