Audio looping after Monterey OS update

Hiiii

Hi all. I am having the same issues as above, previously on my Mac mini m1 and now on my Mac mini m2. I use a logitech hd 1080p webcam. Has anyone found a solution to this problem? Any help would be greatly appreciated. 

Problem disappeared after I updated my M1 Studio to Ventura 13.1 so I'm thinking it was an OS issue.

I skipped 13.0 so no idea about that version. I had also tried a 2nd StreamCam that Logitech sent me with no difference in behavior. I also tried a different webcam (Kensington W2050) which did not exhibit the problem but it's possible I just didn't use it long enough because the mic was so inferior that I sent it back quickly.

UPDATE: Never mind. The problem returned on Ventura 13.1. I see 31.2 is out but I'm not holding my breath.

I have had this problem on my Mac Studio for the last 6 months, soon after I bought it. I have a logitech C920 HD Pro camera/microphone/speakers. It has happened on both Monterey and Ventura, though when Ventura 13.1 came out, it seemed to be ok until recently having updated (downgraded?) to 13.2. Since it's quite intermittent, it's hard to know for sure if it really went away with 13.1. However, my experience seems to fit with a combination of all the other reports.

I will try disconnecting the camera next time it happens and report back. My camera is hard wired to a USB A plug, so can't change that easily. I can't believe that if I got an A-C adapter that that would solve the problem in itself, but it would change the port I'm using. Experimentation is slow and unreliable!

After exploring potential issues with the mac, I reached out to Logitech, they confirmed that it could be an issue with the webcam. They replaced my logitech hd 1080p as it was still under warranty. I am happy to say that I loop no more! 

Hope you find a solution 👍

Just want to say I had this problem too, where a presenter was on Mac. I was wearing Bose 700 RB bluetooth headphones & mic. 
Rebooting, deleting the meeting and creating a new one did not help.

We ended up muting the presenter in Zoom and a phone call for voice. 

Next time I'll try something else for the audio. 

I Also hope that vendors stop pointing at each other for a solution, but just get together and find out what the problem is. 

I have the same issue, my setup however is that I have the Logitec Brio connected to a Dell U3223QE hub, and connect my macbook using USB-C, everything works. But i get the audio loops (on the other side for the listeners) now and then.

However why i made an account to post this is that i have a minor addition to report that might help Logitec or Apple engineers to fix this:

The mic audio loop even happens after I am not connected anymore, so plugging in to the monitor for wired internet, audio speakers and the brio (and mouse and keyboard) poisons somehow the audio drivers, so that even when i unplug, and do a video call, or audio call using zoom, discord, telegram, whatsapp (does not seem to matter what software) the mic loop still happens. I have confirmed that if i restart the macbook (16inch m1 max) and do not connect to the monitor with the brio, it does not happen. I need to do this systematically to avoid this happening in public presentations as this is very embarrassing. It is a shame that such an expensive laptop combined with such an expensive webcam still are not able to work well together. It is a myth that macbooks "just work" as all of this runs fine on the windows PC that is connected to the same monitor and external devices. (using DVI cables and the usb-c hub)

We can rule out the Dell monitor being the problem going on above messages. And have to assume it is the MacOS audio system getting unstable due to interaction with the Logitec driver. (both should not be the case, so this is a call to action for both Apple as well as Logitec devs.)

Same thing happens to me ALL the time - maddening!! Complete reboot is the only fix (which doesnt always work)

I have a Logitech StreamCam and MacOS and exactly the same issue, the audio looping happens even when not using any applications.  I checked sound within system preferences and I could see the audio loop.  I contacted Logitech Support via the phone and they confirmed I needed to place a warranty claim with Amazon the retailer for a replacement unit.  They provided me with an email to demostrate Logitech had reviewed my device and were recommending a replacement.

This issue happens when using:
+ A Mac
+ A Logi or Logitech webcam that has a USB-C output that's then converted to USB-A - either with a convertor cable, or by plugging into a monitor or hub

I've diagnosed the issue for Logi and they're not interested in fixing which is why they send you back to Amazon etc. I even offered to help test some new firmware or software for them but no. 

The solution is to:

1) Either plug directly into a USB-C port on the Mac

2) Get a webcam from pretty much any other company - I ended up going for the AnkerWork B600 which has worked perfectly, connected via the USB hub on my monitor still.
