For some strange reason, after converting a PowerPoint presentation to a video the sound speaker symbol appears in my newly converted video, even though I put hide during slideshow. Does anyone have an idea of what could be the problem? I think this happened after getting the last version of office, Office 2016. Because the other videos I have were converted with the older version of PowerPoint and I didn't experience problems with it. I would be really appreciative if anyone is willing to help me or at least tell me what the problem is.
