Sound crackling / distortion

[Tom Davis]

I'm resubmitting this because it's been nearly a week without even a
single reply.  I guess since nobody has even attempted to help me on
about 5 different forums and 3 mailing lists, my problem must be the
first of its kind ever.
------------------------------------------------------------------------
Hey, I have a problem with sound distortion when using my Audigy NX
(USB) soundcard in Fedora Core 3.  Sound works fine in Windows XP Pro. I
am using ALSA and I believe I have the latest RPMs installed for it (I
don't have the latest alsa-driver-* because it comes in some .bz2(?)
format that I don't know how to install from, since I'm a total newbie
to this.  I just got the latest RPMs I could find).  I have tried
changing settings in alsamixer with no results. If anyone knows how to
fix this I would really appreciate it.  This is the last glaring problem
I can see with my new Linux install, so I want to get it fixed so I can
stop using Windows, like I am now, just to listen to music.
