Ubuntu paired with Soundblaster faces issues when sorting data.
Sorry for that name. Your PC uses Ubuntu 20.10 with a Soundblaster Audigy card as the main audio source. After turning off built-in sound, the HDMI output from the 1660 Super works fine. However, during reboots, device order in /proc/asound/cards changes, which affects sound routing. To fix this, you set Audigy as the default in /etc/asound.conf. If you restart and it switches to card 0, you’ll lose audio because Nvidia takes precedence. With extra peripherals like a macro pad, MIDI slider, webcam, and mic, you need to manage their order manually or specify them explicitly in the config. There’s no built-in option to force Audigy to always be first regardless of number.
This Arch Wiki section applies to Ubuntu as well. It explains how to configure the default sound card.
I've covered most of what was mentioned. The issue lies in /proc/asound/cards altering card order during reboots, which isn't addressed in the article.
You set the indexing of your audio devices to remain consistent upon startup. That matches what you were looking for.
