I tried a very naive implementation last night. It has potential but it is still a bit jerky. Because the sound callback only fetches 512 samples at a time, while a complete frame is 735, you end up getting back-to-back emulation updates too quickly. I'm also getting some weird performance coupling between the main and audio threads that wasn't there before and can grind the emulator down to single digit frame rates permanently if a hiccup occurs somewhere (like loading a state).

We just need to be smarter about buffering. Hopefully over this weekend, we'll have a new system in place. It's definitely doable and I think it's the way to go considering that many users might only get 50 FPS in some games. That's enough to be playable but right now, audio is unbearable at anything below 60 FPS. This should alleviate that.
