Changing the volume of the dialogue sound effect when you choose an answer

So I am quite new to the developing world and I'm making my first RPG, but I have a problem. So I have a house, where there is a piano and a static character sitting in front of it (playing). I composed some piano music that plays in the background, but the music is written in the range of "piano" - "pianissimo" (in other words, it's silent). It's meant to be silent so I'm not looking for a way to increase it's volume but you can talk to the guy playing the piano. It gives you 3 options and whichever you choose, the answer is "...". But when you talk to him, there is a beeping short sound effect whenever you highlight a different option or press enter. It disturbs the music very much, so I was wondering where (if possibile) could I change the volume of it or maby even mute it. Thanks, MrFishManify

If you go into the database you will see a page with all the default sound effects on (I think it's the System tab, not at my PC right now). You can change it to no sound or replace it with one you prefer, and you might be able to change the volume there too. I think it's F9 to access the database. Good luck! :)

Thank you very much, works :D

If you only need to silence the sound effects for this one NPC (or multiple places but not everywhere), you can do so using script calls.

I haven't tried it myself but I think something like $data_system.sounds[n].name = "x" will work, where n is the System SE number that you want to set (you can check the correct number by going to Modules: Sound in the script editor) and x is the name of the SE that you'd rather play.  You can do the same with volume and pitch rather than name.  Be sure to set these back to their original values at the end of the event.

This is only necessary if you still want the cursor sound effects to play elsewhere - if you want to silence them throughout your whole game, mostly useless' solution will work better.
