hey miller.

yeah on raspbian i got rid of the "invalid card" nag. no way to test
stuff at moment via gui. all done via ssh on headless rpi.

my guess is it has nothing to do with pd. usb cards have to be set to default.

$ nano /etc/asound.conf

pcm.!default {
        type hw
        card 0
}

ctl.!default {
        type hw
        card 0
}

$nano /etc/modprobe.d/alsa-base.conf
change line:
# Keep snd-usb-audio from beeing loaded as first soundcard
options snd-usb-audio index=-2

to:
# Keep snd-usb-audio from beeing loaded as first soundcard
options snd-usb-audio index=0
