From 3b25eb690e8c7424eecffe1458c02b87b32aa001 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 25 Jan 2012 09:55:46 +0100 Subject: [PATCH] ALSA: hda - Fix silent output on ASUS A6Rp The refactoring of Realtek codec driver in 3.2 kernel caused a regression for ASUS A6Rp laptop; it doesn't give any output. The reason was that this machine has a secret master mute (or EAPD) control via NID 0x0f VREF. Setting VREF50 on this node makes the sound working again.
