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

The combination described above enables digital playback.
