Audio synchronized with gameplay

[JMC47]

What he said. But, I'll expound a little bit. It was removed because asynchronous audio was crashing a ton of games that relied on audio for various events, timings, and other things. Synchronous audio fixes (literally) hundreds of crash bugs and is the more accurate way of emulating audio, but unfortunately people with slow computers won't get full speed audio. Considering the first goal of an emulator should always be playing the games correctly, this was deemed a non-issue.
