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. Valentine
