Figma removed audio from uploaded mp4s

I work on a product that has a sound library that plays during specific interactions. I built a component with embeded mp4s that had audio in them so people could include sound in their prototypes to better mimic the product experience. I had it all set up and working for me locally at the end of my day today and shared it with my collegues only to get notes that no one could hear it. When I went back a few hours later to double check I found that it no longer worked for me.

I checked the history and nothing changed between my work and when I checked back later. What changed? Did Figma re-encode my files, break my project, and REMOVE the sound?

Hi there,
