I don't think I am having conversion problems since I have all programs
set to 48k though. Based on the experiences of others recounted here so
far, I would anticipate that my 48k recordings going from N1MM over VAC
and through PSDR all set to 48k would work.
But it sounds like there's a serious buffering problem because it's
seriously choppy on output when I do that.

I thought so- I believe you having the same sample rate up and down
conversion issue that I was having on digital modes, and that 44.1
k is not where you want to be. See if you can find out what sample
rate N1MM uses for its audio files. Record the wavs at a multiple of
that sample rate. I "forced" the VAC sample rates and the Windows
sample rate to a multiple of the sample rate used in one of my digi
programs.
Since many Flexers use N1MM, they can contribute the sample rates for
their wav files and for VAC.
