Cannot initialize SDL audio system

[ghost]

Debian testing

Installed deps including

• libsdl-mixer1.2
• libsdl2-2.0-0

Output when I run a background from a directory

Irrlicht Engine version 1.8.4 Linux 5.2.17-rt7 #1 SMP Tue Oct 22 07:22:41 MDT 2019 x86_64 Using renderer: OpenGL 3.1 AMD BARTS (DRM 2.50.0 / 5.2.17-rt7, LLVM 9.0.0): X.Org OpenGL driver version is 1.2 or better. GLSL version: 1.4 Cannot initialize SDL audio system

I have also tried running as sudo

I don't know if this will help but on arch I had to install the 32bit version of sdl

What is the output of dpkg --list | grep sdl? Take in mind that you need SDL (not SDL2) and SDL_mixer. I guess your installation is x64? I'll try to build it in debian testing as soon as I have time and get back to you.

I got the same issue on Debian Buster (NVdia Graphics card). Would really love to see it work!

[Almamu]

@themultiplexer I'll need some extra information on why this happens. Can you run dpkg --list | grep sdl and copy the output here? I guess you're using the 64 bit version of debian?

I actually fixed the problem tonight: I found out that MixInit() returns error code 9 which means: Mixer not built with MP3 support

So i pulled SDL_mixer and compiled it myself: If libmpg123 is found, SDL_mixer automatically compiles with MP3 support.

hg clone http://hg.libsdl.org/SDL_mixer/
hg checkout SDL-1.2
sudo apt install libmpg123-dev
mkdir build
cd build
../configure
make
sudo make install

Finally I had to add the SDL header path to CMakeLists.txt so it finds SDL_types.h, etc.

set(SDL_INCLUDE_DIRS /usr/include/SDL)

I hope this fix works for you @bennybenjaman

[Almamu]

That's a little weird. I'm adding some extra information to the "Cannot initialize SDL audio system" so It's easier to debug in the future, and I'll investigate why the debian's SDL-mixer doesn't support MP3. I'll keep the issue open for now so I can at least update the compilation instructions.

I had success with removing the system libsdl-mixer1.2 and libsdl-mixer1.2-dev and instead installing binaries from https://www.libsdl.org/projects/SDL_mixer/release-1.2.html with alien and dpkg. This seems to be easier than rewriting linux-wallpaperengine to use SDL_mixer 2.0.

Old thread but I'm experiencing this issue as well.

do not that libsdl-mixer1.2 requires libsmpeg-dev for mp3 support whereas libsdl2-mixer requires libmpeg123

I'm pretty sure it's about the package options you're presented with when installing ubuntu, because mp3 support itself is not GPLd, or at least it wasn't years ago. but I haven't had any time to try in ubuntu/debian yet.

[Nova1545]

Im getting the same error where SDL Mixer isnt built with mp3 support, is there a fix for this or a guide to building SDL Mixer with mp3 support?

I don't have any guides to build SDL_Mixer for ubuntu. SDLmixer is not a really complex library, so it should be somewhat easy to do. Check their release page and the documentation they have on the build process, that should get you started: https://www.libsdl.org/projects/SDL_mixer/release-1.2.html

[Almamu]

This issue is irrelevant now. SDL 1.2 is no longer in use. There's still issues with audio, but because of different reasons.
