From 071c73ad5fce436ee00c9422b7ca0c5d629451fb Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 23 Aug 2006 18:34:06 +0200 Subject: [PATCH] [ALSA] hda-codec - Fix mic capture with generic parser Fixed the mic capture with generic parser of hda-codec driver - Use VREF80 for mic pins if available - Handle multiple inputs correctly on audio-input widget node. Confirmed on a conexant codec chip.
