You will be the one who will test gb.openal!
Don't hesitate to publich
the OpenAL example to the Gambas software
repository.

I test; you fix. :) Thanks everyone for the responses and fix to the code. Now that I got the very basics working (can load and play a sound) I'll start working on getting 3D positioning, doppler, etc. working and will put together a nice demo. When it's polished I'll upload it to the farm so others may benefit. Once that's done I'll begin replacing the SDL audio code in Sylph and put a video up on YouTube to show off the new audio capabilities. -- Kevin Fishburne Eight Virtues www: http://sales.eightvirtues.com e-mail: sa...@eightvirtues.com phone: (770) 853-6271 -- ___ Gambas-user mailing list Gambas-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user

...because we have to destroy also the audio context:
Alc.DestroyContext(AudioContext)

Fixed code attached.
However, one allocation is not freed... I don't know
what it is.
