    Red face 22.04.4 LTS audio and video constantly freezing/cutting out during meetings

    Hi! I just set up my work laptop -- a Lenovo ThinkPad T14 -- and I installed Ubuntu 22 LTS on it. I would have used the latest LTS, but the antivirus software that I'm mandated to install only supports 22 LTS. Everything works except audio/video during meetings. My audio constantly cuts out and my video constantly freezes. It's so bad that I have to dial in to the google meetings because my team hears my audio constantly cutting out. I checked my internet connection, first by monitoring wifi and pinging meet.google.com (low latency and no spikes during meetings), then by disabling wifi entirely and using a Cat-6 RJ45 cable directly to my router. Even hard-wired into the router, I still get freezing constantly in meetings. Interestingly however I can play YouTube videos with no video or audio freezes at all both on wifi and hard-wired to the router. I also ran top during the meetings and nothing seemed wildly off or out of the ordinary. I checked CPU temps also, they're hovering around 35 degrees C which isn't out of range for this laptop. Syslog/journalctl doesn't show me anything that might indicate what the problem is.

    I'm using i3 as my window manager but that shouldn't matter. Here's some info on my graphics and sound hardware:

    That last USB device is a standalone microphone that I got to try to circumvent the audio issue, but it doesn't matter which microphone I use (built-in or standalone), the audio issues persist. I'm willing to troubleshoot this, but if I can't fix it soon I'm going to have to ship this laptop back to the company I work for and ask for a Mac instead...

    Thanks in advance!

    Which browser are you using? Have you tried another one?

    Yes, I tried both Firefox and Chrome thinking it was perhaps a browser-based issue. Thanks for responding!
