From e29d377814b83af816fb8c1857605b9c4196477b Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 14 Nov 2011 17:13:23 +0100 Subject: [PATCH] ALSA: hda/realtek - Create mono volume controls for mono-outputs When the pin or the DAC doesn't support the stereo, create a mono control instead of creating a stereo control blindly.
