Access violation at alure2.dll from the call of my custom entity

[edgarbarney]

Hello

In my mod, one of the entities I created emits a dynamic sound. There's no problem with the vanilla sound engine. Works as intended. But when I try with meta audio, the game crashes.

I attached a debugger, tried to replicate the event and found out exception is thrown at alure2.dll, by the launcher.CPP

I was going to try to fix the issue by modifying MetaAudio source code but I couldn't find solution files. Edit: Just found out CMake files but I still can't find the issue.

If you need, here is my entity.

Are you using FLAC files or something like that?

[edgarbarney]

Nope. I was using a custom WAV file at first. But then I tried with vanilla sound files, OGG and FLAC files too. The same thing happened.

[LAGonauta]

Is it related to voice? Just noticed that !HG_GREN3 is crashing the game.

[edgarbarney]

I've tried with random vanilla ambient sounds, not voices tho.

[LAGonauta]

Can you check if this is still happening on newest release candidate? https://github.com/LAGonauta/MetaAudio/releases/tag/v0.3.0-rc1

[edgarbarney]

Yup. Still the same.

By the way, can you provide a dependencies list for this project? I want to try and refactor myself but I cannot build VS projects because of the dependencies.

[LAGonauta]

You will need VS2019 with C++, CMake support, Windows SDK, and C++ ATL installed.

These are my CMakeArgs: https://github.com/LAGonauta/MetaAudio/blob/8d07c1287311be55fc5b864b45c1669916f7f025/CMakeSettings.json#L10

You will need to put libsndfile somewhere: https://github.com/libsndfile/libsndfile/releases/ (i still need to update to 1.0.31, I did not know it was release already. Currently using 1.0.28)

And patch alure2 like that to use the built-in OpenAL Soft:

I think you can also install OpenAL Soft manually and use some CMake parameters, but I do not know how.

Remember to fetch the git submodules.

[edgarbarney]

Fixed.

Changed channel for EMIT_SOUND_DYN to CHAN_AUTO from CHAN_STREAM

[LAGonauta]

Cool 🙂 But I wonder why it was crashing 🤔

[edgarbarney]

Maybe streaming channel is reserved for music or something?
