I'd guess the audio issues have to do with the hardware as well - though I
did not test on any of the "problem" systems enumerated in your link.
All my SoaS tests were on the same desktop computer - i.e., same hardware.
As noted, some versions of Record worked flawlessly (SoaS), others with
glitches (major or minor) and/or artifacts, and some not at all (either no
save, no play, even no load - as in Record v64 with Blueberry, "failed to
These results would seem to indicate issues *in addition* to hardware
