Sound Rate ranges from 8000 to 22050, in the future of course it will be raised to 44100. You can now choose the number of buffers, and to enable or disable sound. Atani advices not to re-enable it if a game is running. Here we go again with this scanlines thing, now fullscreen mode supports them and doesn't freeze anymore. The Dolphin 2 in windowed mode with scanlines below.
Transitions now are much nicer, good to know.
Finally now sound in fullscreen mode has been fixed, and the emu doesn't crash anymore, and even Atani didn't know why. Well, I guess it's all for this nice beta.
