-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.

-IDT/Sigmatel codecs
--------------------
-
-* 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.
-
-
-VIA codecs
-----------
-
-* 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.
-

-
-* Auto-Mute Mode
- See Reatek 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" and "6ch".
- According to the configuration, this also controls the
- jack-retasking of multi-I/O jacks.
-

- 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
