Audio works on test speaker and microphone but participants can't hear me nor can I hear them

Hi @jmansur! What device are you using? 

Today I was in a meeting, all was working fine, suddenly I could not hear the others and could not tell if they could hear me.  JBL Charge 3 for speaker and microphone.  Tried changing to my computer's inherent sound devices, no change.  Audio tests normal.  Disconnected and reconnected and still no sound.  Can't find a reason for this behavior.

Sorry, forgot to say on Windows 10

I'm having the same problem on Mac OS 12.3. Trying to use the Zoom chatbot is making me want to scream: I can't find my host key, and the bot keeps sending the code I need to get into my profile to an obsolete email address. I have an important meeting tonight, and no way to fix the problem. Thinking of switching to another online meeting service.

I have been having the exact same problem on my MacBook with Monterey (12.3.1).  When setting up my audio, I can hear the test tone through my speakers and I can hear the test playback of what I say in the microphone. But once I join, I cannot hear anyone else. Nor can they hear me. If I rerun the test setup, it will still show my mic/speakers are working, but then when I resume the meeting again. Others still cannot hear me.

Mac OS12 Monterey - Same problem. We can connect and see each other and can use the chat function, but no audio even though we each ran the test and it showed everything is okay.  ZOOM - what is your reply??

I found a solution to this that was really a user error, possibly related to a change in Zoom (or just me being daft).

These Steps for Each Call Fixed My Problem:

1. Click the "Join Audio" button (not the little 'up arrow')
2. Select "Join with Computer Audio" (not test settings)
3. I hear them and they hear me

Why did I (and possibly others) repeatedly miss these obvious steps? If you do not setup Zoom to join audio automatically, the button in the lower left corner of Zoom will ask you to "Join Audio" with a little up arrow. When I click the "little up arrow" it brings up setting choices, I would sometimes change the settings but always test them and then close the window. But I would still not hear/be heard in the Zoom call. If I selected the larger "Join Audio" button, I get a choice of "Join with Computer Audio" or "Test Microphone and Speaker".  Since my audio was not working in the call, I would retest my settings or try different settings. When I close the that window, I expected to join audio, but looking at the button, it is still prompting me to join audio. Thus, choosing "Join Audio" then "Join with Computer Audio" is the only way to get audio working reliably.

I'm having exactly the same problem. It's really frustrating. It never used to be an issue until last week. I have to leave and come back again to get my sound working, even though the test worked fine before hand.

Certainly! When checking your device settings, make sure that your microphone and speaker are properly connected and selected as the default input/output devices. In your meeting settings, ensure that your meeting software is not muted and the correct audio devices are selected. You can also use a Mic Test tool to ensure that your microphone is working properly. It's also a good idea to test your internet connection and use a wired connection if possible. If you've tried all these steps and are still having issues, contact technical support for further assistance.
