I installed a Logitech Brio webcam when I moved from my ATDs to my LG monitors. It connects via a USB-C on the back of the webcam, to a USB-A port.

It works in all my collaboration tools, FaceTime, Zoom, Skype, Teams, etc., and the image and sound is great.

However, I have to connect the Brio via my external CalDigit Elements Hub, otherwise, I get very noticeable interference in the sound.

If I for instance connect the same cable to my Mac Studio, a second into a FaceTime call, the other folks on the call cannot hear me at all, they are just getting a humm. I move the cable to my Elements Hub, and all is fine.

I tried with a USB-C to USB-C cable as well, and the result was the same; when the Brio is connected directly to my Mac Studio, any call will result in a humm on the recipient's side (video is fine), and if I connect via a Hub, be it my monitor or my Elements Hub, all is fine.

What gives?

Check the Audio settings in System Preferences to make sure that the Brio is selected as the audio source.

Does the webcam require any software/drivers from Logitech or is it simply plug-and-play?

It almost sounds like it is picking up some sort of interference from the Mac Studio. Are you using Bluetooth or a keyboard/mouse dongle?

The Brio is set as audio input, and it is really just plug’n’pray.

As for BT, all I am connecting wirelessly is the trackpad and keyboard.

Are you running Logitune? Make sure it's up to date. I occasionally use my Logitech Brio or 4K cam (basically the same camera) and do not have this issue.

Wish Logitech would update Logitune and G-hub to be AS-native.

Yep - all my software is 100% up-to-date (I use MacUpdater).

Do the LG monitors you have also include a USB hub? Does your brio sound fine if connected there? I personally connect my logitech 4k pro magnetic webcam (basically an Logitech brio packaged with a magnet) into my monitor and have no issues.

I have also connected directly into my Mac Studio with no issues.

If it is new maybe you just got a faulty one?

The Brio works fine via the LG hub. Only when I connect it directly to the Mac Studio do I have any issues. It works in all other situations.
