Music volume doesn't affect main menu music
Just had a quick look all though the MusicPlayer.cs and TitleUI.cs the latter does not effect volume directly and is always going though all the music methods it uses does not seem to change volume without using the volume multiplier everything in MusicPlayer uses logic like SoundProfile.SoundVolume * this.Volume or when the volume is being updated SoundProfileSoundVolume * volume
Found the issue in TitleUI.cs Profile used for intro music was VideoMusic, since it was linked to FMV000 Fixed in patch
That was the wrong fix and it removes the track completely, I neglected to test again. Pushed a hotfix. So this problem is still open.
