Can't hear Sound from movie

[Santa Pat]

I use OBS Cam for Zoom calls and when I play a short video at the beginning none of the participants can hear it, not even me (host) but the audio is in the OBS recording. What am I missing? I want/need for the participants to hear the audio of the movie.

This is impossible.

A very strange idea and I think it's not possible.
