-* Analog Loopback +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 +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 +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 +Mic Jack Mode, Line Jack Mode, etc These enum controls the direction and the bias of the input jack pins.

-* Smart 5.1 +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 +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.
