  Fixed bug 4642 - Rework SDL_netbsdaudio to improve performance Nia Alarie The NetBSD audio driver has a few problems. Lots of obsolete code, and extremely bad performance and stuttering. I have a patch in NetBSD's package system to improve it. This is my attempt to upstream it. The changes include: * Removing references to defines which are never used. * Using the correct structures for playback and recording, previously they were the wrong way around. * Using the correct types ('struct audio_prinfo' in contrast to 'audio_prinfo') * Removing the use of non-blocking I/O, as suggested in #3177. * Removing workarounds for driver bugs on systems that don't exist or use this driver any more. * Removing all usage of SDL_Delay(1) * Removing pointless use of AUDIO_INITINFO and tests that expect AUDIO_SETINFO to fail when it can't. These changes bring its performance in line with the DSP audio driver.
