They have no way to specify this in a way both SDL versions recognice it. Best option to solve this problem would be to convince the SDL developer group to integrate a patch for SDL2.0+ which not only uses SDL_AUDIODRIVER=pulseaudio but also respects the "old" backend name like SDL_AUDIODRIVER=pulse

http://pulseaudio.org/ticket/866 We mentioned this in Bug # 1013, in regards to SDL_mixer, at one point. The gist is that we need to tell PulseAudio "wait until you've definitely played what we asked you to and get back to us" and it waits way too long.

From the SDL_Quit documentation: ``` You should call this function even if you have already shutdown each initialized subsystem with SDL_QuitSubSystem(). If you start a subsystem using a call to that subsystem's init function (for example SDL_VideoInit()) instead of SDL_Init() or SDL_InitSubSystem(), then you must use that subsystem's quit function …

"If you built your own SDL, you probably didn't have development headers for PulseAudio (or ALSA), so it's trying to use /dev/dsp, which doesn't exist on many modern Linux systems (hence, SDL_Init(SDL_INIT_AUDIO) succeeds, but no devices are found when you try to open one). "apt-get install libasound2-dev libpulse-dev" and rebuild SDL...let the configure script find the new …

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 doesn't need PulseAudio per se; however, it can use PA if it's available. 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).
