Random crackling / sizzling Raspberry Pi 5 and POD UX1 (with video)

Hello guys new here with Volumio I used to have a Moode audio in the corner, but I’m here for the raspberry pi 5 compatibility.

From a fresh install and just turned the spotify connect plugin on, I got some random crackling.

I’m trying to understand why and if there is something that can be tuned.

I saw some weird posts about HDMI ports but as I don’t even know what’s happening here.

Well here’s the video explanation if you have some free time :slight_smile:
