If I pull the jack half a millimeter, the "detection" fails and both play sound.
I could try another desktop. Faulty jack socket?
That sounds likely given the half a millimeter wiggle.
Other possibility is worn insulation ring on the male plugin. Not as likely, but if your headphones are old, something to look at.
Nope.
This is not a hardware problem, it is a software problem.
It is not hardware muting the headphones, it is the software which mutes them. The hardware simply tells (correctly) that the headphones are plugged, and the software reacts silencing everything.
If I wiggle out a bit the jack, the hardware does not tell the software that the headphones are connected, and thus both headphones and loudspeakers get sound.
and then later
There is a hiss in them, which proves they are connected to the hardware.
Sorry, I get the impression that you're drip feeding new information into the thread, perhaps as you remember it. But it makes it very difficult to help to diagnose. I'm not going to go back and reread every post in the thread and try to keep it all straight in my head. If you can post a summary with all the pertinent information in a single message then I'll read that and see if I can think of anything. But I would hope that in the act of writing it all out in an organized way, the solution will occur to you :)
