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"
