Edit: please check further down the replies for my second explanation as due to a glitch the original one below doesn’t work for everyone 
@Emma_episode_03 I thought I’m make this topic so we don’t get flagged for going off topic in the other one 
Now I’m not the best at explaining so please ask if there is something you are unsure of
So guys some of you me included have asked how to make a story where sound can be turned on/off. There is a way to do this without making 2 separate scripts.
So first you will need to make a Character called VOLUME to enable/disable sound (Do not use this character in your point system apart from in the sound option)
Now before your story starts ask the reader if they want to add sound then use these choices
Narrator
Do you want to play with sound?
choice
“Yes” {
@VOLUME =1
volume sound 100 1
volume music 100 0
}
“No” {
@VOLUME =0
volume sound 1 1
volume music 0 0
}
Note: I’m using 1 1 for sound as the 0 0 wasn’t working for me.
Now you can start your story
Scene 1
music (music name) the reader will only hear this if they have turned the volume on.
(Continue story here with music )
music off
(add more to the scene if you want)
Now if you want to fade music out during a scene you will need to turn it back on again for the people using sound but not for those who want to play without sound,
this is where we need to use if/else
So
Scene 2
music (music name)
(Insert what happens)
fade your volume here using the volume X S
Now this is where you will turn it back on, you need to write
if (VOLUME =1) {
volume music 100 0
}
else {
continue
}
So altogether it will look something like this
(Note this is just an example and as I have no access to the portal I’ve made backgrounds And animation up 
)
Narrator
Do you want to use sound in your story?
choice
“Yes” {
volume sound 100 1
volume music 100 0
@VOLUME =1
}
“No” {
volume sound 1 1
volume music 0 0
@VOLUME =0
}

Lets go sightseeing
I would add the sound option to all of the chapters so the reader can turn them on/off when they want to
I will reply to this on how to add closed captions which can be really helpful for those playing with or unable to use sound
If there is any trouble when using, just message me.
Too much for to handle smh.
