I2S to A2DP Source distorted audio

[nadnaks]

I'm trying to read an audio signal(a simple square wave tone from another ESP32) using I2S and send that signal to a Bluetooth speaker using A2DP source. However, the audio is being distorted heavily. The example we are using is base-I2S-A2DP from the audiotools library. Do you have any ideas as to what could be causing the noise?

I have never tried, but others seem to have issues as well: see pschatzmann/arduino-audio-tools#26
