Let me preface this by saying I've spent hours scouring posts on sound cards and tried
everything I've found, to no avail. Details below. So I'm posting.
I did a yum FC3->4 upgrade, which broke the sound, so I continued on and did FC4->6.
Sound still broken. I've read tens of posts suggesting fixes, but none work. My sound
card is an Ensoniq 1371 (*which worked fine in FC3*). The system properly recognizes
it, and the appropriate kernel module apprears to be loaded. lsmod says:

On other PCs, I've had to unmute the equalizer in alsamixer to get sound
to work, but not here: no equalizer appears in alsamixer, kmix or the gnome
volume control utility. What _does_ appear is a 3D control, plus switches
for line in, mic, aux, etc., and those infamous two IEC958 (-1) switches.
Oddly, if I turn on IEC958-1, I get the well-known hiss, but BELOW the hiss
I can hear whatever sound file I'm playing, very faintly. This suggests that
the sound card really is recognized and the kernel is doing the right thing
with it.
I'm willing to believe that for some reason I'm not allowed to access a volume
slider anywhere and it's just set very low. But what could cause that?
Misc. notes:
* I've tried the "plug a headset in for the line detector" trick -- no good.
* Telling Kmix to add a volume control tray does nothing.
* Killing the external amplifier option doesn't do anything.
* "alsamixer -V all" doesn't add anything new.
* Yes, I killed artsd, which always caused problems.
* There's no /etc/rc.d/init.d/alsasound -- should there be?
* I'm not finding any more suggestions via Google.
Somebody please help before I put a large screwdriver straight through the
case...
