[Bf-committers] Soundlib crashes game engine

[Peter den Bak]

Wouter,

According to Kester Linux causes an assertion, but windows just crashes.
The call sound_init_audio is probably meant to make sure the call
sound_stop_all_sounds goes right, but sound_stop_all_sounds is protected
against this by the variable ghSoundScene.

The KetsjiShell creates its own sound scene and therefore does not need
sound_init_audio. I suspect that the sound scene created by =
sound_init_audio
conflicts with the sound scene created by the KetsjiShell in the =
function
KX_Scene (in KX_Scene.cpp line 148).

In my experience during testing omitting the sound_init_audio also =
speeds up
the game engine, probably because blender only needs to take care of 1
single sound scene, and this improves the collision detection.

So, yes I'm pretty sure you can omit the sound_init_audio, and I tested =
it
thoroughly.

Regards,

Peter den Bak

I tried to reproduce the problem following your steps in bug 1415, but
nothing crahsed here on Linux. Nonetheless, the patch mostly looks good
to me, but are you sure the call to sound_init_audio should be removed?
