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.

https://github.com/alsa-project/alsa-ucm-conf/blob/master/ucm2/USB-Audio/USB... 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.
