I use an AT2035 mic, and im sure that its plugged in. Its not the usb kind so i the xlr cables. I hope someone can help me with this issue. The mic works when the 3.5mm end of the TRS dual 1/4 y cable is plugged slightly into the laptop by itself(not all the way in but just about), but doesnt work when completely plugged in. I also dont want it to pick up anything playing out loud in the pc as i record so i use a headphone splitter and put my head phones in with the mic.
