Thanks.

I've been using USB DACs for quite some time now, and the Marantz
HD-AMP1 is my fourth one.

Here's how it is with Tumbleweed;

       $ cat /etc/modprobe.d/50-sound.conf 

       options snd slots=snd-usb-audio,snd-usb-audio
       # wn1q.DDMX92BGFe0:HD-AMP1
       alias snd-card-0 snd-usb-audio
       # fHJ1.nUBBZmosli0:USB Audio
       alias snd-card-1 snd-usb-audio

RM>   There may be mechanisms, especially in connection with pipewire, that

The combination described above enables digital playback.
