open AL unexpected message

[ka0s420]

Hello,

I've recently come back to my project after about a month long break. Since then, i've started to recieve an error message in the console  - AL lib:: (EE) MMDevApiMsgProc: Unexpected message: 49385

However, the application still runs, but then after about 3-4 mins or so, the app crashes with "no symbol file loaded for openal32.dll" error.

At this point, the app is only streaming music, the dll is in the folder with the game, and as stated runs fine for about 5mins. The crash happens both when running through visual studio, and when running the compiled app.

in vs, it also says: Exception thrown at 0x00EA448D (openal32.dll) in Wetware.exe: 0xC0000005: Access violation writing location 0x0000BAC2. which to me looks like a null pointer error, but again, this doesnt make sense, as the music and dlls etc don't move and everything stays in scope.

game crashes even when there is no music playback.

Sounds like you're not using the openal32.dll that is shippee with SFML.
Have you copied the DLL next to your exe?

[ka0s420]

high, yes, i'm using openal32.dll that came with sfml 2.3.2, and like i said this was working before without a hitch. the dll is most definitely next to the exe, yes.

I'm racking my brain trying to think of things that I could have altered on my machine that have changed the way it runs somehow, but can't think of anything.

This reminds me of the warning I am getting

http://en.sfml-dev.org/forums/index.php?topic=20053.0

I also get the crash 4 mins or so after leaving things to run

[ka0s420]

Yes it does sound very similar. I found your post when originally looking for the problem on google. But figured it may be different because of the warning numbers and also because, if my memory serves me, you built sfml yourself, whereas im using a release build. Im thinking that i'll try and download a new or newer version of sfml and replace the dll, see if it is possibly corrupt somehow. Will report back if anything works.

[eXpl0it3r]

So what's the call stack when it crashes?

Correct on different warning number but i didnt build sfml myself.

Ill report a call stack next time this happens.

Hope that one of these was what you were asking for.

[eXpl0it3r]

Do you have a working audio device? Any troubles while playing sounds/music in other applications? Is your audio driver uptodate?

[ka0s420]

yeah, my audio is working. I use FL studio regularly to record and edit music. I watch videos and listen to music regularly without incident. Also gaming ofc The drivers are up to date and I have no other problems with audio.

[Hapax]

This is a slightly old topic but the issue doesn't seem here to have been resolved and I have also experienced this error (again, with a slightly different error code).

Any idea if this is an OpenAL problem? I can't seems to find anything in OpenAL's documentation describing what to do in the case of "Unexpected Error" or even that it exists.

To ka0s420 and Erdrick:
Which sound devices were being used when this error appears?
Did the release or debug build tend to last longer before the crash?

[mtvee]

I'm getting this too, win 10, audio card is fine, using openal.dll that ships with sfml. The following is from the console.

You get this when you do what exactly?

[mtvee]

You get this when you do what exactly?

I load a couple of ogg files into SoundBuffers. I'm not even playing them or even create an sf::Sound. Just load two buffers.

[eXpl0it3r]

Are the SoundBuffers initialized in a global scope?
