hi,
the LyraT use an ES8311 -- Annex has implemented the ES8388 I don't know the differences, you have to try it out if you know the pin assignment - you can try to play an MP3 then you don't need a big code to test

If you just want to hear the LyraT playing, and don't mind installing a Lyrion Music Server https://de.wikipedia.org/wiki/Lyrion_Music_Server,
then the ESP32 squeezelite firmware is an option. https://github.com/sle118/squeezelite-esp32


There are several versions of the A1s, which all have different codecs and pin assignments, but the firmware comes with a web interface, where you can try them all, until you find the right configuration.

A web installer is here: https://sle118.github.io/squeezelite-esp32-installer/

BTW: I totally forgot to mention, that the ESP32 squeezelite firmware also supports Bluetooth.
So you don't necessarily need a LMS server. Just install the firmware, configure it via the web interface, and start streaming music to it via Bluetooth.

I have two of them, and use them as LMS clients and bluetooth receivers.
