I built a PC for my church to live stream services. We use a PTZOptics camera through our network and stream to facebook. I built the computer 3 weeks ago and the first week we went live the audio was dropping in and out. The week after that it worked perfectly fine. This week it did the same thing as week 1 and the audio cut in and out the whole time. I do not believe this is a hardware issue because we have another computer that I also built that when the audio cuts out we have to stream from that for the rest of the service. That computer has pretty much the exact same hardware as the streaming computer. Now I know what you are thinking, why don't we just use the one computer that works for streaming. The reason is that computer has a separate use. I could change the hardware between the 2 cases and it should work but I shouldn't have to do that. This should work without any problem. I am not saying that it is a problem with vMix I am just asking for any suggestions. If you need more info "Computer specs, Camera, etc,." just let me know. I just need to try and fix this before the next service.

Thanks in advance.

So the camera we have is a network based camera. We connect to the camera through an IP so the sound and video is over the network.

Here is a link to the video. If it doesn't let you view it let me know and I will try and get it to you a different way.

The video is long so I included just a few time stamps of our audio problems to make it easier for you.

Thank You For Your Help!

I apologise for such a late response I didn't get a notification about a new response.
Yes that's exactly is how it's done. It's feed into our behringer sound board then into the Optics camera which then feeds into our network.

I'm not sure on the exact switch. I will check tomorrow.

However what I don't understand is we have another computer that we don't want to stream from because it was built for other purposes and when we do stream from that one (because the other one is broke) it works perfectly fine. Could it still be a network problem even though we stream fine on the other computer ?

There are many other people (phones, tablets) on the network when we stream .

What else is connected to your TP-Link switch?

What are your Power Options set to on the computer?

I'll also assume this is a non-NDI PTZOptics camera.

No, I was referring to NewTek's NDI protocol and the PTZOptics cameras that have it

Your switch may be handling too much traffic. I don't believe your current switch can't be configured allocate resources/bandwidth to certain ports.

You might want to consider a connection scheme that has PTZOptics camera to separate switch (gigabit) to the computer. But first do some testing on non-worship service days if you can. Eliminate other devices on the network, and see if the audio becomes trouble free. Then you'll know that the loss of audio problem is related to the amount of devices on the network.
