From 5d5d5f43f1b835c375de9bd270cce030d16e2871 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 12 Feb 2008 12:11:36 +0100 Subject: [PATCH] [ALSA] hda-codec - Implement auto-mic jack sensing on Samsung laptops Implemented the auto-mic jack sensing for Samsung laptops with AD1986A codec chip (model=laptop-eapd). The hardware uses pin 0x1d and 0x1f for the internal and external mics, respectively.
