When plugging my head set into the 1/4 in jack at the side of my Blackwidow Elite, i get this really high pitched whining on my streams or when recording. I've narrowed it down to it being the RGB on the keyboard, the tone and volume of the noise varies depending on the cycle/colour/transition and reduces when in line with when the brightness is reduced. I get no noise whatsoever when the RGB brightness is 0 (turned off). This does not happen when i plug my headset directly into my PC, only when using the jack as the side of the keyboard. I have used 2 VST plugins within OBS Studio which has reduced it to a degree (see tutorial i followed here:
RGB on - Can't use headset jack.
RGB off - Can' use headset jack.
Why can't i use both!
