What property in the Audio Source component would you increase to prevent background music from cutting out when sound effects play?

To prevent background music from cutting out when sound effects play, increasing the priority of the audio source is the correct approach. The Audio Source component in Unity has a property called "Priority" that determines the importance of that audio source relative to others. When multiple audio sources are playing at the same time, the audio system uses priority values to decide which sounds to play and which to drop if there are limitations on how many sounds can be played simultaneously.

By increasing the priority of the background music audio source, it ensures that it remains audible even when sound effects are triggered, which generally have lower priority values. This means the audio engine will preferentially keep the music playing while potentially reducing the volume of less critical sounds, like sound effects, or stopping them if necessary.

In contrast, adjusting volume would change the loudness of the audio and could still lead to cutting out if overall limits are reached. Pitch affects the speed and tone of the audio but does not influence the playback continuity relative to other sounds. SpatialBlend deals with how 3D the sound feels and does not impact the audio layering or prioritization.
