I'm Quite new to this Ubuntu but recently started using it, 2 days back I had problem with muting the Laptop speaker when headphone jack is plugged, to resove this i searched and somehow tried with the Alsa mixer and got it perfect.

FYI this is the output of the Alsa script: [http://www.alsa-project.org/db/?f=9ec8099800aca2cb74ee35c2bf58125e45ca9f43][1]
