Recently I updated my editing room with active studio speakers. I installed two JBL 308P MKii monitors. They sound amazing playing music but make crackling noises in Davinci Resolve.
When scrubbing through the timeline our while rendering, a hard static noise can be heard from the speakers. During rendering this isn’t so much a problem, but when editing, this is really unusable.
If you google the problem, some people suggest a broken graphics card or a worn-out power supply. Other discussions talk about a ground loop that creates these unwanted noises. Assumed that the reason is the latter — because this problem doesn’t occur when using headphones or connecting a screen with built-in speakers, I search for a noise suppressor.
A quick Amazon search presented a ground loop insulator. I bought this one: https://www.amazon.de/gp/product/B019FC6ZQQ. For as little as €9.55, the problem is solved and there is no audible sound quality difference.
I hope this short article saves someone a headache!
