Hi Antonio!

As of Natty, Headphones are only supposed to mute internal speakers, not line-outs. However, upstream is working on to make this behavior configurable, so I assume it will be possible in the next version of Ubuntu, and likely earlier through upgrading alsa (which is not yet available for Natty).

[Antonio Vázquez Blanco (antoniovazquezblanco)]

The thing is that even through alsa mixer this is not possible... I think that every output should have a mixer channel but headphones or front line out as you want to call it, isn't modificable. Thanks for your fast reply.
