There appears to be a general issue with the audio with the Mac port of PCSX-R. The audio crackles on any PS1 software I run. I'd estimate - probably 95% fullness of audio, it is not 'that' bad of an issue really.
I have tested every possible audio, visual and emulation setting combination possible without any resolution. Tested ISO's only, CD's only (All PAL-UK source, not tested NTSC games), BIOS's (SCPH7502 UK plus the built in BIOS).
If I run EPSXE through VirtualBox with these same games and configurations, I get no issue at all and emulation is perfect. Only PCSX-R is the only running process on my system using 100% of one of my processor core so I can't see any external issue from the OS.
Spec: iMac Mid-2011 27" - 3.4Ghz Core i7, 6gB DDR3, 2gB Radeon 6970M, OSX 10.7.2, SSD/HDD disk drives.
I have attached a movie demonstrating my configuration (speedily) and the sound issue, it is not just on in-game video, it happens constantly, everywhere, even when not in a in-game video. The movie FPS has been purposely reduced on the file to fit the 4mB upload limit. I actually get full FPS with the emulation. The audio you will hear is how I hear it.
Thanks for the wonderful work you are doing on this emulator.

Oh, by the way, here's a silly question: could it be that the sense of the High Compatibility Option got inverted somehow? To me a single thread doing both sound and graphics updates via successive function calls and using busy-waiting for frame delays hardly sounds like an "async plugin interface"; if anything, it sounds synchronous.
