Question regarding a custom command in Haruna media player

Help
1

I’ve just reinstalled my system (Ubuntu 20.04) and I forgot the custom command in Haruna to make it start muted. I think it was in the form of “start mute yes” but I this didn’t work.
Can anyone please remind me the external command for starting the player on mute?
