I'm trying to get the choppy sound sorted as well (using Project Justice as a template). I followed the first two pages of advice, but it won't fix.
Let me list what I've got and what I've done so far, so maybe one of you can point out what I'm missing or haven't tried.

These are the plugins I'm using:
Settings for the audio plugin:

After all that, I've tried 2048, 2044, and 4096 in the config file. I still get scratchy audio, specifically the music.
