Most probably, you'll have to change the driver interface name to the one
you inscribed on your asoundrc file, instead of "hw:0", "hw:1" nor "hw:2",
which referr to each individual card device.

I'm only catching the topic this time, but I guess you had to do a special
asoundrc configuration to gang your three cards, hadn't you?
