Is there a known problem with the new setup of Suse and sound controllers?
The Nvidia sound controller, the onboard sound controller and even a straight lineout to speakers no longer register at all in anything that I can find except hwinfo.out, which I saved at install but cannot find.
I find ‘sound controller’ can be an ambiguous term in the context of GNU/Linux and very difficult to understand what one is talking about.
Do you mean the ‘mixer’ control that is typically in the right hand corner of a desktop GUI (such as KDE) ?
Do you have sound on your Tumbleweed PC setup?
Have you Pulse Audio Volume Control (pavucontrol) installed, which some people also call a ‘sound controller’ ? If talking about ‘pavucontrol’ I know of no issues.
Not related to pipewire/pulseaudio perhaps?

All devices are managed by systemd. You may search for corresponding units:
**i3-4130:~ #** systemctl list-units --type device '*sound*'
UNIT LOAD ACTIVE SUB DESCRIPTION
sys-devices-pci0000:00-0000:00:03.0-sound-card0-controlC0.device loaded active plugged /sys/devices/pci0000:00/0000:00:03.0/sound/card0/controlC0

LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.
**2 loaded units listed.** Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

The errors reported are informal only. Sound is working here perfectly out of the box.
