Of course, Lennart's first quoted comment talked about this. Apparently
the sound cards can tell you whether something is plugged into a given
jack ('jack sensing') but ALSA doesn't export this information anywhere
and only reads it for a couple of cards... *sigh*

Speaking of this, I was quite impressed by the Vista Realtek driver package for my new X58 motherboard.

It uses jack sensing and whenever something is plugged in, it pops up a dialog window *with a connector diagram* and asks you what you just plugged in. Then it lets you test it and set levels.

It's very useful.

That's not true any more - there is now a standard interface for reporting jack status to user space with a helper in kernel for the drivers and support is being added to drivers to use it - 2.6.29 has some that should cover a lot of common laptops.

Note that not all sound devices are going to be able to do jack detection - it does require hardware support and simpler devices will often not have that support.
