I recorded a screen capture video using Canvas studio. However, once it was uploaded, the sound is missing.

I've recorded multiple screen capture videos and the sound on those works fine (except sometimes the mic will stop working mid-video and I get a notification letting me know).

This time there was no notification and I believe the mic was working fine (green lighting up signal). I've tried downloading the video, playing it from a course page, and playing it from the studio page, all with no luck. 

Has anyone had this issue happen before? If so, is there a way to recover the audio from the file?

Thank you in advance!
