Laptop Internal Speakers: incorrect headphone detection. A jack-sense state keeps speaker output disabled after a headset is removed.

The distinguishing clue

The system still reports a wired headset with nothing plugged into the socket.

Checks before an assessment

Play the same familiar recording at a moderate level, checking left and right balance. Note whether headphones work and whether the speakers are selected as the output.

Stop point: Loose metallic debris near speakers can contact the motherboard.

Workshop confirmation and repair

Device-level check: Compare headphones, balance settings and firmware sounds before inspecting speaker wiring.

Targeted check: Compare the reported jack state and inspect the sensing path. If confirmed: Repair the jack-sense fault or its confirmed driver setting.

Repair boundary: Replace the damaged speaker or repair its amplifier or cable path.

Related cause to rule out

When the built-in speakers are silent while another selected output plays normally, also consider Laptop Internal Speakers: speaker output selection or mute before choosing a repair.

Checks after the work

After repair or replacement, check left and right channels, speech, music, volume range and sleep.
