not an answer but just to tell you what running "groups" does, as
written in the man page:
Print group memberships for each USERNAME or, if no USERNAME is speciā
fied, for the current process (which may differ if the groups database
has changed).
So running "groups" as root reports the groups the user "root" is in,
not the groups you have on your system.
Try a "grep audio /etc/group", it will print something with a probably
of one minus epsilon.
