Re: There is no music In live mode

@QooLV  Try removing options.ini from Documents\Electronic Arts\The Sims 4.  When you launch the game, a new file will spawn with default settings.  You'll need to redo all your in-game settings, but hopefully the music will work again.  If it doesn't, you can just put the old options.ini back if you prefer, rather than changing all your settings.

If removing options.ini doesn't help, please clarify which music doesn't play: is it music from the radio, in-game sound effects, or both?
