[Sugar-devel] Record Activity (audio)

[Art Hunkins]

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 
load plugin").

These results would seem to indicate issues *in addition* to hardware 
variations.
