3d audio on 1.5.2

Scripting Issues
1

Has anyone been using 3d audio with great success?

When I was using 1.4.2 my 3d audio worked fine, but since I switched to 1.5.2., I am having some problems.

For one thing, I get this error:

:audio(warning): stereo sound /c/Panda3D-1.5.2/Projects/Sound/001_air.MP3 will not be spatialized
:audio(warning): stereo sound /c/Panda3D-1.5.2/Projects/Sound/002_cam.MP3 will not be spatialized
:audio(warning): stereo sound /c/Panda3D-1.5.2/Projects/Sound/004_beat.MP3 will not be spatialized

and the quality of the first sound has diminished.

Secondly, after I switched to 1.5.2, I added two other sounds and attatched them to objects, but I only hear a very faint, strange choppy noise when the camera gets close to the objects.

I will be thankful for any input on these issues.
Here is part of my code:

Shouldn’t this work properly?

What audio manager are you using?
Check your Config.prc. Does it say p3fmod_audio or p3openal_audio? If either doesn’t work, consider changing it to a library that does work correctly.

3

It’s p3openal_audio.
How do I change it to a library that does work correctly?
Where can I find info on these libraries?

4

You can try changing it to p3fmod_audio.

5

I tried p3fmod_audio, and now one of my I can’t hear one of the sounds that previously played.
