Noisy audio

 
Hi. I am quite new to Aximmetry. I would like to use it for live events. So yesterday while testing it with a live camera with audio and sending the output to Vmix on a different pc, i found the audio become very noisy as the Aximmetry pc starts to run faster. My camera input is 2160P 25 resolution. Audio is from an audio board sent to the camera. Camera to Aximmetry Pc is via SDI to a Blackmagic Decklink. Then output to Vmix pc via SDI.
I am using a Professional DE Aximmetry license ( just got it 2 days ago ). My Aximmetry PC is using I9 intel and 3090 gpu cards. Is there a way to optimize this better so that the audio output is not noisy?
