Yeah this config is no good. Green outlines / low performance. I've been working with this for PAL(from PSDW), and even though the audio issues seem to be adressed by code, they aren't,
#cli
--vu1-di-bits=0
--vu1-mpg-cycles=800
--vu1-jr-cache-policy=newprog
--vu1-jalr-cache-policy=newprog...
No matter which configuration i use, and no matter if it's pal or ntsc i've had audio restarting issues. I really don't feel like downloading/patching the game again. Have you tried this and does the music constantly re-start?
