Steps to reproduce:

1. Add a sound (default: local sound, manual trigger, not playing, looping, not muted). 
2. Change sound type to area sound 
3. Play area sound
4. Move listener inside area sound

Expected behavior: I should hear the sound just like local or global sounds.

Actual behavior:  I don't hear the sound at all. It only becomes audible after adjusting the sound's volume of the sound in any way. Mute/Unmute and any of the other controls don't fix the problem.

Notes:

• For reproduction the order of the steps 2 and 3 doesn't matter. 
• Keep in mind that the problem also occurs when I open a project with existing area sounds.
  • If the listener is inside the area sound and I play the sound then it's audible. If I move the listener outside and inside again afterwards then it's not audible again unless I change the sound's volume.
