Decrease Music Volume (Battlefield: Hardline)

Hello everyone!
Tell me how to reduce, exactly reduce the sound of background music in the game? It's just a nightmare how loud it is, and how it interrupts the sounds of gunfire and dialogue, especially when playing with headphones.
This is not the case in the "sound" menu, and if you turn off the sound in the "radio", then only the songs on the radio seem to stop playing.
I remember there was a method in previous Battles that somehow reduced the sound, edited a file. Also did in CoDmodern warfare 3.
Who knows how to do this, please advise.
I have a pirated version, not a license, if that plays a role in this case.
Thanks to all kind advisers in advance!)
