When I join a Zoom meeting, I can hear them but nobody can hear me

Nice to meet you, *****!
OK, in the top-right corner there should be your profile icon, please click on it, then open Settings

Have you opened Settings in it?

You need to click your profile picture in Zoom, then click Settings.

Please click on your photo near the search bar of the Zoom application.

Do you see the profile icon near the search bar?

Unfortunately, we are not providing the service over remote connections.

There is another option here. Please start the Zoom meeting. Then, hover over the Zoom window and select the caret  next to the mic icon in the bottom-left corner.
Make sure that the correct microphone is selected — if not, select the desired mic.
If everything seems to be in order, you should test that your mic is working:

1. After clicking the caret next to the mic icon, select Test speaker and microphone.
2. Follow the prompts to get your mic set up properly again.

You are welcome, *****.
