Freeplay Zero with RetroPie 4.7.1 sound issue

[damiante]

Hey Retrobruno, I'm having a similar issue right now. I'm almost certain that it's a software problem as I get the buzzing out of both the speaker that came with my Freeplay shell kit and also my headphones if I connect them via the audio jack. Would you mind writing out the steps you followed to fix the issue? Hopefully it will work for me as well
