I'm new to Teensy (after Arduinos), so have rather a lot of learning to do.
After playing at flashing the on-board LED and testing the hardware setup, I have uploaded the WavFilePlayer sketch from Examples/Audio/Tutorial, and have the Teensy 3.2 + audio shield connected to the USB of my laptop. No other attachments. Initially it starts to play SDTEST1.WAV quite nicely with a decent sound (in ear buds), but that soon breaks up into a very loud repetitive racket like a jackhammer. SDTEST2.WAV makes that racket right from the start.
The SD card is 8GB, newly formatted (not quick format).
What have I done wrong, please?
