alsa-project/alsa-ucm-conf issue #210 was edited from tekstryder: Per @perexg request, filing a new issue after testing git master branch changes for the ALC4080 and finding any profile(s) to be missing/nonfunctional. USB ID: `0db0:1feb` In version 1.2.7.2 of .../ucm2/USB-Audio/Realtek/ALC4080-HiFi.conf I need to change: - Define.SPDIFIndex "3" to Define.SPDIFIndex "2" For proper playback via S/PDIF. After that change the release version is working great as far as I could test. Please let me know if I can provide any other useful information. Attaching the output of `alsaucm -c hw:2 dump text` Attaching the output of `pactl list sinks` [ucm-dump.txt](https://github.com/alsa-project/alsa-ucm-conf/files/9463734/ucm-dump.txt) [sinks.txt](https://github.com/alsa-project/alsa-ucm-conf/files/9463784/sinks.txt) Issue URL : https://github.com/alsa-project/alsa-ucm-conf/issues/210 Repository URL: https://github.com/alsa-project/alsa-ucm-conf
