Why does my computer render digital music as if there was a big dust ball
on the stylus? Lots of rumble and "wind blowing" sounds. Other sources
sound fine and it is not the amp, speakers, or the PC audio
connection. I downloaded the latest "real player" 6.5x and it still
sounds bad. It once sounded good. What happened?

the thing about digital fidelity is that it copies very well (from the
integrity of the signal).  The problem also means any errors remain
and are replicated faithfully.  Digital fidelity only applies to the
copying process - it does not guarantee that your digital file retains
its integrity over a long period of time - which is more dependent on
your storage conditions and situations.

it looks as if your digital file has become corrupted somehow - where
did you store the digital file - under what kinds of storage format?
(if it was on floppy bear in mind floppy disks are subject to rust
(older generations) and mold (some versions), if it was on harddisks
(bear in mind harddisk surfaces have a chance to become damaged -
there exist a very small chance as well for even memory chips to
degrade in quality.  If the data has become corrupted - there is
hardly any chance for you to recover unless you have a master copy
somewhere for you to re-copy.
