How to disable sound when earphone not plugged in ?

[mbee]

Hi,

At my job, it's really annoying that my silent looking laptop becomes suddenly LOUD when my audio jack loosen.

Is there a way to automatically mute all sounds if no earphone is plugged in ?
It would also be helpful if that setting could be modified back on, when I wanna watch movies, etc.

Thanks

Hi,
I was intrigued as to whether this was possible myself so had a quick 'look see' via Google and despite one or two promising links it seems this cannot be easily done. If I do come across something that may help I'll post (unless other forum users have an idea).
