From 8ed99d976812d1e14a254b9ac1fe6255af8270ff Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 17 May 2011 12:05:02 +0200 Subject: ALSA: hda - Add dock-mic detection support to Realtek auto-parser In addition to the normal mic jack, the mic (or line-in) jack on the docking-station is checked also as a candidate for auto-selection.
