PA is able to incorporate the boost into the general mixer pipeline giving you just a simple volume control overall. Please provide the output of "pacmd ls" and "amixer -c0" so I can help debug what is going on. Ultimately, I suspect it's just a matter of picking the right "port" for your input via pavucontrol or gnome-volume-control.
