Been bashing my head around this for a couple of hours, and finally got it to work
looks like the default sound class for all imported sounds is “master” i found it on engine>engine sounds, so a ticked the “apply ambient volumes” on it
i also didnt know that i could select the sound class by opening the sound asset double clicking it
when i did it, it started working, the one thing i dont see on this tread is the size of the audio volume, my camera is far far away, 20.000 units, so when i make the audio volume huge to overlap it the volume works
thanks a lot for the info above
