PWM not outputting desired waveforms

[Lennox]

Hi all,

I'm currently working on a wavetable synthesizer project at university. I borrowed source code from a project that Gary DeReese developed (https://github.com/gdereese/arduino-wavetable-synth).

I've uploaded the code to my teensy 3.6 and I can't seem to get the desired output. Right now, the code is set for a sine wave, and I'm getting this as my output:


I'm also getting this warning:


Here's my code:

And here are the libraries I used:

One million won't fit into a 16-bit unsigned integer.

Copying the text of the message and pasting it in your message is a lot easier than an image.
