No music/sound glitch playing coop online

Hey all,
Not sure if there is already a post but my wife and I have completed a playthrough with fl4k and amara and didn’t have any issues like this, but: she started a Moze and joined my game while I was still playing fl4k and the music and some other sounds left the game. She quit and joined again and same thing. She joined as Amara and everything was fine but later came back as Moze and sounds left after a few minutes again. Today we are both playing Moze and really the dialog and shooting are the only sounds around right now, no music and some other sound effects are gone? Anyone else having similar issues?
