Game crash from failing to initialize audio device

It looks like it's an issue with the surround sound. I'll post a workaround to the steam discussion to see if it works.

libGDX is still using lwjgl 2, which doesn't have much support. I'm not sure we'll be able to do much until libGDX supports lwjgl 3. Does't look like there's much progress on this.

Hey, I'm the guy who reported this on Steam.

My setup is a bit unorthodox, but I had no problem with any other program thus far. I have two sound cards:

• Creative Sound Blaster Live CT4830, using drivers from kX Project
• MSI FM2-A55M-E33 integrated, using drivers from AMD CCC

Also, I'm using Aster to segregate the two sound cards (and other peripherals) into one workspace each. The game works in neither of those.

Regarding the suggested workaround from Steam:

For a workaround, assuming you're in Windows, in the sound panel right click on your device and click "Configure Speakers". Try changing your device from "Surround" to "5.1 Surround" or "Stereo".

Both of the workspaces already use stereo.

Hope this helps.

Interesting. From your error log it would appear that it's trying to configure your audio as 7.1, as the following lines say there are 8 channels.

AL lib: (EE) DoReset: Unhandled channel config: 8 -- 0x000000ff
AL lib: (EE) DoReset: Unhandled extensible channels: 8 -- 0x000000ff

Someone else has reported a similar issue with the kX driver and OpenAL. Could you try what they suggest in this link

Setting the default device from Master Mixer to Wave Out 2/3 worked.

Thanks for following up, @hauzer :-)

I wonder if we can still harden the game to avoid a crash. Might be tricky if it happens within LWJGL, all we do is:

new LwjglApplication(new SolApplication(), c);

Since failing to initialize sound shouldn't technically be fatal maybe we can catch org.lwjgl.openal.OpenALException and retry with a soundless configuration? Revealing some angry looking "WARNING: Sound disabled - " in the game UI or so.

Closing this since it's probably not relevant anymore after LWJGL updates and such.
👋 @hauzer If you'd like then feel free to re-test the latest changes and re-open this if it still occurs
