WAV Trigger stopped working

Sensors Sound & Audio
1

My WAV Trigger was working perfectly for two days but it suddenly stopped and now I’m getting 3 long LED flashes on startup then a solid LED when I try to trigger a sound (but no sound is played).

It’s not the SD card or my WAV files - I’ve tried several new cards of various sizes (all under 32GB), reformatted them with SD Card Formatter APP, removed the init and tried the single file 001_Number.wav… inspected the SD card reader solder joints… tried new power supplies and voltages…

Any other suggestions? I just ordered two replacements/back-ups but hoping to kickstart this one today.

Thanks

Update: just discovered that the WAV files are in fact playing but are slowed down by about 15 x (had to crank up the volume to realize it) and the solid LED eventually turns off after the screamingly slow WAV finishes playing.

How do I reset this?
