I haven't experienced any issues with choppy sound on any of my three Win7 x64 machines using my unofficial 1.41 build.
FireBrandX's issue sounds like either a bad audio driver or something wrong with his particular hardware. It wouldn't surprise me if the other Nestopia users reporting this problem have the same faulty audio driver or hardware.
Anyway, for anyone reporting this issue (or any other issue) in the future, it's incredibly important that you provide detailed repro steps (including all your Nestopia settings, running fullscreen or not, what ROM(s) you are using, and your hardware configuration) so that developers like me can actually reproduce the problem. If you don't provide enough information and we can't reproduce your problem, then there's nothing we can do to investigate it or fix it.
Just for the record, I am playing NTSC roms on an NTSC PC with the monitor refresh set to 60fps, VSync enabled, fullscreen, timings set to "synchronize to screen refresh", and sound latency set to "1". This is using my 1.41 unofficial release.
My primary desktop hardware:
Windows 7 amd64 RTM + all latest Windows Updates
Gigabyte GA-X58A-UDR3 motherboard (Intel X58 chipset)
HPET (High-Precision event timer) enabled and set to "64-bit mode" in the BIOS
Intel Core i7-920 CPU overlocked to 3.2 GHz
ATI Radeon HD 4890
Integrated Realtek HD Audio
all latest drivers/firmwares/BIOSes installed
