alsa-project/alsa-ucm-conf issue #219 was opened from nphil: Hello, This motherboard uses realtek-alc4080 chipset, going by some of the other related issues I found the USB ID as follows: `$ lsusb | grep 0db0` `Bus 001 Device 003: ID 0db0:005a Micro Star International USB Audio` Added `005a` to my USB-Audio.conf (running Manjaro) and rebooted. I now have audio through my optical port working just fine. Not sure how to do a pull request properly, just thought I'd share this here.
