Audio wouldn't work despite devices working
I recently tried to have a meeting and when I joined, the host couldn't hear me and I couldn't hear him. I tried every fix I could come up with in the short time before we gave up. I tested the audio devices in the app and they worked. I checked permissions and whether my audio was turned up. I looked to see if either of us were muted in the app and there was no indication of that. I restarted my computer. I re-installed zoom. I used the browser instead of the app. I used a different computer. I used my phone. I used multiple audio devices on each of the computer/phones I used. And I've used each of those devices for a hundred or more zoom meetings before this so I know my computer can handle it. And the host has regularly used zoom to record meetings as well and said he'd never encountered this problem.
What else was there I could do?
