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. Regards, Clemens
