I have my single button proffie saber with @NoSloppy button prop mods.
I have tested the play function and I am able to play other tracks but not this one track. when I hit the power button 4 times as suggested all it does is the av switch flashes but then doesn’t play anything.
the location of the file is tracks/filename.wav
the configuration is pointing to the correct location and the serial monitor can play_track tracks/filename.wav
however it still didn’t play. what I also noticed was that when I used the Play command in the serial monitor I couldn’t turn it off it complained that it was not Riff WAV. I had to unplug the usb (safely of course)to reset the power (i don’t plug in the usb with the battery to ensure it doesn’t short).
but I’m clicking on the power 4 x short click and nothing it just beeps.
