J2 - Selection between lineout or loop back into the power amplifier.

Selection between audio lineout or loop back into the power amplifier. (Footprint only, JP2 next to J2

is connected by default for on board amplifier and on board mini speaker). If J2 is soldered and used

for audio output selection, JP2 needs to be removed.
