Laptop Headphone Jack: contaminated headphone socket. Debris or residue prevents the plug contacts from seating cleanly.

The distinguishing clue

A compatible plug stops short or audio crackles without visible cable damage.

Checks before an assessment

Compare a known compatible wired headset at a moderate volume. Note whether the plug is detected and whether one channel, both channels or the microphone fails.

Stop point: Broken plug fragments should not be dug out with the battery connected.

Workshop confirmation and repair

Device-level check: Test a known headset, inspect the socket and compare detection across restart.

Targeted check: Inspect the unpowered socket without pushing material deeper. If confirmed: Remove serviceable debris safely or replace a contaminated jack.

Repair boundary: Clean or replace the jack, or repair its sensing circuit after software routing is excluded.

Related cause to rule out

When the plug sits loosely or one channel fails immediately after a pull or impact, also consider Laptop Headphone Jack: physical headphone-jack damage before choosing a repair.

Checks after the work

After repair or replacement, check both channels, microphone where supported, plug detection and movement.
