Nothing, despite changing settings "headphone" and "IEC958" in alsamixer
-c0 (alsamixer by itself picks up pulseaudio nowadays apparently). It's
as if the amp is powered down, or we route everything to modem :-)
Never a click or a buzz. I also have mic routing to pcm turned up and
this makes no sound. Entering the jack to the headphone socket also
makes no "click" in the headphones as you could maybe expect.
Maybe there is a special GPIO floating about that enables amp power?
