When streaming video and audio, such factors as software, internet speed, bandwidth stability, and network security can affect the video/audio quality. In this article, we will explain how to troubleshoot potential audio/video issues.
Enabling video and microphone access in the browser
- Google Chrome is highly recommended to share your camera and screen. However, it is also possible to use Firefox, Opera, Safari, or Microsoft Edge. Make sure you are using the latest browser version. See the section below to check your browser version and update it if needed.
- Check your microphone and webcam in your browser settings.
- Check if your camera/microphone permissions are allowed. You can verify that by simply clicking on the lock icon to the left of the address bar.

Google Chrome

- Allowed sites: Sites can start to record when you're on the site. If you're using a different Chrome tab or a different app, a site can't start recording.
