In multiplayer no matter the distance anyone can hear the sound effect as if they were the origin

Did you use a custom sound or a MC one?

In Singleplayer I also have the issue of having the Sound still playing when using an Ability for long, like the longer I use the Ability the more the Sound repeats while looping and sometimes it stops after a while ago

I used the default elytra sound

I've also noticed that when you try to make the sound looping it just does it as if its a repeating command block playing a sound repeatedly and it just results in the sound sounding really weird and glitchy
