Audio Latency

[F4C]

Hello,

I need technical support for our system!

We recently moved to a new location. The studio is set up again as it was before, and we also have a 1-gigabit internet connection again.

Unfortunately, we had a problem during our conference last Wednesday where the audio had about a one-second latency. So when something was said, you could see the mouth movements, and the words came a second later.

The problem is that I, as the host, could not see the issue. Everything was synchronized for me. But our call participants had the problem. However, it was only with us. Their video and audio were synchronized with each other. It was just our signal that arrived delayed.

We use Sennheiser wireless systems whose audio is sent through a mixing console to an Atem video switcher. From there, the audio and video are sent together to the Mac Mini, through which we host the Zoom meeting.

Nothing has changed in the cabling! Nothing has changed in the Zoom settings! Nothing has changed in the internet quality! I have already tried restarting! I have already tried turning "Sound for Musicians" on and off! I have already tried changing the audio settings! Unfortunately, everything was without success...

I hope you can help me finding the reason for those problems.

Best regards

As an audio engineer I know that audio can get to be very complex and without actually seeing the system I can only venture a guess. I suspect that the delay is in the Atem switcher. Take a look at the following video to see if it helps https://www.youtube.com/watch?v=KZJz2x_Ta9o
