Audio Subsystem

[easytarget]

The MQ Pro has good audio capabilities.

• There are three pads on the reverse of he board that can be connected to a headphone jack.
• There are PCM outputs that can be mapped onto GPIO

Try enabling them in the device tree (merge DT config for Nezha and other D1 boards since these have on-board audio already)

Needs suitable hardware (pcm for the GPIO pins, soldering and connectors for the pads)
