Audio device fails in meeting

Here's a step-by-step guide to help you get your audio working again:

Check Audio Settings in Zoom:

During the Zoom meeting, click on the "^" arrow next to the microphone and speaker icons on the bottom left corner of the Zoom window.
Ensure that the correct microphone and speaker are selected from the list of available devices.

Test Your Audio:

Click on the "Test Speaker" and "Test Microphone" options to check if they are functioning correctly.
Make sure you can hear the test sound and that the microphone picks up your voice.

Adjust Audio Settings on Your Computer:

Check the volume settings on your computer to ensure the speakers are not muted and the volume is high enough.
Make sure the microphone is not muted, and its input level is appropriately set.

I have the same problem. I just upgraded to version 5.15 (I lagged upgrading for way too long) and suddenly other users on a Zoom call report my audio both becomes garbled and then drops-out after a few seconds. Zoom has become unusable. This happens with both Zoom video and Zoom Phone. I'm running linux and have not replaced or upgraded any of my USB devices recently. This appears to be an issue with the Zoom software, itself. When I use other videoconferencing platforms, everyone can hear me just fine.

Same problem, and I'm desperate! I started a new job nearly two weeks ago and they use Zoom and I've had nothing but trouble with the audio and it's starting to make me look bad. Like @phxsmiley said, I have a Dell laptop with Windows 11 and I have tried multiple headsets, some wired USB and some bluetooth and they all have the same problem. The audio settings test perfectly before a meeting but usually not long into the meeting I suddenly get a message that my microphone is no longer detected. If I don't have to speak in the meeting then sometimes I'll just wait (5 minutes maybe?) and then sometimes the microphone will suddenly be detected again. I can't keep ordering new headsets hoping to find one that will work because, like I said, I've tried multiples already so I don't think it has anything to do with the headset. It's gotta be something to do with Zoom and Dell and maybe Windows 11. I never had any trouble like this on Windows 10 and Microsoft Teams and my Dell laptop in my last job. I have done the steps suggested by @Jameswalter many times--that is not the issue.

@phxsmileyDid you ever find any solution? You posted this about a month ago.

In case this is of any use to anyone. My issue was present using Zoom for openSUSE linux. Hadn't had any issue until upgrading to versions newer than 5.13. What _has_ worked is installing distrobox, installing the debian docker file through distrobox, then installing the debian version of Zoom. I exported the debian Zoom app to my openSUSE system and it now works like a charm. Sorry this fix likely won't help those of you with Windows issues.

I've had the following happen to an instructor in 2 different classrooms recently:

Zoom has the cameras listed under the Start Video button, but when you go to start the cameras, Zoom gives the error message it can't start a camera.  Happened to a faculty member twice Monday and yesterday in 2 different classrooms.  His microphone would also sometimes go from being detected to not being detected, and in one of the rooms Zoom said the mic was malfunctioning.  First time I went in after his class, he logged back into Zoom, and everything came up fine, unlike when class started.  I had him log out of Zoom and then I logged in and I can't start video from that PC.  But I can start video in my office with my webcam.  

This morning I walked into both classrooms, logged into Zoom, and there was no issue with Zoom starting or detecting camera and microphone.

App version is 5.15.11, computers in the classroom were Dell desktops, and my laptop is a Dell also.

I also have problems but with brand-new otherwise Bose headphones connected via Bluetooth to a MacBook Pro running MacOS Monterey 12.1. Zoom audio settings are correct and the sound checks are perfect. After 15-20 minutes the other Zoom participants hear a crackle from my mic, this gradually gets worse and worse until I leave the meeting. I log straight back in again, the sound is then immediately clear, but only for 15-20 minutes. Zoom seems to 'get tired'! This is hugely frustrating. Would it help if I cable them together? From the above comments it sounds as if it won't. My current workaround is to try using the Bose headphone only as Speakers and the Built-in Internal Microphone as the Microphone. But it shouldn't have to be this way. Any help welcome.

Same problem (mine disconnects after a couple of minutes) - have you found a solution? 

I had a similar issue with Windows 11 & the latest Zoom - my headset was recognised but didn't work with Zoom. It worked fine on my desktop.

In the end I unplugged my headset, opened Device Manager and removed all the drivers under 'Sound, video and game controllers'. I rebooted and it's now working fine.

So, remove the drivers, and it will reinstall them from Microsoft (or wherever) as you reboot.

Initially after the reboot, my laptop showed an error somewhere else (but a related other place!) in Device Manager, then presumably as it downloaded and installed the drivers that went away.
