. Performance boost (Completely non-blocking between Sound thread and CPU thread, in the meantime keeping them thread safe) . Both 32KHz & 48KHz sound can be handled properly now (But up-sampling is still not implemented, and I don't think any game requires it.) . Strategy adjustment When your PC is *NOT* capable to run the game at 100%: >> DSound Could yield more fluent sound than OpenAL sometimes, but you will lose the sync between video & audio (since audio is played before video to guarantee fluency) >> OpenAL Ensures video & audio are always sync'ed, but sound could be intermittent(to let slow video catch up) . Changed default frame limit to: Auto (Somehow this can dramatically decrease the chance of wiimote desync in game NSMB) git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@4724 8ced0084-cf51-0410-be5f-012b33b47a6e
