From 3db6ff5f188bc0277d26ee2e91e7354efe97560c Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 24 Jul 2009 16:51:47 +0200 Subject: [PATCH] ALSA: hda - Fix mute control with some ALC262 models commit 8de56b7deb2534a586839eda52843c1dae680dc5 upstream. The master mute switch is wrongly implemented as checking the pointer instead of its value, thus it can be never muted. This patch fixes the issue.
