Strange bug in .asoundrc ??

[Dominique Larchey-Wendling <Dominique.Larchey-Wendling@loria.fr>]

Dear all,

It seems that neither the current ctl.hw function nor the following
simplified function ctl.!hw work correctly when the argument CARD is
given to the function. It works however when no argument is given as the
following test examples show it. It have alsa-lib version
1.0.14-0.4.rc3.fc7 installed on FC7.

Is this a know bug of alsa-lib ? It is strange because this bug does not
   show up with pcm.hw for example.

--- .asoundrc ------------------------

ctl.!hw {
	@args [ CARD ]
	@args.CARD {
		type string
		default "0"
	}
	type hw
	card $CARD
}

ctl.rha  "hw"
ctl.tata "hw:0"
ctl.toto "hw:1"
