ECN Forum Forums Technical Discussion Electrical Theory and Applications Switching adapter for laptop interfering with mic

Hello ECN!!!

I am trying to fix an issue with my computer/headset. I just got an analog headset for Christmas and whenever I use the mic people say I have a buzzing noise along with my voice.(And when i test it with loopback i hear it too). However, whenever i disconnect my AC adapter, the buzzing stops and i sound clear.
I believe this has something to do with the conversion from AC to DC in my adapter? Am I correct?
If I am, is there something i can do to stop the buzzing noise? or is there other power adapters out there that doesn't do this?

Thanks!!!
