Remove Sound Icon/Volume Control from any slide

I have come across this problem over the years as well, where I have a slide that I have to hide the seekbar but then the volume icon is still there. I have used the frame.xml solution in the past but that can be a pain to update every time you publish. Add this to a JavaScript trigger on the slide where you want to hide just the volume icon:
$(".cs-icon.volume-icon").hide();

And if you need to add it back in a later slide:
$(".cs-icon.volume-icon").show();
