[SOLVED] Thunderbolt monitor audio not recognised

After scouring the different related topics I couldn't figure out why I'm not getting an audio card for my Thunderbolt-connected monitor.

Looking at this topic it seems my point of divergence from a better flow is that I'm never getting the " usb 3-1: Product: ThinkPad Thunderbolt 3 Dock USB Audio" message in dmesg.

Anyone know what it's about or what more information is needed?
Here's dmesg from connecting the monitor:

I use Pipewire and currently have two recognised sound cards, the built-in and an external USB-connected Behringer card. Here's /proc/asound/cards:

 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xec318000 irq 171
 1 [CODEC          ]: USB-Audio - USB Audio CODEC
                      Burr-Brown from TI USB Audio CODEC at usb-0000:00:14.0-3, full speed

Thanks in advance!

Re: [SOLVED] Thunderbolt monitor audio not recognised

Does the monitor contain an audio card? Maybe it simply uses the DisplayPort audio channel, does your hda-intel have some DP/HDMI profiles?

Re: [SOLVED] Thunderbolt monitor audio not recognised

The monitor has an audio output with a speaker connected to it, is it possible for it to have an audio port but not "card"? I might be misunderstanding some terminology, but I believe it should exist.
Are profiles in the context of hda-intel different from what pulseaudio considers profiles?
Here's the output of `pactl list cards` (installed for `pipewire-pulse`)
Looks like there are HDMI-related profiles, but I'm not sure what that implies.

Re: [SOLVED] Thunderbolt monitor audio not recognised

Ah, I now know what it means. Choosing the HDMI profile in pavucontrol makes the speakers work through the monitor.
I'm still confused by why it's considered HDMI and not some Thunderbolt-related audio. Would have made sense to me if it were DisplayPort related.
It works, though. Thanks!

Re: [SOLVED] Thunderbolt monitor audio not recognised

With "card" I meant that it advertises itself as an independent audio interface to the computer. As you found out you have the other option. It advertises itself as a monitor with speakers and receives audio through the displayport connection.

I'm still confused by why it's considered HDMI and not some Thunderbolt-related audio. Would have made sense to me if it were DisplayPort related.

It is not thunderbolt-related because the audio is sent as part of the DisplayPort protocol / alternate mode of Thunderbolt 3/usb-c that is used. Why all digital monitor audio channels are called HDMI instead of DP/HDMI I don't know. Maybe the initial implementation was for hdmi and it was adapted for DP, but the descriptions were never updated.
