%%%--- Operating System, Graphics card ---
Radeon HD 5770

- Blender version with error, and version that worked ---

error: 2.65 r54257

- Short description of error ---

Surroundsound-File (.wav) crashes Blender in Game Engine

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

Load a Surroundfile into Logic Bricks Sound-Actuator.
Choose a Sensor (no matter which one -> take "Always" for instant effect).
Start Game Engine and play the file.

In my case Blender get crashed, even if i switch the output-settings and play around with 7.1, 5.1 and 4 Channels under OpenAL.
SDL will play Sound only in Stereo (mixed all channels together), other settings dont play, but at least will not cause Blender to crash.

I attached a Soundfile with 4 Channels: L R Lb Rb
It caused my Blender to crash under OpenAL, SDL dont like it to play in Surround.

%%%Let's check if Joerg can redo this!

A test with an official build (release from blender.org, or daily build from builder.blender.org) is always recommended though.%%%

%%%Have tried it with 2.64 release, 2.65 release and 2.65 r54257,
i switched from Soundcard to Onboard-Sound and have deactivated other output devices, but all the same.

Turning 3D-Sound on in the Actuator prevents Blender from crashing, but thats not the purpose.

Media-Player, Sequencer and Synthesizers dont seem to have problems with Surroundfiles on my PC.%%%

%%%Can you get a backtrace, please.%%%

Karja Krähwald commented

%%%Ok but may take a while.
Need to find instructions how to do so.

Please make a suggestion what tool i should use. Thank you.%%%

%%%It's not easy to get a backtrace on windows, it needs a debug build and we don't upload those anywhere, so best for a developer to look at this.

I could redo the crash and committed a fix for only the crash, the sound will not play yet. The crash happened in KX_SoundActuator.cpp, this lines returns NULL for m_handle which crashed later in the function, so I added a simple NULL check there.

m_handle = AUD_getDevice()->play(sound, 0);

The reason it returns NULL is because in AUD_OpenALDevice m_useMC is false. So this means the AL_EXT_MCFORMATS extension for multi channel audio is not available. Maybe we need to upgrade our OpenAL library?%%%

%%%I tried copying the soft_oal.dll from the latest soft-openal over the wrap_oal.dll we use and it makes playback of this file work.
http://kcat.strangesoft.net/openal.html

It seems that a year ago we reverted from soft-openal to the creative openal, because 3D sound support was missing? But as far as I can tell it works with this latest dll, though I can only test stereo.

%%%I wish i could follow your steps by myself, but i am a total beginner.
Thank you for your efforts in this case.

I am still trying to get a backtrace, if its still necessary at all.%%%

%%%I deleted wrap-oal.dll and added soft_oal.dll to my Blender directory.
Unfortunately it doesnt helped.%%%

%%%@Karja. The DLL needs to be named the same (and expose the same symbols of course)%%%

%%%Windows guys: Could you please make sure this doesn't happen with openal soft anymore?

http://projects.blender.org/tracker/index.php?func=detail&aid=30232&group_id=9&atid=498

If not I have nothing against switching to openal soft.%%%

I forgot to rename it.

Thanks a lot.%%%
