I have a powerpoint presentation which includes a video, and I'm meant to present this through Skype (or Teams - but I have no way to test this on Teams before the day I'll be presenting)
Initially when testing I had some problems with the other person seeing the video at all: the picture was just stuttering a lot and no audio. After going through media compression the video plays smoothly, but they still receive no audio whatsoever (whereas voice is 100% fine).
The volume of the video is set to "medium" on the powerpoint presentation, so it's not that. I am wondering if it's a compatibility issue with Skype (but it seems strange, it's a normal 15-second MP4 file), or if somehow Skype is only accepting sounds that come through the microphone (ie my voice) rather than those that come from the computer itself (which would be ever stranger).
I have run out of ideas on how to fix this.
