Hi,
I have adapted one of the example sketches of the Teensy internal memory raw player to a sound player of raw files on the memory card of the audio board.
Unfortunately I have no sound - but also no errors..
Can someone give me a hand at debugging?
I converted the mono wave files to raw with audacity (also with sox - but no difference there)
Thanks!
