However https://www.google.com/search?q=humming+noise+but+as+soon+as+I+turn+on+a+game+capture+software&ie=utf-8&oe=utf-8 does find priors.
You would also ask the maker of the unknown game capture software about it.
I'm currently using the corsair raptor hs40 headset and using them to game with.
when in TeamSpeak I have no buzzing or humming noise but as soon as I turn on a game capture software there's a constant humming noise coming through the microphone..
I've tried plugging into different USB slots and disabling all other audio devices not in use but that makes no difference.
It's starting to get frustrating as I'm sure its something simple and hopefully someone knows the answer!
Any help is massively appreciated.
