From 02856b5684677b74095069c3be4774c2992e4fdc Mon Sep 17 00:00:00 2001 From: Jaya Kumar Date: Fri, 23 Jun 2006 15:18:41 +0200 Subject: [ALSA] AD1888 mixer controls for DC mode This patch adds two mixer controls. The V_REFOUT enable is a documented register that couples the microphone input lines to the V_REFOUT DC source. The High Pass Filter enable in the AC97_AD_TEST2 (0x5c) is an undocumented register provided by Miller Puckette via Analog Devices that enables the AD codec to apply a high pass filter to the input.
