For versions of XAudio2 with an IXAudio2SourceVoice::GetState() that offers a
flags parameter, we can use XAUDIO2_VOICE_NOSAMPLESPLAYED, since we don't
need this information in our current calls. According to MSDN, this makes the
the call about 3x faster.

If 'SDL_OpenAudio' is called with 'obtained == NULL', 'prepare_audiospec' performs a bad 'memcpy' with the destination and source pointing to the same block of memory. The problem appears to be on in 'SDL_OpenAudio', which calls open_audio_device with 'obtained = desired' when 'obtained == NULL'. 'open_audio_device' cannot deal with 'desired' and 'obtained' pointing to the same block of memory but can deal with 'obtained == NULL'

In SDL_wave.c, BEXT wave files with "bext" instead of "fmt " are choked on
if (chunk.magic != FMT) {
SDL_SetError("Complex WAVE files not supported");
was_error = 1;
goto done;
}
BEXT files http://en.wikipedia.org/wiki/Broadcast_Wave_Format actually playback the same as regular waves. All they have is (A LOT OF) extra header info.
To open them, just SKIP the "bext" chunk, and the "fmt " chunk will be a couple of hundred bytes later.
The "fmt " chunk is also bloated, but if you skip past the extra information to the "data" chunk, there is nothing different about a BEXT wave file than a "normal" one.
You can then load the data and proceed as normal.

Attached is patch from the OpenBSD ports tree to add 24-bit support to the sndio backend and to make use of the sio_open() option SIO_DEVANY.
