In the middle of a call I'm getting this error message

zoom can't detect your speaker

It happens when I start speaking, my voice goes through, everything works, except after a few seconds I get muted and this message shows up.

I tried re-installing with no luck. Is there anything else I can try?

  • @John - Macs don't have BIOS, audio or power drivers. Everything like that is already in the OS. @ Bruno - I'd suspect System Prefs > Security & Privacy > Privacy > Microphone… except I'm not sure how that would affect the speakers, only the mic itself. – Tetsujin Nov 6 '19 at 8:16

Same issue - got this from Zoom support:

Usually this type of issue happens after upgrading to Mac OS 10.15 Catalina. Catalina introduced several new settings and OS features that can cause issues for programs after upgrading. For this situation the best thing to do will be to follow these steps: Uninstall Zoom (How to uninstall Zoom on a Mac?), Restart your computer, and then visit zoom.us/download and install the "Download for IT admins" version. Installing this particular version is important so it can register your device drivers.


this problem you will get because of you did not allow access to your microphone and speaker too, So you will have to give access to microphone for your current device. Just follow some steps for windows 10. 1) go to the bottom right corner and right click on the speaker icon and choose "Open sound setting". 2) then go to "Microphone privacy setting". 3) after going to that particular setting then on the top you will see "Allow access to the microphone on this device", click on "change". 4) "turn on" microphone access to this device. 5) Restart your system.

thats it Enjoy...Thank you.

I had serious issues with Zoom trying to detect my speaker when it was working perfectly fine before! I solved the issue by doing the following:

  1. Right click on the right hand bottom of your screen on your desktop where there is the sound icon
  2. Click on 'troubleshoot sound problems'
  3. Then follow the instructions, where it tests it all out for you! Mine said it was a compatibility issue due to my recent windows update, and it was then fixed!
