From a4b6027fffedb34d07b671b6aebf85fc1fc2caf7 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 27 Feb 2012 15:00:58 +0100 Subject: [PATCH] ALSA: hda - Add a fake mute feature commit 3868137ea41866773e75d9ac4b9988dcc361ff1d upstream. Some codecs don't supply the mute amp-capabilities although the lowest volume gives the mute. It'd be handy if the parser provides the mute mixers in such a case. This patch adds an extension amp-cap bit (which is used only in the driver) to represent the min volume = mute state. Also modified the amp cache code to support the fake mute feature when this bit is set but the real mute bit is unset. In addition, conexant cx5051 parser uses this new feature to implement the missing mute controls.
