d0ac9f02aa Start Android Audio Thread after audio buffer and AudioTrack are ready. 
Also, it starts the Audio Thread from the native side, putting the code in line
with other backends.

a164f89158 Workaround older libpulse that fails in pa_context_new() with a NULL appname. 
Newer libpulses do sane defaults if you pass a NULL there. In lieu of a
proper way to specify this in SDL at the moment, this will do.

Fixes Bugzilla #1119.

e1bbdec6b8 Mac: Codify SDK and OS requirements, and clean up. 
This #errors if you're using an SDK or deployment target that is less
than 10.6 and 10.5, respectively, and cleans up uses of
MAC_OS_X_VERSION_MIN_REQUIRED and MAC_OS_X_VERSION_MAX_ALLOWED according
to those requirements.

83c211c2bc Make winmm and directsound audio targets robust against unsupported formats. 
It now tries to make sure the hardware can support a given format, and if it
 can't, it carries on to the next best format instead of failing completely.

f6250318c6 Protect SDL_PauseAudio*() with the audio callback lock. 
Otherwise, you can pause audio and still have the callback running, or run
 one more time. This makes sure the callback is definitely stopped by the
 time you return from SDL_PauseAudio().

0cbdae6cb5 Explicitly write silence to the audio device while it is paused. 
This is what SDL 1.2 did; we'll do this properly (add a method for the target
 driver to pause) when I rewrite all this code after the official 2.0 release.

Fixes Bugzilla #1857.

1dfa68f250 Fixed bug 1949 - Pulseaudio 32 bit audio formats support 
Matt Scheirer

Pulse has supported (since version 0.8, at least) 32 bit audio formats that are now becoming available in SDL2. This patch adds those format conversions to the switch clause in the pulseaudio backend.

        22385, 24623, 27086, 29794, 32767
    };
    Sint32 delta, step;

    /* Compute difference and new sample value */
    step = step_table[state->index];
    // Some Code
}

Here step_table array have the state->index, which might be negative, so it is unsafe to assign this index to step_table array directly.
There would be a check before that to confirm its value.

...into this...

    if (Failed) {

64ffa4ad74 Fixed bug 1679 - Error in buffer size setting in Haiku/BeOS audio driver 
PulkoMandy

Just like in SDL, audio buffer sizes for BeOS and Haiku BSoundPlayer are sized
in bytes, not frames. SDL was feeding the wrong value, leading to buffers
smaller than expected and weird behaviour in some unsuspecting programs
(noticed it in HivelyTracker but others are likely affected as well. The fix is
fortunately very simple

619c1d8cd0 Fixed bug 1632 - iOS CoreAudio doesn't close 
C.W. Betts 2012-10-28 19:42:01 PDT

I noticed when looking through the CoreAudio code of SDL 2.0 that there was a
fix me wondering how iOS closed the audio system. While working on my own audio
code on PlayerPRO, I discovered that Carbon's component code was replaced in
the audio subsystem with Audio Component Services.
