Hi Guys,
I was wondering what the correct wiring is for the Adafruit MP3 library for the Feather M4 Express. The tutorial https://learn.adafruit.com/native-mp3-d ... o/overview mentions the Feather M4 Express but only gives wiring for the teensy. When wired as follows, there is no sound:

How is the I2S configured in this library? I don't see any link to the Zero I2S library, which works with the M4 Express.
Another question about the MP3 Library itself: How was the sine.h MP3 header file created? Was LAME or something like that used?

Re: MP3 Library with M4 Express
The output is not I2S:

On the Feather M4 Express, DAC0 is on A0, DAC1 is on A1:

You need to wire to the DAC outputs:doesn't support I2S
