From 5f380eb1eff2031b5101a64c76b54cca8e1c7079 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 14 Sep 2009 15:36:14 +0200 Subject: ALSA: hda - Fix HP/line-out initialization with IDT/STAC codecs It's possible that hp_detect is set even though no headphone pin is detected. The driver issues, however, an unsol event only to hp_pins[0], which can be invalid. This patch adds the check of the valid pin to send an unsol event at initialization and resume callbacks.
