From 6c8194922739138f046a4d0924519dd43b48e1f3 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 10 Aug 2009 18:47:44 +0200 Subject: [PATCH] ALSA: hda - Add auto-mic support for Realtek codecs Added the support for automatic mic selection via plugging for Realtek codecs (in auto-probing mode). The auto-mic mode is enabled only when one internal mic and one external mic are present.
