ESP32-A1S Audio Out Troubles

[Z34N1X]

Hey Everyone!

I'm having a bit of trouble getting audio out of my ESP32-A1S and could use your help. With ESP NOW, I'm able to send a signal from a D1 Mini to the A1S, but I cannot get the signal to activate either a wav file on the SD card or a header file with wav turned into hex. When I use Faust code, it works, which means there's no problem with the board, but there must be something I'm missing or need to implement to get the triggering to output sound through the headphone jack. Does anyone have experience with the A1S or might know a solution to this conundrum?

I'm using the Arduino IDE along with AC101. You can probably tell with some of the code that I'm trying multiple avenues of possible functionality, so sorry for it being a bit of a mess.
