Audio Issue in Zoom Meeting When Sharing Edited Artwork Video

I host a Zoom meeting, and when I share a YouTube video of my edited sample of wall artwork, my client can hear the vocals but not the music that I used in the video.

I am looking for a solution to this problem. The issue is the same when showing the video while sharing the screen. When I screen shared and enabled audio, my client could only hear the singer's voice and not the music. This is an issue I've never encountered before. Any insights or help would be greatly valued.
