Raspberry Pi Audio Hat support

No way to probe AFAIK. All I can do is to list all the overlay files, and allow the user to pick one... Then reboot and hope for the best.

How does Moode do it? From Google AI

Moode, a web-based audio player for Raspberry Pi, automatically detects and configures supported audio HATs (Hardware Attached on Top) through its audio configuration menu, offering a selection of compatible devices.
Here's a more detailed explanation:
Automatic Detection:
Moode is designed to recognize and automatically configure supported audio HATs, simplifying the setup process for users.
Audio Configuration Menu:
You can access the audio configuration menu within Moode's web interface by navigating to the "m" local menu at the top right corner and then selecting "configure" and then "audio".
Device Selection:
The audio configuration menu provides a list of supported audio HATs, allowing you to select the specific device you are using.
Example:
Moode supports a variety of audio interfaces, including those from GPL (Generic Peripheral Layer).
HAT Compatibility:
Moode is compatible with various Raspberry Pi HATs, including the Raspberry Pi Sense HAT, which is compatible with any Raspberry Pi with a 40-pin (2x20) connector.
Example:
To install the Raspberry Pi TV HAT, press the HAT gently down over the Raspberry Pi's GPIO pins, place the spacers, and tighten the screws.

Moode gives u a list to choose from.  It can't detect the details of the hat.
