From 967303dabc22335e83c6ee4a9e0684a7c05da976 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 19 Feb 2013 17:12:42 +0100 Subject: ALSA: hda - Add the generic Headphone Mic feature This patch improves the generic parser code to allow to set up the headphone jack as a mic input. User can enable this feature by giving hp_mic hint string. The former shared hp/mic feature for the single built-in mic is still retained. This detection can be disabled now via hp_mic_detect hint string, too.
