Others cannot hear the video I am screen sharing
When I screen shared a video, others can see the video but cannot hear it.
Only I can hear the sound from the video I screen shared.
For YouTube Videos
Instead of screen sharing YouTube videos from another browser tab outside the virtual room, we recommend that you watch them within the virtual room by simply copying, pasting and saving the URL. The video will stream directly from YouTube with full audio.
For non-YouTube Videos
If you are screen sharing a video which is not on YouTube (e.g. a Vimeo video on another website, or saved locally on your computer), you may have forgotten to enable audio-sharing.
Switch off screen share and select the checkbox for Also share screen audio before switching on screen share again.
When selecting which option to screen share, make sure that the checkbox for Share audio at the bottom left corner is also ticked before clicking Share. Due to browser or OS constraints, this checkbox may not appear for some options, which means that these options cannot be used with audio sharing.
Problems with Only One Member Being Unable to Hear
If only one or a few members seem unable to hear audio from your video, it is possible that it is a local issue with their device. You can try testing this by checking if they are able to hear the audio from your video chat.
