Buzzing noise when plugging in mic

[davidq]

Hey guys. I just got a new headset, but I'm experiencing some buzzing noise when I plug in my headset's mic. My setup goes as follows:

 

>Computer

          >USB

                    >TASCAM US-122MKII

                              >Speakers

                              >FUNC HS-260 (headset, audio only)

          >3.5mm (sound card on the MSI Z87-GD65)

                    >Mionix Zibal 60 (keyboard)

                              >FUNC HS-269 (headset, mic only)

 

I find that this is the most convenient setup as to avoid having to continuously plug in wires when I switch between my speakers and headset. Although, I noticed that there is a buzzing noise when I have my mic plugged into this setup. When I unplug my headset's mic line from the keyboard, the problem goes away. But when I have the headset's mic and sound line both plugged into the keyboard (instead of the sound line coming from the audio interface), the problem goes away as well. And with that set up, I'd continuously have to go into the computer sound settings and switch the default device whenever I want to switch between my headset and speakers.

 

I'd like to believe that this setup should just work flawlessly, but it doesn't. Can anyone shine a light on a problem that I may have missed?

@davidq: Buzzing noises when you plug in audio gear with male phone connectors (i.e. TS, TRS, TRRS plugs) are completely normal and nothing to worry about, as long as you're not holding them halfway in between unplugged and plugged in.
