Rotating Soundbar Speaker Assembly
The audio signal is transmitted via a flexible ribbon cable that undergoes torsional stress every time the laptop lid is adjusted. Over hundreds of cycles, the copper traces within the hinge's flex cable develop fatigue cracks, leading to intermittent resistance and signal noise (crackling). Replacing the soundbar assembly restores the integrity of the signal path across the rotational axis.
