I am trying to get WAV files to play off SPIFFS to i2s. It nearly works, but I keep getting a stack error after either 20 or 21 plays.

Can anyone tell me what might cause this?

thanks

- Sun Jan 17, 2021 10:16 pm #90254 I found this error from my Wemos D1 mini when playing MP3 from i2s Audio. Not sure any fixed info? Thanks

More info... When replace AudioOutputI2S with AudioOutputI2SNoDAC I get the same error.
