Issue description

I'm experiencing an issue with miniaudio and pipewire on Linux which is causing a "SIGFPE (Floating point exception)" when loading audio is present in the code. The code will build fine, however. When running it will SIGPFE. I first experienced it using other language binding, expecting something to be wrong with it, however an important note here, I previously used popOS which doesn't use pipewire, but EndeavourOS(Arch) uses pipewire. So I decided to give it a try with vanilla C raylib and still experienced the same issue, and I'm not the only person with that issue as there is yet one more user on Raylib discord who experiences the same problem.

Removing any instances of audio from the code fixes the issue, although I haven't thoroughly looked which one is the main culprit for SIGFPE, but I would assume it's InitAudio.

There are multiple closed issues on miniaudio page that report issues with PipeWire & SIGFPE error, please see here.

The issue overall makes Raylib unusable with audio under PipeWire.

Environment

Arch Linux - EndeavourOS
OpenGL 4.6
AMD RX5700XT

Code Example

No reason to include my original code as it's of a binding, but it happens with the original C Raylib, used an example to test it:

#include "raylib.h"

int main(void)
{
    // Initialization
    //--------------------------------------------------------------------------------------
    const int screenWidth = 800;
    const int screenHeight = 450;

    InitWindow(screenWidth, screenHeight, "raylib [audio] example - Multichannel sound playing");

    InitAudioDevice();      // Initialize audio device

    Sound fxWav = LoadSound("src/test.wav");         // Load WAV audio file
    Sound fxOgg = LoadSound("src/test.ogg");        // Load OGG audio file

    SetSoundVolume(fxWav, 0.2f);

    SetTargetFPS(60);       // Set our game to run at 60 frames-per-second
    //--------------------------------------------------------------------------------------

    // Main game loop
    while (!WindowShouldClose())    // Detect window close button or ESC key
    {
        // Update
        //----------------------------------------------------------------------------------
        if (IsKeyPressed(KEY_ENTER)) PlaySoundMulti(fxWav);     // Play a new wav sound instance
        if (IsKeyPressed(KEY_SPACE)) PlaySoundMulti(fxOgg);     // Play a new ogg sound instance
        //----------------------------------------------------------------------------------

        // Draw
        //----------------------------------------------------------------------------------
        BeginDrawing();

            ClearBackground(RAYWHITE);

            DrawText("MULTICHANNEL SOUND PLAYING", 20, 20, 20, GRAY);
            DrawText("Press SPACE to play new ogg instance!", 200, 120, 20, LIGHTGRAY);
            DrawText("Press ENTER to play new wav instance!", 200, 180, 20, LIGHTGRAY);

            DrawText(TextFormat("CONCURRENT SOUNDS PLAYING: %02i", GetSoundsPlaying()), 220, 280, 20, RED);

        EndDrawing();
        //----------------------------------------------------------------------------------
    }

    // De-Initialization
    //--------------------------------------------------------------------------------------
    StopSoundMulti();       // We must stop the buffer pool before unloading

    UnloadSound(fxWav);     // Unload sound data
    UnloadSound(fxOgg);     // Unload sound data

    CloseAudioDevice();     // Close audio device

    CloseWindow();          // Close window and OpenGL context
    //--------------------------------------------------------------------------------------

    return 0;
}

I am the other user mentioned in this issue, I can confirm I have this same problem. I am on Artix(Arch) Linux using Pipewire.

I ran a program with valgrind and this appears:

Process terminating with default action of signal 8 (SIGFPE): dumping core
==16260==  Integer divide by zero at address 0x100C412152
==16260==    at 0x4966DEC: ??? (in /usr/lib/libraylib.so.4.0.0)
==16260==    by 0x49609FC: ma_device_init (in /usr/lib/libraylib.so.4.0.0)
==16260==    by 0x498CC9D: InitAudioDevice (in /usr/lib/libraylib.so.4.0.0)

I've noticed a SIGFPE only occurs when my sound output has not been active for a while.

If I open pavucontrol and then run the program, a SIGFPE does not occur

[orcmid]

Sounds like an un-initialized-variable problem that depends on a garbage value that is sometimes 0. Or maybe something that can legitimately be 0 and the code doesn't provide/defend for it. What does ma_device_init source code reveal about the division operation?

raylib is not using latest miniaudio yet, I have to update the library, maybe this issue is solved with a new version of miniaudio.

@conifer-dev @realtradam Just updated raylib to latest miniaudio v0.11.8. Please, could you check if this issue persists?
