USB-Audio.conf defines all the surround devices because there are some
devices that actually use them. I could understand if "aplay -L" shows
all the default device names _including_ surround71.
I'm not sure how the device name list gets constructed; AFAICT the card-
specific .conf files are not supposed to define hints.

Clemens
