Rebooting didn't help any. I didn't know what to try next,
so I did the easy thing: use Yast Sound to delete the device
configuration and then reconfigure it.
Fortunately that fixed it and the sound device is now working.

I had not use Yast Sound to configure the device. Maybe
pipewire did that automatically?  although I never ran
pipewire.

Anyway, it is all good now.  Thanks for your help.
