Attached is a video of me showing what is happening. I have a camera going into SDI1 of our computer. When you hear the audio from the video you can hear how it is constantly chopping in and out. When I got to the general audio settings of SDI1 you can see that the audio levels of PRE are consistent but once they get to POST they are visibly cutting in and out. I verified that this is a vMix specific thing, when I record the audio of the camera somewhere else the audio is completely fine. This happens to all cameras (max of 4) that I connect via SDI so it is not a hardware issue. For the vMix audio settings, Master Sample Rate is 48000, Master Bit Rate Rate: 16 Bit PCM, recording audio: vMix audio, format: 48000 Hz 16 bit 2 Channels.

Any ideas or help would be greatly appreciated.

Thank you
