Regarding sleep pin for volume control option

Hi

I am using TX1 can I connect the volume control pin SLEEP to a pot pin input of an audio dac how is the nature of the pin when used as o/p for controlling the volume of a dac typically devices like TLV320DAC3120 can this be done TLV320DAC3120 this requires a potentiometer input for controlling the volume

This pin is used as input to BUTTON_SLIDE_SW on TX1, it is shorted to GND when pressed. I don’t think it can be used as potentiometer input.
