From b4e818768d50a5b7aa1635676839682bcf0691b6 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 18 Nov 2009 17:20:24 +0100 Subject: [PATCH] ALSA: hda - Fix mute-LED sync on HP laptops with IDT92HD83xxx codecs The mute-LED isn't synchronized with the actual mute state on some HP laptops with IDT 92HD83xxx codecs. A similar hack using check_power_status callback is added for this codec, too.
