linux - Does SDL require any sound server like PulseAudio ...
https://unix.stackexchange.com/questions/59577/does-sdl-require-any-sound-server-like-pulseaudio-to-play-audio
It seems that SDL could run without X if a framebuffer is available. You could begin from the examples at SDL's page to check whether it's a problem of your ARM board, and you probably will need to do other debugging on your audio player program (I would think it's a codec issue).

SDL 2.0.22 will default to Wayland on Linux | GamingOnLinux

It's a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware. It has been announced that the SDL 2.0.22 will default to Wayland, preferring it over X11. This is another big step towards Wayland properly being a replacement for the old and crusty X11 everywhere.

Using SDL_Mixer lets you use multiple audio playback channels so you can play more than one sound at a time. This example is written using Linux. The code should also work under Windows, but it's up to you to set up your build environment and libraries. The first thing you need to have is a working build environment.
SDL :: View topic - ALSA/OSS linux audio driver priorities
https://forums.libsdl.org/viewtopic.php?p=9414
Hey, I recently found out that SDL prefers using OSS audio over ALSA audio in Linux. This is a bit of a problem on systems using ALSA's software mixing (dmix), because ALSA's OSS emulation doesn't do any software-mixing at all unless the OSS-using program is run through aoss, which results either in no sound or blocking other apps (including ALSA ones) from using sound while …
