Hi Roy. I don't know if I can help much. I looked on my FC3 install, and in.
/lib/modules/2.6.11-0.3.rdt.rhfc3.ccrma/kernel/sound/isa/sb  , the snd-sb16 
module is there.

It's worth checking in Control centre/Sound & Multimedia/Sound System, that 
the "Enable the sound system" box is unchecked, if it isn't, make sure to 
click on apply after unchecking it. 

Perhaps you'd post a few things.
cat /proc/asound/cards
cat /proc/asound/version
/sbin/lsmod    (to check out if the snd-sb16 is on the list, and to see if 
anything else is there that might be interfering with it) .
/sbin/lspci      (to see if there are, either onboard, or pci modem cards) I'm 
clutching at straws on this one, as I don't know if the sound driver on modem 
cards would result in these problems.

Leaving Jack out of the equation, does Alsa work? Can you play a music cd? Can 
you play a demo track in Hydrogen, with it setup to use Alsa, and not Jack? 
Try stopping and starting Alsa, and see if there are any error messages.
/etc/rc.d/init.d/alsasound stop
/etc/rc.d/init.d/alsasound start

It's worth also running ps auxw on the CLI. See if there's anything audio 
related running that you were unaware of.

You can have a look in /etc/sysconfig , under, class: Audio, to verify the 
driver for your card.

Probably all of this is of little help, but worth a look. It might just be 
best to get another card. A cheap SB Live, but make sure it's one using the 
emu10k1 driver, but as the SB16 is supported it should work, even though a 
bit old.
