Laptop Internal Speakers: speaker audio-driver conflict. The audio driver does not initialise the laptop's speaker playback path correctly.

The distinguishing clue

Speaker playback fails after a driver change although the audio device remains listed.

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 exact audio hardware ID, manufacturer driver and update history. If confirmed: Restore the matching signed audio driver or roll back the confirmed faulty change.

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.
