From: Takashi Iwai Date: Thu, 12 Mar 2015 19:47:15 +0000 (+0100) Subject: ALSA: hda - Add workaround for MacBook Air 5,2 built-in mic X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ccd2ddc1d6c3ebccff5e93aca4076cbcc4105266;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git 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.
