Windows 10: camera/microphone access for teleconferencing

How can I do teleconferencing? I can see & hear the others on their chosen website but they cant hear or see me.

The free apps I looked into seem to deal with a camera that takes pictures, which doesn't interest me. Can you help??

Camera and Microphone Privacy

Hi Moustafa,

This issue occurs due to permission issue, driver issue, license for an app is out of sync with the license installed on the computer or if the app is not updated. To give permission to Camera and Microphone app, you may follow
these steps:

• Go to Settings.
• Select Privacy.
• Look for Camera, make sure that “Let apps use my camera” is turned On. You may choose the apps that can use your camera as well.
• Go back to Privacy and select Microphone, make sure that “Let apps use my microphone” is turned On. You may choose the apps that can use your microphone as well.
  

If the issue persists, we would suggest that you check out this

Facebook messenger won't access camera or microphone

When I try to video chat with someone on Facebook, I get that message.
Code:
An error occurred when tryin to get access to camera and/or microphone. Hardware access error. To make a call on Facebook, you need to turn on your camera and microphone on. It used to work fine. Now I have that error in all my browsers. And it's activated. Have verified privacy settings to allow both of them.

 

Camera and microphone

I tried to use the camera to make a video - on Lenovo Ideapad 330S OS 10 - but the "microphone muted" message prevented the video to record.

I did the settings/privacy/microphone suggestion to no avail. I tried to get Cortana to turn on the mic but she cannot hear me. I did the steps to turn her on but she still can't hear me. Suggestions? thanks
