Best Answer

Your speakers may be detected as unplugged which causes them to be ignored.

Temporary fix:

  1. sudo apt install pavucontrol
  2. Run pavucontrol
  3. Configuration tab > Profile > Analogue Stereo Output (unplugged) (unavailable)

Speakers should work but it will reset when headphones are unplugged or system rebooted.

Permanent fix:

  1. sudo apt install alsa-tools-gui
  2. Run hdajackretask
  3. Parser hints > jack_detect = no
  4. Apply now
  5. Install boot override
