Mac mini (M1) buzzing audio

Hi,

Just got my Mac mini with the new M1 chip and installed it on my desk.

I am using 1 HDMI cable to a monitor and 1 USB C to DP cable to my second monitor.

All seems to work great combined with my MX Keys and MX Master 3 except for my audio.

I use a Astro A50 headset which has a dock to transmit audio from to my headset. It is attached to my windows workstation using optical but the dock allows multiple inputs. Before I had my phone attached for music using the 3.5mm jack but now I attached this to my Mac mini. On phone it doesn't but on the Mac mini it has a vey annoying pitched buzzing sound.

Hope anyone can help me solve this. (Yes I already tried 3 different cables and even bought a new 3rd one for 30 euros without luck)

I connected it straight to my Mac mini and now its flawless. Seems like the ground is not grounded to both devices. I will get a KVM switch and switch that way so I don't have to keep switching the wires but the problem has been solved for now.
