People tell me I'm freezing

[smitpat]

People tell me that I'm freezing when I talk on Zoom meetings. This happens fairly regularly.

Platform:

MacBook Pro, i5 quad-core, 16gb RAM

macOS 11.6.1 Big Sur

Dongle w/Logitech webcam & Blue Yeti microphone

What we've tried, which seemed to make no difference:

Speed test (fine), upgraded bandwidth (twice) to 400mbps/20mbps, remote testing of line (fine)

Updated macOS to 11.6.1 from 11.6.0.

Replaced router from Spectrum provided to Netgear purchased

Performed disk repair (disk utility) (fine)

Deselected hardware acceleration (advanced video settings)

Deselect "touch up my appearance"

Still freezing for others.

What we've done since that last meeting (but haven't yet had a chance to test it out enough to reproduce freezing):

Reset NVRAM (twice)

Hardware diagnostic (fine)

Uninstall and reinstall Zoom

Other than reverting to two paper cups and a string, is there anything else we might be missing? Thanks in advance for any recommendations. I am convinced there must be a reason and that consistently stable Zoom meetings is possible.

Hi @smitpat 

Are you on WiFi?  If you are #1 test would be to try a wired ethernet cable to your router. Speed tests are not as relevant as latency and jitter.

#2 Is your audio freezing at the same time as your video?

#3 What exactly is your "dongle". Is this a USB hub or a dock, powered or not? If you can, try getting at least your webcam direct into your laptop.

#4 Do you notice any problems in receiving video/audio in Zoom?

#5 Which Logitech webcam do you have?
