SPI and I2C

It seems that most people are not familiar with their boards.

I2C

I2C channel 0 is usually used to communicate with the audio chip. So if you want to use I2C in your project you can't use Wire (on channel 0) and have to use Wire1 instead!

SPI

SPI (using VSPI) is used to communicate with the SD Drive. So one way to deal with this is to deactivate the SD in the AudioKitSettings.h. An other possibility is to use another HSPI: see https://www.esp32.com/viewtopic.php?t=20755
