nullpointer

Hi I'm trying to cancel echo for orange pi pc plus any idea? Methods I've tried and failed so far https://github.com/voice-engine/ec Bu yöntem de doğru hardware bilgilerini bulmadım http://alsa-project.org/db/?f=d75c947d6147c6c00b31ba67bd1a6d62c010cfad

Hello, my orange pi device crashes to white screen at random times. And in this case USB, ethernet does not work.Which logs should I look at?

Thank you, but these were not the solution.
