speakers & headphones- only together or any

I recently bought notebook with vista home edition, it has realtek HD,

problem is loudspeakers are still on when i plug in headphones its

annoying and i don't know how to change it, i tried to mute, well

stricte i didnt have to because rear output was muted since begining,

but it doesnt help, muting front mute both - speakers and headphones,

disabling speakers got influence on headphones, they act like they are

one, and nothing cant split them out, i tried most options and nothing

works. But its notebook and headphones not couple in true love lol. I

would be appreciated for any precisional advices.
