Yes, except "subwoofer" control is to be connected to subwoofer's own
pin (for instance, 0x17 on Lenovo machines). Subwoofer pins I've seen so
far have their own output amplifier with mute.
Apart of this, adding presets has usual benefits like giving other
controls descriptive names (say, "Int. Mic" instead of just "Mic"), but
obviously it has nothing to do with a subwoofer.
