IEC958 is the last column when using alsamixer. I would use alsamixer
to mute IEC958 just to be sure. Gnome volume control may not have worked
for me.
I then added the following lines to my /etc/modprobe.conf:
install snd-ens1371 /sbin/modprobe --ignore-install snd-ens1371 &&
/usr/sbin/alsactl restore >/dev/null 2>&1 || :
{all one line - don't split up}
remove snd-ens1371 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove snd-ens1371
{all one line - don't split up}

I added these lines to my modprobe.conf. Runlevel 6 and 5 show my mixer
settings being saved and restored.
I was having problems with changes that I had
made to my mixer getting changed back. This seemed to fix it. Someone
told me that FC4 didn't need the modprobe.conf lines, however I found
they made a difference. -- Bill
