From: "J. Neuschäfer" <j.ne at posteo.net>

Line out playback and microphone capture work, after enabling the
corresponding ALSA controls. Tested with the Orange Pi Zero interface
board, which is a (mostly) passive adapter from the 13-pin header to
standard connectors (2x USB A, 1x Audio/Video output, 1x built-in
microphone).
