From fefd67f31ee7f5259344e36a237d59b47e8715cf Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 30 Jul 2009 18:03:05 +0200 Subject: ALSA: hda - Add line-out jack detection on IDT/STAC codecs Add the automatic mute of speakers via line-out jack plugging on STAC/IDT codecs. The feature is enabled when the HP detect is present.
