Hub multi-port mistook for an external monitor when headphones plaggued in

I bought this hub, and, whenever I plague my headphones in, the computer thinks I got an external monitor (see attached screenshot).

I tried with different headphones and the result is the same. I have a DELL XPS 13 PLUS, and Ubuntu 22 on it.

I also found this related question but no solution was provided.

Thanks!

Two monitors

No solution was provided in the other Q&A you linked because there isn't one: https://askubuntu.com/a/1358263/1210606 It's an hardware quirkiness unrelated to the OS.

@ChanganAuto in fact, the answer is provided in that other question: the issue is with the hub, not Ubuntu.

@zwets Exactly, that's what I said while agreeing with no actual solution being provided, other the implicit get another device.

@FdA How do you know? Occam's razor - https://en.wikipedia.org/wiki/Occam%27s_razor - when you have multiple customers on multiple OSes reporting this same issue in a very similar device it stands to reason the problem is the same. The negative reviews in yours mostly complain about the audio output not working or HDMI/VGA not working but the latter is probably from users who don't know their USB-C has no alternate mode.

Anyway this isn't really a problem, just a very minor annoyance. Just select "single display" and make sure you select the actual one. Be happy.

@karel if you look at my question, I already pointed out the same website. It actually doesn't answer as the hub is different and I don't see any similar comments on Amazon. As was saying, it might be the case due to Occam's razor, even if we didn't explore many other options.

@FdA OK, retracted.

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.
