-This file explains the codec-specific mixer controls.
-
-Realtek codecs
---------------
-
-* Channel Mode
-  This is an enum control to change the surround-channel setup,
-  appears only when the surround channels are available.
-  It gives the number of channels to be used, "2ch", "4ch", "6ch",
-  and "8ch".  According to the configuration, this also controls the
-  jack-retasking of multi-I/O jacks.
-
-* Auto-Mute Mode
-  This is an enum control to change the auto-mute behavior of the
-  headphone and line-out jacks.  If built-in speakers and headphone
-  and/or line-out jacks are available on a machine, this controls
-  appears.
-  When there are only either headphones or line-out jacks, it gives
-  "Disabled" and "Enabled" state.  When enabled, the speaker is muted
-  automatically when a jack is plugged.
-
-  When both headphone and line-out jacks are present, it gives
-  "Disabled", "Speaker Only" and "Line-Out+Speaker".  When
-  speaker-only is chosen, plugging into a headphone or a line-out jack
-  mutes the speakers, but not line-outs.  When line-out+speaker is
-  selected, plugging to a headphone jack mutes both speakers and
-  line-outs.

--------------------
-
-* Analog Loopback
-  This control enables/disables the analog-loopback circuit.  This
-  appears only when "loopback" is set to true in a codec hint
-  (see HD-Audio.txt).  Note that on some codecs the analog-loopback
-  and the normal PCM playback are exclusive, i.e. when this is on, you
-  won't hear any PCM stream.
-
-* Swap Center/LFE
-  Swaps the center and LFE channel order.  Normally, the left
-  corresponds to the center and the right to the LFE.  When this is
-  ON, the left to the LFE and the right to the center.
-
-* Headphone as Line Out
-  When this control is ON, treat the headphone jacks as line-out
-  jacks.  That is, the headphone won't auto-mute the other line-outs,
-  and no HP-amp is set to the pins.
-
-* Mic Jack Mode, Line Jack Mode, etc
-  These enum controls the direction and the bias of the input jack
-  pins.  Depending on the jack type, it can set as "Mic In" and "Line 
-  In", for determining the input bias, or it can be set to "Line Out"
-  when the pin is a multi-I/O jack for surround channels.

-
-* Smart 5.1
-  An enum control to re-task the multi-I/O jacks for surround outputs.
-  When it's ON, the corresponding input jacks (usually a line-in and a
-  mic-in) are switched as the surround and the CLFE output jacks.
-
-* Independent HP
-  When this enum control is enabled, the headphone output is routed
-  from an individual stream (the third PCM such as hw:0,2) instead of
-  the primary stream.  In the case the headphone DAC is shared with a
-  side or a CLFE-channel DAC, the DAC is switched to the headphone
-  automatically.
-
-* Loopback Mixing
-  An enum control to determine whether the analog-loopback route is
-  enabled or not.  When it's enabled, the analog-loopback is mixed to
-  the front-channel.  Also, the same route is used for the headphone
-  and speaker outputs.  As a side-effect, when this mode is set, the
-  individual volume controls will be no longer available for
-  headphones and speakers because there is only one DAC connected to a
-  mixer widget.
-
-* Dynamic Power-Control
-  This control determines whether the dynamic power-control per jack
-  detection is enabled or not.  When enabled, the widgets power state
-  (D0/D3) are changed dynamically depending on the jack plugging
-  state for saving power consumptions.  However, if your system
-  doesn't provide a proper jack-detection, this won't work; in such a
-  case, turn this control OFF.
-
-* Jack Detect
-  This control is provided only for VT1708 codec which gives no proper
-  unsolicited event per jack plug.  When this is on, the driver polls
-  the jack detection so that the headphone auto-mute can work, while 
-  turning this off would reduce the power consumption.
