I'd guess this is just an issue of an inappropriate port (was it
"connector" in gnome-volume-control jargon?) being in use. Selecting a
headphone port will probably enable the correct output and mute the
internal speakers. You mentioned your "real speakers", so you probably
don't use headphones, so the port name is misleading, but aren't your
real speakers connected to the same connector as you would use if you
used headphones?
