I'm getting a noisy output file from Csound.  When I simply try to
create a sine wave with the code from the introductory tutorial, the tones
have a strange backgound noise.  I thought the noise might be coming from
the sound card, but from careful listening to the file played forward and
backward, I can hear that the noise is in the file itself.  It occurs only
when the instrument is actively producing sounds.  I'm using Windows NT
and playing the files through either the "media player" or "sound
recorder."

Has anyone else had this problem?

I tried all kinds of things like matching the "Kr" value with the "Sr"
value and changing the sampling rate to 44.1K (In fact, increasing the
sampling rate actually allowed more high frequency components in the
noise).  Where could it be coming from?
