Description g1529208 2015-04-11 17:04:22 UTC 
The following does not work with the default audio driver on my system (xaudio2):

ASSERT (SDL_OpenAudio (&audio, nullptr) == 0);
SDL_PauseAudio (false);
// <Later>
SDL_CloseAudio ();
ASSERT (SDL_OpenAudio (&audio, nullptr) == 0); // <- this fails the assert

Checking SDL_GetError, "XAudio2: XAudio2Create() failed at open." is returned.

The above code works fine (as it should) with the directsound audio driver.

This bug prevents one from changing the audio format/sample-rate (by reopening the device with the new format/sample-rate), or from closing the device for a while while no sound is expected.

Coming along to this a long time later, I can't get this to reproduce, but we made heavy fixes to this code since then, so I'm assuming we fixed it.

(Also, we're about to dump XAudio2 entirely, with a new WASAPI renderer for Vista and later, and DirectSound remaining for WinXP...and winmm for XP users with bad DirectSound drivers. :)   ...so you should be good to go here in 2.0.6 in any case, if not already in 2.0.5).
