Option to fix bug #851 For some people setting the period size works better (and is what SDL 1.2.13 did), but for most people it's the same or worse. You can use an environment variable to pick which one you want.

13 If this function succeeds, it returns the given \fI\fBSDL_AudioSpec\fP\fR, filled with the audio data format of the wave data, and sets \fBaudio_buf\fR to a \fBmalloc\fP\&'d buffer containing the audio data, and sets \fBaudio_len\fR to the length of that audio buffer, in bytes\&. You need to free the audio buffer with \fI\fBSDL_FreeWAV\fP\fR when you are done with it\&.

15 This function returns \fBNULL\fP and sets the SDL error message if the wave file cannot be opened, uses an unknown data format, or is corrupt\&. Currently raw, MS-ADPCM and IMA-ADPCM WAVE files are supported\&.
