Remove Sound Icon/Volume Control from any slide

for every script where you see the "$" char in the code, you need the library "jQuery"

jQuery is not included in Storyline anymore, since

• January 21, 2020 (Storyline 360)
• June 16, 2020 (Storyline 3)

but jQuery is not needed, you can do it with pure javascript

hide volume button

document.getElementsByClassName("cs-volume")[0].classList.add("hidden");

show volume button

document.getElementsByClassName("cs-volume")[0].classList.remove("hidden");

tested with modern player and classic player - so it should work with Storyline 3
