I don't have that file on my system.  What package did it come from? 
(According to man adduser the relevant file is "/etc/adduser.conf".)

If you've already created the user bob (for example) and want to add group
audio to his account:

# adduser bob audio

According to man adduser:
"adduser [options] user group"
and
"If called with two non-option arguments, adduser will add an existing user
to an existing group."
