Thanks Jon! I like the mushroom speaker idea since it includes a built-in amplifier powered through the USB adapter, but the size might be a little large for my smart dog door project.
Otherwise, I am able to control and get volume out of the mini-speaker using the ‘amixer’ cmds so I didn’t see anything that would help in the github link (but maybe I missed something?). That you shared. If I can’t find a soln for the low mini-speaker volume, then I’ll likely try the mushroom speaker link that you provided !!
