Pinebook Pro - No Audio

On a more practical note, I'd open up the back and see if the speaker cables are loose. And also verify that the sound jack switch is in the sound position, not serial console position.

How do I tell which position is which?  I see what looks to be a little outline on the circuit board, I'll try moving it to that position.

Good point. Whence we find out, it should be documented on the Wiki.

Hopefully there will be some indication on the printed circuit board which way it's supposed to be, for each function.
