Ok, that's good, that eliminates a whole class of possible bugs.

So scsynth is generating a correct signal internally, and it's getting
corrupted when it leaves scsynth via the PortAudio layer -- or possibly in
the MME layer (I don't know where exactly Audacity's "what you hear" option
is tapping into the signal).
Unfortunately my knowledge of SC/Windows usage of PortAudio is ... nil.
One other test would be to try a different driver framework (e.g. ASIO). If
the signal is bad in all drivers, it would point to PortAudio as the cause.
If it's bad in MME but fine elsewhere, then it's the particular interaction
between scsynth and MME (which also isn't happening on everybody's machine,
so it's hard to troubleshoot -- I have a student using SC 3.8 in Windows, no
similar problem :\ ).
