Much nicer! The last nit is that "multimedia0_codec" is now sorted
incorrectly. It starts with "m" so it shouldn't come after "s". Yes, I
know that this rule means that these two things are no longer next to
each other, but that's the rule we have right now.

If it's important for you for them to sort together, I suppose you
could change the label to "sound_multimedia0_codec" though that's a
bit of a mouthful. I'll leave it up to you whether to rename (and keep
the current ordering) or keep the name (and move the node).
