This is true; the headphone jacks usually have an integrated
disconnect switch for the internal laptop speakers, to be tripped
when a plug is inserted.
It's apparently no longer true, at least for newish Intel HDA
chipsets. Mine (SigmaTel STAC9872AK) would not switch off the internal
speakers when the jack was plugged in, so sound would come from both
the headphones and the speakers. A recent patch to the driver fixed
this.
So, which version of alsa-driver do you think can fixed this?
I have tried version 1.0.15-rc2, but that didn't work, I meant I even
can't use the headphones.
I use 1.0.14-rc3 now, which at least let my headphones work.
Sorry this doesn't help the OP any.
