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.





Conexant codecs
