Sounds on Feather M0 Express

Using MakeBlocks with an Adafruit Feather M0 Express, I have been unable to get Play Tone or Play Sound to work. No matter what I code, even using the simple tutorial examples, all I get is one High-Pitched tone that does not stop. I have tried different boards and different piezos, but the result is always the same. I can write comparable Arduino code for the same components with no problem.

Doe Make Code have a problem, or do I?

I cross posted this on the Adafruit MakeCode Forum, seems like others have similar problems:

Also. I tested it with an Adafruit Metro M0 Express and got the same erroneous result.
