Raspberry Pi Audio Hat support

[hkphantomgtr]

Recently I'm trying few cheap clone audio hats on my Raspberry Pi 5 (4g memory) for some CAS/audiophile beginners.  Initially I thought these hats will be recognised by those OSes for raspberry pi automatically and then they just works together.  The fact is totally not.

I've tried on latest Raspberry OS, Ubuntu, Volumio, and Moode.  They all got no sound from the hats before some configuration steps.  For Volumio and Moode, it's easier, they got a place (GUI) to let the user to choose from a very long list.  For Raspberry OS, and Ubuntu, the user got to add a line in "/boot/firmware/config.txt" to tell the OS which overlay to load for this hat.  Of course, the user got to input a specific and a valid name here.

And the most interesting things is, that specific name of hat works in one OS, but may not works in another OS.  (What?!) I need to guess and try from the seller's "instructions" in different OSes.  Great!  Maybe that's why these clones are cheap.

Whatever, I wonder, maybe in later release, SnakeOil for Raspberry Pi can provide a place in Webui to let user to choose the hat.  (those overlays already come with OS.)
