[PD] RPI USB Audio -nogui "Invalid value for card"

[Miller Puckette]

You can type "pd -nogui -audiodev 1" (1 is the default anyway) to get
the "hardware" device or  "pd -nogui -audiodev 2" to get the "plughw"
device.  The "device numbers" in the Pd argument agree with the numbering
that "-listdev" prints out.

cheers
Miller
