It may not change the settings automatically.

Try going to "Sound Settings" -> "Output" and choose the device you want to output to. It solved my problem with an HP USB headphones.

Probably, your Headphone Jack Sense is turned off..

Try this:

  • Open Terminal.
  • Type in alsamixer.
  • Locate and navigate to "Headphone".
  • Press m.

This should turn on your Headphone Jack Sense.
