Pause streaming music (Spotify from Firefox) when a video in a slide plays then resta

[J_Man]

Hello,
I have PowerPoint playing a presentation that runs in a loop while Spotify plays in the background on Firefox. I would like to add a video slide to this presentation with a MACRO? that mutes the sound from the browser so the video's audio can be heard then restarts the sound from the browser after the video plays. I've searched around but can't find a way to do it. Any suggestions would be greatly appreciated.
Thanks very much!

To the best of my knowledge that is not possible.

Thanks for looking at this, I believe you are correct. I've posted this to a few boards and nobody has a way to do this. I'll just have to record music and play it as an audio file.

Always good to mention when you cross post BTW. It prevents people working away when there is a solution elsewhere.
