Audio device not being listed in Switchboard and Wingpanel

[Zieg]

My audio interface (NI Komplete Audio 6 MK2) is not listed and cannot be selected in both Switchboard and Wingpanel.
However pavucontrol detects the device properly and allows volume adjustments and profile selection.
The device outputs sound normally and works as expected otherwise.

I have checked the source of switchboard-plug-sound and it looks like the list of devices is published based on Ports in Pulseaudio.

Running pactl list sinks indeed shows that there is no Ports section for Komplete Audio 6:

Sink #449
	State: SUSPENDED
	Name: alsa_output.usb-Native_Instruments_Komplete_Audio_6_MK2_10564816-00.analog-stereo-out-ab
	Description: Komplete Audio 6 MK2 Analog Stereo 1/2
	Driver: PipeWire
	Sample Specification: s32le 6ch 48000Hz
	Channel Map: front-left,front-right,aux0,aux1,aux2,aux3
	Owner Module: 4294967295
	Mute: no
.....
		device.vendor.name = "Native Instruments"
		alsa.card = "0"
		alsa.card_name = "Komplete Audio 6 MK2"
		alsa.long_card_name = "Native Instruments Komplete Audio 6 MK2 at usb-0000:00:14.0-6.3.2.3, high speed"
		alsa.driver_name = "snd_usb_audio"
		alsa.mixer_name = "USB Mixer"
		alsa.components = "USB17cc:1870"
		alsa.id = "MK2"
		device.string = "0"
	Formats:
		pcm

On LinuxMint with older kernel (5.15) and slightly older version of PulseAudio the Ports section is present:

		device.description = "Komplete Audio 6 MK2 Analog Surround 2.1"
		module-udev-detect.discovered = "1"
		device.icon_name = "audio-card-usb"
	Ports:
		analog-output: Analog Output (type: Analog, priority: 9900, availability unknown)
	Active Port: analog-output
	Formats:
		pcm

Purging PipeWire from the system and changing the profiles does not seem to change the Ports section availability.

Need further help with troubleshooting this.

TL;DR: Pulseaudio output is missing the Ports section for the device, thus it is not detected in Switchboard.
