MCU: ESP32-WROOM-32 (DEVKIT1)
IDE: Arduino IDE 1.8.9
Libraries :
- ESP8266 Audio Arduino Library- ESP8266_Spiram Arduino Library

Problem:
I have successfully assembled and [run the example sketches, but ares struggling to play custom sounds. I believe that the problem can be resolved simply by identifying a method for exporting .wavs. Attached is a sample .wav I would like to be able to play from memory.
Troubleshooting:
- Opened .wav file in Audacity 2.3.0 and exported as .wav (Microsoft header/encoded signed 16-bit PCM)
- Opened .wav file in HxD 2.3.0.0 and exported the contents of the file with the "Copy As > C" function under "Edit"
- Replaced the contents of the example char array (PlayWAVFromPROGMEM.ino, viola.h) with the generated char array contents, name of array unchanged.
- Compile and Upload is successful
Behavior:
- Serial Output consistently indicates that the file is retrieved from memory.
- No Audio from the speaker or loud bursts of static depending on array export settings.
- Error during silence:
AudioGeneratorWAV::ReadWAVInfo: cannot read WAV, invalid RIFF header, got: D5D5D5D5
AudioGeneratorWAV::begin: failed during ReadWAVInfo
