Periodic crashes / reboots when playing

[kabbi]

I've updated your code to support bare PCM5102 (without i2c control, just mocked all functions from pcm51xx to do nothing), and I'm using esp32 d1 mini (no psram) module.

Audio is playing fine, but after 3 to 10 seconds it automatically reboots.

I'm using pcm codec, default sample format (48000:16:2)

Anyway, it works fine for ESP32-CAM board with psram! Thank you for this great project!

Hi Dmitry - Good to hear - I am warming up to do a larger refactoring - main motivation will be to end up with a snapclient component that is easy to reuse in other projects. /J
