RaspiAudio+ V2 without the mic, "How To"

Does anyone know of any tutorials, on how to use the Basic RaspiAudio+ V2 on a RPI Zero W? Ever since the HA Team introduced these audio Hats. But, I can’t find any info, on how to use the RaspiAudio+ V2, with Home Assistant.

So, I was able to get music to play, using Volumio thru the RpiA+ v2, on a Rpi 0/w. But, I am unable to control the volume, of the speakers.
