AudioSource.PlayClipAtPoint in Unity5 doesn't increase volume

Hello,

In Unity 4 I used

AudioSource.PlayClipAtPoint(clip, Camera.main.transform.position, 2);

To play a one shot sound at double volume, and it was working fine. But now in Unity 5 the volume doesn’t seem to get higher than 1. Is there is something new I don’t know? Did they put a limit to 1? I have to increase the volume of my audio files with external apps?

The range is from 0.0 to 1.0
