'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.
