This case is to come up with a method to control the volume from the DAKboard. We need a method to control this from the Settings page and possibly from the screen.

Desired effects:

Be able to adjust the volume from the CPU for Screens and Speakers that don't have volume controls
Be able to adjust the volume on the Screen with a slider for touchscreen and mouse interactions

Things to look into for these controls

Look into alsamixer which is included in the image already
See about chromium extensions that will work in Kiosk mode

a terminal command in the following format will successfully change the volume of the main HDMI-1 on Pi4B in testing: sudo amixer cset numid=1 70%

Next Steps: Determine if the % values are to scale, and test on Orange Pi 3 LTS supported device.
