From ffe4d12b151018e831f0ca2e05fe78a55238c517 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 23 Nov 2012 08:34:13 +0100 Subject: [PATCH] ALSA: hda - Add a fixup for internal mic on MacBook Pro 8,1 The internal mic on MBP81 gives only the right channel, and the left channel is static. Add a verb to fix the ADC2 channel mode to expand mono right to stereo.
