which is a bind on my laptop as most of the time I have it set to the headphones socket, and it doesn't switch to the internal speakers if I unplug it. I think ALSA used to do that automatically.
No, ALSA does not do this, pulse does. So when jack takes the device, pulse no longer deals with it. Most newer systems can be switched by changing levels in ALSA. Some systems have pin switching that needs to be done (as root) and yet other systems do the switching physically in the plug. headphone plugin/out are not hard to detect, but knowing what to do is system dependent even with alsa, while most systems use the "headphone" label, it is a tossup if the speakers are "Speakers", "Front" or something else.
