I've had this problem for a while now. I attend regular meetings and my job is to occasionally share short videoes.
Maybe 1 out 4 times there is no sound and someone else has to step in and share the video.
For the meeting today I did a sound check before the meeting and there was no sound when sharing the video. I restarted my computer and didn't have anything open and then sound was fine. 20 minutes later it didn't work. I didn't touch anything else and did used the exact same video and settings.
I run the latest version of zoom on Windows 10.
And yes, I have checked the box for "share sound" and "optimize for video".
Is there anything I can do? I feel like a complete idiot when people message me that I have to check the box to share sound. I have this problem about once a week.
I've seen this before and had a similar experience. It would be best to make sure that the music output is the PC when sharing music. You may have a blue tooth wireless speaker that the music defaults to; thus, stopping the playing of sound during your presentation/screen share. Let us know if this corrects your issue.
