Audio issue, participants cannot hear my voice in Zoom meeting

Hello @ccheng,

I just answered a similar question for another user.  Please see below:

While in the meeting, please click the up arrow next to your Mute/UnMute icon in the bottom left corner of your Zoom client.  This will allow you to verify which mic is active.  It sounds like Zoom may not be set to the mic you want to use and may be using the built-in computer mic instead.  Select the proper mic from the list and see if this resolves your problem.

If this resolves your issues, please click the Accept as Solution button on this thread so that others can benefit from this as well.

Thanks!

I am not a new Zoom user. My being unable o be heard on a Zoom meeting last night and one today just started on both my cell phone and computer. Is there some download I missed to my Zoom software on both my computer and Apple phone that would cause people to no hear me in Zoom meetings but I could hear them???

Would also like to know how to fix this. I often have just one or two participants that cannot hear me clearly. They can hear but the volume is low for them. I am always the host in these cases. It's odd that it doesn't occur with all of the meeting participants. 

Test audio settings before a meeting
In the top-right corner, click your profile picture, then click Settings. Click the Audio tab. In the Speaker section, click Test Speaker to play a test tone. If you cannot hear it, select a different speaker from the drop-down menu or adjust the Volume.

Regards,

Diana

Still facing this issue myself. Just started a few weeks ago, but I haven't done anything different since before it worked to now. Tried everything that's been suggested, and nada.

I tried to connect with zoom, out in my host id and my meeting number, they said they couldn't find me as a zoom member.  I am having issues with the sound.  I can hear them, they are gearing me very low.

By the way, I entered my host for and conference number into the automated system.  They could not find me. I have been on hold for an hour this evening, waiting for tech support  is anyone out there??????

Just a silly question, but are you working with an Apple product?  I'm thinking that it might be a glitch with Apple computers.  I used my HP last night for a zoom call, no problems.

This is an issue for me and has been for a while. I can hear them, but they cannot hear me. Here's what I've tried.

1. I have uninstalled and reinstalled the Mac client
2. I have switched between my display and computer mic. Neither works
3. I have (successfully) tested all mics using zoom's test tool.
4. I have (successfully) joined a Zoom Test Meeting.
5. I have asked a friend to test their system by joining the Zoom Test Meeting to ensure everything works fine on their end, then setup a meeting with them.... and nothing! I can hear and see them. They can see, but NOT HEAR me!

No idea what to try next! Please help!
