<pre>I ran your test case against an iPhone 6S running iOS 9.2, and observed the following behavior:
Playing to the internal speaker.
1. Load page, hit OK.
2. Sample rate is 48kHz, no distortion.
3. Plug in headphones.
4. Distortion observed over headphones.
5. Unplugged headphones (restoring playback to the internal speaker).
6. Distortion disappeared.
However:
Playing over headphones.
1. Load page, hit OK.
2. Sample rate is 44kHz, no distortion.
3. Unplug headphones.
4. Distortion observed over internal speaker.
5. Plug in headphones.
6. Distortion disappeared.
So this appears to validate the theory that the audio hardware sample rate is changing dynamically between 44.1kHz and 48kHz and causing the distortion.</pre>
