OpenAL and buttons' rolloverSound

flavio · April 24, 2010, 7:20am

Hello, I’ve a problem with my code. I report a minimal example to show this. I’m using Panda 1.7.0.

If I run the following code, it crashes.

import direct.directbase.DirectStart
from direct.gui.DirectButton import DirectButton
DirectButton( rolloverSound = loader.loadSfx( 'foo.ogg' ) )
run()

Instead, if I run with fmod, it works:

from panda3d.core import loadPrcFileData
loadPrcFileData('', 'audio-library-name p3fmod_audio')
import direct.directbase.DirectStart
from direct.gui.DirectButton import DirectButton
DirectButton( rolloverSound = loader.loadSfx( 'foo.ogg' ) )
run()

The problem is that I prefer to use OpenAL, but it crashes. How can I solve this? Thanks!

Works for me…
Can you try on another PC?

You’re right! I tried on a Snow Leopard machine and there it works. What could be? I’m on a Windows Seven (64 bit) machine. The problem is that the application crashes without any message, so I have no hints to infer the reason.

Try setting your debugging output a bit more verbose:

Thanks! With FMod it works and I obtain (I copy only the audio part):

… and it crashes. I don’t understand the problem…

I can’t test at the moment, but can you try loading the sound before it is used? Like this:

import direct.directbase.DirectStart
from direct.gui.DirectButton import DirectButton
mysound = loader.loadSfx('foo.ogg')
DirectButton(rolloverSound=mysound)
run()

Thanks, I tried your code but it has exactly the same behaviour.
