Sound not working

Hi,

I’m on Unity 5.4. If I set my 3D sounds for example to min 10 and max 500 I can’t hear any helicopter sounds, even if I stand next to it. But when I set it to min 100 and max 500 I do hear sounds. But then I can hear the helicopter at the same volume level anywhere on the map.

If I look on the audiograph the red line in the audiograph won’t move when I walk closer towards the helicopter.

What happens when you set the min to like 50?
