Hi ​@Megan Brits, 

I understand you're encountering an issue where the video sound is on during preview, even though you've turned off the sound.

I tested this on my end using the Video properties settings on the Prototype tab, and it seems to be working as expected for me.

I also noticed you've already submitted a support ticket for this.

To help us take a closer look at the specific sound issue you're facing, could you please send a video recording demonstrating the behavior in reply to your ticket confirmation email?

This will really help our team understand exactly what you're seeing and investigate the cause of the issue.

Thanks,

Hello! 

Thanks for the response I think the issue was because it was a prototype in Slides - as soon as I moved it over to a design and not slides it worked on my end!
