From 776e184e8082a4ec9bf4fe18b11dae6dc4e43d1f Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 29 Aug 2007 15:07:11 +0200 Subject: [PATCH] [ALSA] hda-codec - Add Mic Boost control with auto-configuration Some codecs need Mic Boost mixer controls for obtaining a proper recording level, but the auto-configuration doesn't create them. This patch adds the creation of mic-boost controls on corresponding codecs.
