Only MIDI ports of an audio interface recognized, but not the audio ports

The device (ZOOM UAC-2) is definitely detected by the system, as I can successfully use its MIDI ports. But, the audio side is nowhere to be found. The interface has a “Class Compliant Mode”-switch, and a quick googling reveals that others have had it working out-of-the-box. If I dual-boot to Windows, I am able to use the device no fiddling of drivers.

What I suspect is that the device is marked as a MIDI device only. I have another DAC which has no MIDI ports and it worked straight away. It is not currently plugged in, but I suspect that the confusion of having them both plugged in may have been the cause for this. I am using Pipewire.

Would anyone happen to know how to force flag the device as audio or something similar? Thanks in advance. I wouldn’t mind losing the MIDI-capability in exchange of audio, if that is the price.

EDIT:
Actually, the device is listed under audio, too.

Audio:
  Device-1: NVIDIA GA104 High Definition Audio vendor: Palit Microsystems
    driver: snd_hda_intel bus-ID: 1-10:8 v: kernel pcie: chip-ID: 1686:f028
    class-ID: 0103 gen: 3 serial: <filter> speed: 8 GT/s lanes: 16 link-max:
    gen: 4 speed: 16 GT/s bus-ID: 01:00.1 chip-ID: 10de:228b class-ID: 0403
  Device-2: ZOOM UAC-2 type: USB driver: snd-usb-audio
  Sound API: ALSA v: k6.1.9-1-MANJARO running: yes
  Sound Server-1: PulseAudio v: 16.1 running: no
  Sound Server-2: PipeWire v: 0.3.65 running: yes

But it is invisible in any audio related GUI, DAW or system settings?

Also, it is listing PulseAudio on addition to Pipewire, but I thought that I had removed it. Cold this be due to mismatch in having both, PulseAudio and Pipewire installed?

EDIT2:
In qpwgraph the MIDI-ports are tagged as “ALSA”, and not Pipewire. Is this the culprit, that the device is not recognized by Pipewire? If I plug in the second DAC, it is correctly labeled to PipeWire and works immediately.
Sorry, I am new to this.

EDIT3:
The Zoom has no “PLAYBACK” or “CAPTURE”-streams, compared to the other DAC and my GPU.

So, how would I add them?

I tried this with a live-usb, it worked instantly. After I booted back, the device works. I have no idea what is going on: I had done multiple reboots, reconnects and flicked the switched to every possible direction: now just coming back from the live-usb helped. I will mark this solved, but I am baffled.
