audio won't play in ppt

Hello, my name is Mark and I just subscribed to Envato. I downloaded a video file wth a .mov extension. I tried to play it in ppt, but there was no audio, just video. I converted it to an mp4 file and still no audio. I know my audio works in ppt, as I have another audio file that works perfectly in the same presentation. Can someone tell me what I’m not doing correctly? Thanks in advance.

If you buy a video clip from Videohive, then their music usually goes separately, you only get a video clip.

You can check description down below the item. Perhaps there is a link to the used music track

when I downloaded the file I was able to play it and hear the music, but when importing it to powerpoint, only the video, no sound.
