The AAudio driver implemented pause/resume by dangerously locking the audio devices. If there was an audio hotplug event or a background thread tried to interact with the audio system, this could cause deadlocks.
Simple DirectMedia Layer is a cross-platform development library designed
to provide low level access to audio, keyboard, mouse, joystick, and graphics
hardware. It is used by video playback software, emulators, and popular games
including Valve's award winning catalog and many Humble Bundle games.
More extensive documentation is available in the docs directory, starting
with README.md. If you are migrating to SDL 3.0 from SDL 2.0,
the changes are extensively documented in README-migration.md.
