Description:
Hello friends.
I was using version 2.0.0 and had my project up and running, today I updated the lib to ESP32 Arduino 2.0.1 RC1 based on ESP-IDF 4.4 and found that it stopped playing audio.
activated the logo and verified that it appears: beginTransmission(): Unfinished Repeated Start transaction! Expected requestFrom, not beginTransmission! Clearing...
any idea what might be wrong to crash after the update?
