'Threat Engaged' sound needs to be seperated from the music

[aBarrow420]

As the title says, the Threat Engage sound need to be seperated from the music in the audio settings.

I like to mute the music when playing and really listen to the sounds of the game. However, if I do this, I will not be alerted of an imminent threat.

I would like to suggest two seperate sliders in the audio-settings. One for music and one for alerts.
