While poking around on YouTube using the Chromium browser all
audio output on my Pi3+ went away without obvious cause. Normally
the audio comes out the HDMI port and is picked off at the headphone
jack on the monitor, with no special setup that I'm aware of.

The levels are not mute on both the browser and the system,
the speaker system picks up hum when I touch the cable end
where it plugs into the monitor. Chromium reports it is at
Version 65.0.3325.181 (Official Build) Built on Raspbian ,
running on Raspbian 9.6 (32-bit)

Are there any other software switches or status that can be checked?
It's possible the monitor's audio section quit, but software trouble
seems a great deal more plausible.

Is there a way to bypass the hdmi in the monitor to check for output
directly at the Pi's audio jack?

I've not yet tried rebooting, but will do that as soon as a running
job completes.

Thanks for reading, and any ideas!
