If the laptop is powered on with a jack plugged in, independently on what is plugged, the jack is treated as a microphone jack.
Initialize the capture source so that by default jacks are treated as headphones jacks. This will also prevent pop noises on boot in case headphones are plugged in since setting/unsetting mic-in as input source causes a pop noise.
