If I do the following, I can get the audio on the optical and headphones:
------------------------------------------
mkdir /usr/src/alsa-ucm-conf
mkdir /usr/src/alsa-ucm-conf/current
cd /usr/src/alsa-ucm-conf/current
git clone https://github.com/alsa-project/alsa-ucm-conf
cd alsa-ucm-conf/
mv /usr/share/alsa/ucm /usr/share/alsa/ucm_bk_01
mv /usr/share/alsa/ucm2 /usr/share/alsa/ucm2_bk_01
# -P keeps symobic links; R copies dir
cp -PR /usr/src/alsa-ucm-conf/current/alsa-ucm-conf/ucm /usr/share/alsa
cp -PR /usr/src/alsa-ucm-conf/current/alsa-ucm-conf/ucm2 /usr/share/alsa
cp /usr/share/alsa/ucm2/USB-Audio/USB-Audio.conf
/usr/share/alsa/ucm2/USB-Audio/USB-Audio.conf.bk01
gedit /usr/share/alsa/ucm2/USB-Audio/USB-Audio.conf &
#in realtek-alc4080
# in Regex, replace 0414:a00e with 0414:a012
------------------------------------------
The optical and headphones work except I have three issues:
1. When I reboot, in the Rocky sound settings, the computer defaults to
"hdmi/displayport-built-in audio". To get the optical port, I have to
select "digital output (s/sdif) - usb" in the settings.
2. When I plug in headphones for the first time, to get the audio to
switch to the headphone jack, I have to select “headphones - usb audio”
in the settings. If I unplug the headphones, the settings switch back
to hdmi. Then if I plug the headphones back in the headphone works.
3. I have kvm switch that switches usb mouse, usb keyboard, usb
printer, and hdmi between this linux box and a windows laptop. When I
switch from linux to windows, I get a pop on my speakers. This is weird
since the optical port is built into the motherboard and the optical
port only goes between the linux box and speakers.
Do you know if any of these issues are easy to fix? If not, I can live
with the issues.
Also, should I submit the USB-Audio.conf change as a feature request(
except adding 0414:a012 instead of wiping out the other motherboard)?
Thank you for your help. I've been fighting with these issues for a
long time.

With Rocky Linux 9 (clone of RHEL 9), I do not get audio of the front
headphone jack or the optical output on the back. I do get audio out of
the line out on the back. The front port does not work with Rocky Linux
8, Ubuntu and Fedora, and I did not test the optical. With Windows, the
front jack works as expected with the realtek driver installed, and I
did not test the optical on Windows.
The output of /usr/sbin/alsa-info.sh is here:

https://github.com/alsa-project/alsa-ucm-conf/blob/master/ucm2/USB-Audio/USB-Audio.conf
has more If.realtek-alc4080 entries. When I copied the
If.realtek-alc4080 section into
/usr/share/alsa/ucm2/USB-Audio/USB-Audio.conf and
/usr/share/alsa/ucm2/conf.d/USB-Audio/USB-Audio.conf, and after I
rebooted, I get the same performance.
The configuration for your hardware version is missing in UCM.
Change 0414:a00e string in Regex (If.realtek-alc4080) to 0414:a012 for
a quick test in USB-Audio.conf. And yes, use the latest
USB-Audio.conf, Realtek/ALC4080.conf and Realtek/ALC4080-HiFi.conf
files from github.
