Description Daniel Knobe 2013-11-11 15:34:58 UTC 
Hallo,
I have found a bug in SDL 2.0.1 and may be below.
Calling the function
SDL_PauseAudio(false) 
twice under some WinXP configurations leads to a problem. The second call never returns.

I know this function is deprecated but I think the compatibility layer should work, too^^.

Best regards
Daniel

Hey Ryan, can you look at this really quick?

Recommend to close this bug as no repro.

Added test automation for this case which can be run using
  ./testautomation.exe --filter audio_pauseUnpauseAudio
and cannot verify this issue on Win7/cygwin build.

$ ./testautomation.exe --filter audio_pauseUnpauseAudio

This works in the test case Andreas created. Please reopen this bug if you're still seeing the issue.
