From 54930531a00af5a1c33361a02e67dd1802110465 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sun, 11 Oct 2009 17:38:29 +0200 Subject: ALSA: hda - Fix mute sound with STAC9227/9228 codecs On FSC laptops, the sound gets muted gradually when the volume is chnaged. This is due to the wrong volume-knob widget setup. The delta bit (bit 7) shouldn't be set for these devices. This patch adds a new quirk to set the value 0x7f to the widget 0x24 instead of 0xff.
