Why do headphones recognize as a speaker?

Question

Audio

The problem is that the headphone jacks on the front panel are broken. Well, I decided to stick them in the back. As a result, my headphones are recognized as a speaker. The sound has changed, it is impossible to play at all. Worth Windows 10
PS If something is a complete zero in computers and I don’t understand how these drivers are or what to do with them

Answer 1

Speakers are technically no different from headphones. Image and text are defined by default. Rear connector - speakers, front - headphones. Also, the sound can't be any different. Only if the settings are different. Open the program that comes with the sound driver, for example for Realtek - Realtek HD Audio. See settings, adjust. And in the dialog in the picture, you can change the text and icon manually to anything (from the list of icons)

Answer 2

Because the computer cannot determine what is connected there. And the rear speaker jack. The hardware type is configured manually in the driver program.
