I can't provide any insight here, but I did want to point out that I have a Android 8.1.0 device (Galaxy J3) and am getting the same "jitter" effect. So I don't believe it's isolated to versions below 7.

Just didn't want anyone chasing the wrong rabbit, since the readme hints that the issue may be related to older Android versions :P

Yeah so unfortunately, I think it's an issue with PICO-8 itself. Now that I've written WasmBoy, and know the WebAudioAPI better, it has to be something with how they handle audio in emscripten. So there's nothing I can do about it. You'll notice the same effect if you go on the PICO-8 bbs with your phone.
