Well it's hard enough for me to learn.. 
I thought I would mention a couple things:
1. Music mod has been removed again, hopefully for the last time. However "Disable streaming audio" still remains in the DSP_HLE configuration which was a part of Music mod.
2. Since the major Dsp work, the Resident Evil Zero audio fix is now broken. Despite the recent improvements in Dsp emulation, some audio still will not play without this fix or will cut off midway through playing. Perhaps a way will be found to fix the audio for these games without the need for this fix/hack, until then probably trying to find out what broke this fix might be more viable.
