Use of fake_stream in SDL_RunAudio

SDL Development

Hi,

I’m trying to get the playback latency as low as I can for
audio playback.

I’m using Linux, and noticed that there is a delay in SDL_RunAudio while
stream gets set to audio->fake_stream, instead of getting the
buffer.

The below patch seems to work fine in my system (it tries GetAudioBuf
before the main loop); is there any reason this will not work ?

Thanks,
Bill May
