commit 3b25eb690e8c7424eecffe1458c02b87b32aa001 upstream.
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.
