Hello, I need to configure DDL 5.1 for my Asus Xonar DX card so I can send 5.1 channel audio through an optical SPDIF connection to my receiver. The instructions I found are quite outdated and disrupted the setup completely. I've also checked the older forum thread and another discussion on Ubuntu help, but they seem to be even more dated. Would anyone be willing to review and improve this guide? I'm just a basic user of Ubuntu. My system runs Asus Xonar DX with Ubuntu 18.04, and currently only receives PCM stereo output by default. Thanks in advance.

If unsure, Ubuntu relies on systemd and you should adhere to its guidance. Verify all channels are unmuted per the instructions provided.
