How to mute the "Recording is On" sound?

I want to mute the audio which plays when the recording starts. How to do that on the server?

I´m trying the same, or at least change that audio to another one.
But I can´t find the audio file in jitsi server.

You can find the recording in “/usr/share/jitsi-meet/sounds” directory. Are you planning to put an empty sound with the same name there?

Thanks, no I replaced the recording with another one in other language
