Missing playback device

I have a new docking station (Caldigit TB4) connected through TB4/UBS4 to my laptop (Dell XPS 9310). There are speakers connected through the docking statation, and they work well with other laptops.

When I run aplay -l I see the the device listed

**** List of PLAYBACK Hardware Devices ****

Still, nothing shows up in the list of Playback Devices, even when showing all inactive devices. I share the screenshot from the Audio settings panel; the output from pacmd list-sinks is aligned

I tried manually loading the module with pactl load-module module-alsa-sink device=hw:2 but I get a failure "Failure: Module initialization failed"

Anything else I can try to get the playback device?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
