Plugging in headphones no longer disables built in speakers.

Hello.

When I plug headphones into the headphone jack, the builtin laptop speakers are not disabled. Sound plays through the laptop speakers as well as any speakers attached to the headphone port.

The intended operation is for the builtin laptop speakers to be disabled when headphones are plugged in.

This worked in 10.04 for sure, and I believe it did for 10.10 at release as well.
