Detecting audio CD insertion?

I'm trying to write a script/daemon that will run when an audio CD is inserted. It would rip the audio with cdparanoia, tag and name the files according to CDDB data, then encode and store them. That's all pretty straightforward. The hard part is getting it to trigger when the CD is inserted. Stuff like submount or supermount doesn't work because audio CDs can't be mounted.

I've searched around a bit, but I haven't a clue where to start. Any ideas? Has this already been done? Or am I going to have to do my own kernel hacking?

Nobody told you about HAL?

Yeah man, hal is what you're looking for. You should check out gnome-volume-manager, it's a cool little screen. The ebuilds can be gotten from breakmygentoo.net. To get both them and the hal/d-bus ebuilds, use the overlay rsync instructions here.

Thanks, Roguelazer. It's hard to keep up with all the details of people working on Linux and its thousands of related projects when my job forces me to be very familiar with the Windows API and kernel. It's a lot to take in and remember

So I usually only play with the stable stuff that's in the official Gentoo portage, unless I have a reason not to.

I should have mentioned that this is a box without a display (or direct input for that matter), so no X, GTK, or Gnome. That's why detecting insertion is so critical.

hal and dbus don't require gnome or any of that. But gnome-volume-manager is a convienient interface to them, that's all.

You should look into ivman. It does the same things as gnome-volume-manager, but doesn't depend on gnome, gtk, X11, or any of that stuff.

You don't even need a script for this

Get ivman and set "abcde whatever" as "cdplay_cmd".

In ivman_ng it'll be possible to do this loads niftier (like, not starting to rip but playback when the cd has already been ripped and stuff like that). But that's very work-in-progress. More info in the wiki and on the mailing list.
