Lost Audio

[Metz49]

Teachers use Chromecast to broadcast.  Recently teachers using YouTube have lost sound.  The teacher is showing a YouTube video and pauses the video to comment.  When the teacher restarts the video there is no sound.  After disconnecting from Chromecast and then reconnecting the sound will play.  There is no pattern to this problem and it happens in every classroom.  Any suggestions?

Is the video played directly from YouTube, or is it embedded anywhere?

Do you have any Chrome extensions that may be relevant for YouTube?

What hardware and OS is the teacher using?

How are the two devices connected to the network?

What type of Chromecast is it?
