x870-A no S/PDIF output audio (ALC4080)

alsa-project/alsa-ucm-conf issue #468 was opened from SentryII:

Hi all, I've been searching for hours for a fix for this and im posting this as a last resort

I've checked under If.realtek-alc4080 in the USB-Audio.conf and the X870-A is not listed IDVendor is 0b05 IDProduct is 1b9b 0b05:1b9b

Line-Out works fine, issue is with Soundcard 2 USB-Audio Which is using optical / S/PDIF

I've attached the alsa-info output below

Thank you for your time [alsa-info.txt](https://github.com/user-attachments/files/17876970/alsa-info.txt)
