Razerz Baracuda PRO buzzing when connected via USB-C dongle

Hello!

I have a problem with connecting via the USB-C dongle. I’m using it connected to my PC via provided in the box USB to USB-C cable but there is often a buzzing sound in the right head speaker. Is there a way to get rid of it? It’s very annoying because sometimes it’s loud for longer period of time.
I don’t have this problem when im using the Bluetooth connection. I have all drivers up to date. Is there something wrong with my USB-C dongle?
