No way to turn off sound.

Why is there no way to turn off/mute sound in this game? This is one of the most basic options in literally every game I've ever seen or played, a lot of people have their effects/music/ambient/dialogue volume set up in very specific ways in order to maximize enjoyment/immersion while playing.

Sometimes you'll find yourself in a position where you have to play without sound for a while. So I'm just supposed to drag every slider to 0 volume individually, screwing up my sound setup so I can carefully adjust them back to their original positions afterwards?

Maybe if the sliders had numbers people could make note of those and easily adjust their volume back to their specific needs after turning it off.

Or you know:

[x] Disable sound

Something a 5 year old could hardcode into the game in less than an hour.

Maybe it's just me.

''Turn the sound off in windows'' is not a solution. And anyone suggesting this is just standing in the way of progression and making the game better/more enjoyable/more elaborate.

Add --nosound to the shorcut of the path of exile (standalone), but if you are on steam you'll have to right-click the game in the library select propertis and click set launch options where you just type in that command.
