MAX98357 Not Working With Touch Sensor

[brooksben11]

The problem

Multiple folks are reporting issues using the MAX98357 audio board when a touch sensor is also configured. Media player works fine for folks as does including the "esp32_touch:" component. However, as soon as an actual touch sensor is specified, the audio becomes choppy and slow/delayed. Multiple touch pins have been tried with no success.

I found a workaround. Lowering measurement_duration to 2ms seems to work for audio (including streaming radio for a few minutes) and still respond reasonably well to touch after resetting the thresholds. (Edit: In the end, I ended up at 0.5ms and it behaves almost all of the time. Touch is a little more erratic though.)

Reproducing requires an enabled touch pin, not just the hub, and doesn't seem to care about sleep_duration. It also doesn't care about actual touches, so it should be possible to reproduce without opening existing devices.

@disconn3ct Just tried adding the touch sensor back to my project using a measurement_duration of 0.5ms. Still unusable for me playing a local mp3 file, although it is LESS choppy and slowed down than using the default. Bumping it back to the 2ms you originally mentioned definitely makes it worse. Not sure why radio streaming is working for you.

I also noticed this in my logs (don't think I looked before), but when the touch sensor is included I get this repeating continuously:

Whereas it's just fine when the touch sensor is NOT included.

It stopped working overall and I had to disable the touch sensor.
