From 0b4df931ce3502311928bf66088cd76a2b5e604f Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 10 Jan 2013 09:45:13 +0100 Subject: [PATCH] ALSA: hda - Avoid auto-mute or auto-mic of retasked jacks When a jack is retasked as a different direction (e.g. a mic jack is used as a CLFE output), such a jack shouldn't be counted as the target for the automatic jack switching. Skip the automute or the autoswitch when the current pinctl direction is different from what we suppose.
