Audio could not be heard by all participants when screed sharing a website video

The participants on my Zoom session were not able to hear the audio that was being played from a website I opened and was sharing during our call. They could see the web site content I was sharing but they could not hear the audio from the website. I (as the call host) could hear the audio very well. Are the audio settings I need to adjust on my laptop or in my Zoom settings?  

Thank you
