I use a USB mic on my PC when I am making recordings however it always has a hum which is think is the dreaded ground loop. The machine I use the mic on isn't a laptop so I can't just unplug the power source.

Has anyone has this issue and how did you over come it?

PS if this is in the wrong forum, please feel free to move it.

Thanks!

Last time I had this issue (with a full headset rather than just a mic) I returned it as defective. The replacement brand (Microsoft) didn't have the issue.

What else is the mic connected to? If nothing else then there cant be a ground loop, since that requires an actual loop.

What sort of mic is it? Cousin has a yeti which is usb and seems pretty noisy to be honest.

Its a USB Samson mic thats connected to a desk mounted arm. I've read up a bit more on trusty google and people suggest that using a USB hub can help rather than plugging into the MB directly, so I will give that a go.

I'll also try different USB ports on the machine and see if that makes any difference.

I tried different USB ports with no improvement, I will have to dig out my USB hub and try that. One other thing I will try is setting up a noise gate with my recording software.
