that's what I always thought, too, that it was like the old-fashioned
stereo where there was a mechanical switch in the headphone jack that
broke the circuit to the speakers.
but that's not the way modern laptop audio works. or if it is, then
I'm totally confused. why? 'cause on my eeepc 901 I had the same
problem, i.e. plug in the phones (or external speakers) and the internal
speakers continue to "speak".
Not until I found the right incantation for the config file this thread
speaks of did the speakers shut off when something was plugged into the
headphone/line-out jack.
Now if that's not under software control, I don't know how else you
would describe it.
