Hi I am no expert on sound either, but here goes my 5 Den 24.11.2024 kl. 22.47 skrev Marc Chamberlin via openSUSE Users:
Thanks Masaru Nomiya for taking the time to help me out. I will edit out some of the original comments of mine and intersperse my replies after your queries below.

[...] I've never seen anyone use so many sound devices like you. LOL, well actually some of the sound devices you see came with the Gigabyte motherboard as features.
My system has at least as many sound devices as yours - and they did all work perfectly well before, when I was on Pulseaudio - and also now after my change to Pipewire. The only problem I'v experienced with many devices is that sometimes the system attempts to be helpful, and end up sending the sound to a device with no speakers connected.
MC> https://en.opensuse.org/Sound_troubleshooting This is not designed for use with multiple sound devices. I disagree, it has nothing to do with the device count. But that guide is for when you use Pulseaudio, and I suspect that in your upgrading, your sound system have been changed to Pipewire.
Check with rpm -qa | grep pipewire-pulseaudio I not - please ignore the rest of my message :-)
Hmm, OK but it was the best troubleshooting document I could find.... If you know of a better document please let me know. Although your system might already have been changed by the update, I would suggest that you try following
https://en.opensuse.org/openSUSE:Pipewire to make sure that any leftovers from your previous Pulseaudio install is removed. Also check for any leftover Pulseaudio config files that Pipewire might interpret different. You can try a systemctl --user status pipewire.service as your normal logged in user. To see if your you have a running Pipewire. Mine is like: klaus@msien:~> systemctl --user status pipewire.service ● pipewire.service - PipeWire Multimedia Service Loaded: loaded (/usr/lib/systemd/user/pipewire.service; disabled; preset: disabled) Active: active (running) ... If are running pipewire, I suggest to install qpwgraph to show your devices and how sound is routed between devices. There is still bugs(1) in how Pipewire and KDE works together, but in the overall picture I find Pipewire easier to work with. -- Klaus 1)https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/3832
