But I came across this link about ESP8266 having the same problem. It was solved by using a different USB to serial converter. Although my FTDI serial converter i...

Re: Use ESP32 as FM transmitter?
Great, looks promising. Hadn't looked into the RMT before. Another question from the great noob: I need to play several small wav files simultaneously (8000 Hz, mono, 1 second duration), and originally I was thinking about using a multichannel SPI DAC.
