From 91d8344266a8d8a87120dbf0d8e93901b457a97a Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 26 Jun 2012 17:35:10 +0200 Subject: [PATCH] ALSA: hda - Fix power-map regression for HP dv6 & co The recent fix for power-map controls (commit 6f217da228a) caused regressions on some other HP laptops. They have fixed pins but these pins are exposed as jack-detectable. Thus the driver tries to control the power-map dynamically per jack detection where it never gets on. This patch adds the check of connection and it assumes the no jack detection is available for fixed pins no matter what pin capability says.
