[SOLVED] Pulseaudio SSL2 analog stereo duplex is not available

Pulseaudio was working well until yesterday, when it suddenly broke - now only Analog Stereo Input and Analog Stereo Output are available but not the combination of those.
The relevant part of pacmd list-cards:

index: 0
	name: <alsa_card.usb-Solid_State_Logic_SSL_2-00>
	driver: <module-alsa-card.c>
	owner module: 6
	properties:
		alsa.card = "3"
		alsa.card_name = "SSL 2"
		alsa.long_card_name = "Solid State Logic SSL 2 at usb-0000:03:00.0-8, high speed"
		alsa.driver_name = "snd_usb_audio"
		device.bus_path = "pci-0000:03:00.0-usb-0:8:1.0"
		sysfs.path = "/devices/pci0000:00/0000:00:01.3/0000:03:00.0/usb1/1-8/1-8:1.0/sound/card3"
		udev.id = "usb-Solid_State_Logic_SSL_2-00"
		device.bus = "usb"
		device.vendor.id = "31e9"
		device.vendor.name = "Solid State Logic"
		device.product.id = "0001"
		device.product.name = "SSL 2"
		device.serial = "Solid_State_Logic_SSL_2"
		device.string = "3"
		device.description = "SSL 2"
		module-udev-detect.discovered = "1"
		device.icon_name = "audio-card-usb"
	profiles:
		input:analog-stereo: Analog Stereo Input (priority 65, available: unknown)
		input:iec958-stereo: Digital Stereo (IEC958) Input (priority 55, available: unknown)
		output:analog-stereo: Analog Stereo Output (priority 6500, available: unknown)
		output:iec958-stereo: Digital Stereo (IEC958) Output (priority 5500, available: unknown)
		off: Off (priority 0, available: unknown)
	active profile: <output:analog-stereo>
	sinks:
		alsa_output.usb-Solid_State_Logic_SSL_2-00.analog-stereo/#0: SSL 2 Analog Stereo
	sources:
		alsa_output.usb-Solid_State_Logic_SSL_2-00.analog-stereo.monitor/#0: Monitor of SSL 2 Analog Stereo
	ports:
		analog-input: Analog Input (priority 10000, latency offset 0 usec, available: unknown)
			properties:
				
		iec958-stereo-input: Digital Input (S/PDIF) (priority 0, latency offset 0 usec, available: unknown)
			properties:
				
		analog-output: Analog Output (priority 9900, latency offset 0 usec, available: unknown)
			properties:
				
		iec958-stereo-output: Digital Output (S/PDIF) (priority 0, latency offset 0 usec, available: unknown)
			properties:

I tried to set the profile to duplex using

pactl set-card-profile alsa_card.usb-Solid_State_Logic_SSL_2-00 output:analog-stereo+input:analog-stereo

but that fails saying 'Failure: No such entity'

Right now I am unable to participate in meetings because of this, so any help would be very much appreciated!

Re: [SOLVED] Pulseaudio SSL2 analog stereo duplex is not available

A kernel regression with certain USB cards, downgrade to 5.19.8 and follow https://bbs.archlinux.org/viewtopic.php?id=279758 and https://bugzilla.kernel.org/show_bug.cgi?id=216500

Re: [SOLVED] Pulseaudio SSL2 analog stereo duplex is not available

Yup, that's right! I first switched to LTS, but it seems like this bug is present in both versions.
But downgrading to 5.19.8-arch1-1 indeed helped, thanks!:) Will be following the issue.
