Restore previous behavior of empty SDL_AUDIODRIVER trying all drivers. The recent change to make SDL_AUDIODRIVER support comma-separated lists broke the previous behavior where an SDL_AUDIODRIVER that was empty behaved the same as if it was not set at all. This old behavior was necessary to paper over differences in platforms where SDL_setenv may or may not actually delete the env var if an empty string is specified. This patch just adds a simple check to ensure SDL_AUDIODRIVER is not empty before using it, restoring the old interpretation of the empty var.
Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valveās award winning catalog and many Humble Bundle games.
More extensive documentation is available in the docs directory, starting with README.md
