I have an Elgato HD60, and in order to capture chat audio they sell a splitter (Elgato Chat Link - 3.5mm 4-pole male into the controller to a 3.5mm 4-pole female for the headset and 3.5mm 3-pole male into the Elgato). When I have this connected plus the controller's data/charge cable I get a buzzing. This occurs if the controller usb cable is connected to the Apex or to the Xbox. If I connect a micro-usb power cord from a phone to the controller there is no buzzing. If I remove the splitter cable and connect the headest directly to the controller there is no buzzing.
I am thinking the power cable to the Apex hub would resolve the issue, but I was hoping someone else who had experienced this could chime in with their experience or thoughts. I was going to get this cable, that OBsIV suggested in another thread.

People in the party have mentioned my mic is cutting in and out, and this only happens when I am using the Apex. If I switch back to the controller and no Apex, my headset/mic audio is flawless.
I have also updated to the latest firmware.
