Share screen with sound: Only some users can hear?

It could be that the students who cannot hear the sound of the video clip playing are not using the latest version of the Zoom application, or that their audio settings are not configured properly. Here are some steps you and your students can try to fix the problem:

1. make sure that each student is using the latest version of Zoom. You can download Zoom from Zoom's official website.
2. Make sure that the audio settings of the participants are configured properly. You can check the Zoom audio settings to make sure that the microphone and speakers are selected correctly and that the volume is set properly. Select the Like system (name of your device) option here. 3.
3. use the Computer Audio option instead of Phone Audio when sharing the audio of a video. This option will appear when you click Share Audio. This should ensure that all participants can hear the audio of the video. 4.
   Make sure that participants have not muted their audio during the meeting. Check this by clicking the microphone icon in the Zoom app.
4. If the problem persists, you can also try sharing the audio of the video through another app such as OBS. This will share the video through the app while playing the audio of the video through the Zoom app.

If these steps don't solve the problem, it could be due to the subscribers' hardware. In this case, it might help to use an external audio source such as a Bluetooth speaker to ensure that everyone can hear the audio of the video.
