Crackling / buzzing

[Azbest]

Hi!

I experience very unpleasent sounds (crackling/buzing type) - they tend to occur especially during slower and 'clearer' music (piano, soft rock) every 10-30 seconds. The device is Moto G3 and the Spotify tends to be the only app causing the problem. Earbuds are fine as well. I tried re-installing the app, also with clearing cache - didn't work. Any thougths?
