Use 'hw:Loopback' device or assign any other car ID string as the module 
parameters (id=<your_string>) or you may change the card ID string at
runtime using 'echo <your_string> > /sys/class/sound/card1/id', replace 
card1 with the loopback card index (this way may be used in udev scripts 
where you can check the module name (snd_aloop) as well).
