How do I mute sounds without stopping sounds from playing?

So I need to have a mute option for my game, and Set Silent mutes the game just fine but creates a problem of it's own; some conditions in the game's event sheets are tied to whether a sound tag is playing, and Set Silent stops the sounds from playing altogether, and thus breaks them.

I could manually replace all of those with other specific conditions, but I was wondering if there was an easier solution to maintain the gameplay that relies on those tag conditions even when the game is muted.

Thanks for the response!

I don't think that would work because 0 just means the default audio level, but it did make me think and I just figured out that you can just say Set Master Volume db to -Infinity and it works!
