^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) Channel Mode
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) This is an enum control to change the surround-channel setup,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) appears only when the surround channels are available.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) It gives the number of channels to be used, "2ch", "4ch", "6ch",
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) and "8ch". According to the configuration, this also controls the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) jack-retasking of multi-I/O jacks.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) Auto-Mute Mode
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) This is an enum control to change the auto-mute behavior of the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) headphone and line-out jacks. If built-in speakers and headphone
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) and/or line-out jacks are available on a machine, this controls
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) appears.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) When there are only either headphones or line-out jacks, it gives
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) "Disabled" and "Enabled" state. When enabled, the speaker is muted
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) automatically when a jack is plugged.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) When both headphone and line-out jacks are present, it gives
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) "Disabled", "Speaker Only" and "Line-Out+Speaker". When
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) speaker-only is chosen, plugging into a headphone or a line-out jack
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) mutes the speakers, but not line-outs. When line-out+speaker is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) selected, plugging to a headphone jack mutes both speakers and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) line-outs.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) Analog Loopback
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) This control enables/disables the analog-loopback circuit. This
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) appears only when "loopback" is set to true in a codec hint
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) (see HD-Audio.txt). Note that on some codecs the analog-loopback
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42) and the normal PCM playback are exclusive, i.e. when this is on, you
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) won't hear any PCM stream.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 45) Swap Center/LFE
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) Swaps the center and LFE channel order. Normally, the left
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) corresponds to the center and the right to the LFE. When this is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 48) ON, the left to the LFE and the right to the center.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 49)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 50) Headphone as Line Out
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 51) When this control is ON, treat the headphone jacks as line-out
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 52) jacks. That is, the headphone won't auto-mute the other line-outs,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 53) and no HP-amp is set to the pins.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 56) These enum controls the direction and the bias of the input jack
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 57) pins. Depending on the jack type, it can set as "Mic In" and "Line
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 58) In", for determining the input bias, or it can be set to "Line Out"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 59) when the pin is a multi-I/O jack for surround channels.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 66) An enum control to re-task the multi-I/O jacks for surround outputs.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 67) When it's ON, the corresponding input jacks (usually a line-in and a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 68) mic-in) are switched as the surround and the CLFE output jacks.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 69)

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 71) When this enum control is enabled, the headphone output is routed
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 72) from an individual stream (the third PCM such as hw:0,2) instead of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 73) the primary stream. In the case the headphone DAC is shared with a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 74) side or a CLFE-channel DAC, the DAC is switched to the headphone
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 75) automatically.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 76)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 77) Loopback Mixing
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 78) An enum control to determine whether the analog-loopback route is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 79) enabled or not. When it's enabled, the analog-loopback is mixed to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 80) the front-channel. Also, the same route is used for the headphone
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 81) and speaker outputs. As a side-effect, when this mode is set, the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 82) individual volume controls will be no longer available for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 83) headphones and speakers because there is only one DAC connected to a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 84) mixer widget.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 85)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 86) Dynamic Power-Control
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 87) This control determines whether the dynamic power-control per jack
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 88) detection is enabled or not. When enabled, the widgets power state
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 89) (D0/D3) are changed dynamically depending on the jack plugging
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 90) state for saving power consumptions. However, if your system
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 91) doesn't provide a proper jack-detection, this won't work; in such a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 92) case, turn this control OFF.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 95) This control is provided only for VT1708 codec which gives no proper
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 96) unsolicited event per jack plug. When this is on, the driver polls
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 97) the jack detection so that the headphone auto-mute can work, while
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 98) turning this off would reduce the power consumption.
