`E (1000) AUDIO_HAL: codec init failed!` on ESP32-LyraT-Mini

[j1mmy3]

EDIT: Ultimately, what caused all of the confusion was simply me picking the wrong board via the `idf.py menuconfig`. After this everything compiled and I was able to run the example program. So, I guess the lesson learned was check the obvious things first.

I have a ESP32-LyraT-Mini audio board (it's actually my first ESP32 board)...but looking back maybe not the best choice as first board? but that's what I have....

I have reached Step #9 on the web page: https://docs.espressif.com/projects/esp ... the-device (the "play_mp3_control" example) and when issuing command `idf.py -p /dev/ttyUSB0 flash monitor` I get a lot of output but the concerning one is the following, this is just a snippet of it:

The make matters more difficult I am pretty new to microcontrollers in general with just some initial knowledge of Arduino and most of my knowledge is just software, hardware I struggle with....regardless, what are some things I could initially look for in solving this? What about the settings in the `idf.py menuconfig`? All I did was select:
`AudioHAL > ....ESP32-LyraT-Mini` as the board and saved. Anything else in that menu that I should look at? Other than that, what are some other things I could look for?
