Oh... that's really bad. I didn't have a clear idea what you meant by
"pulsating distortion."

Hm... key detail: "the file both looks and sounds clean in Audacity" -- how
was the "clean in Audacity" file produced? SC server recording? If SC can
produce a clean sine wave and write it to disk, that would suggest the
problem is somewhere in between SC's calculations and the soundcard driver.

And, the file you uploaded to soundcloud -- how was that produced?

Which version of SC did you install? If you have the exact download link
handy, that would help. I'll guess it's 3.8.0 64-bit, but it doesn't hurt to
confirm. (There are compiler differences between some of the versions, so I
think for this issue it's necessary to be very precise about this.)
