As you command, so shall it be.  The (U.S.) Library of Congress, the
registration authority for ISO 639-2, spake thus:

#    The language code "und" is used "if the language associated with an
#   item cannot be determined" or "for works having textual content
#   consisting of arbitrary syllables, humming or other human-produced
#   sounds for which a language cannot be specified."--from MARC Code
#   List for Languages.

So in order for "und" to apply we must have a language, or at least
human-produced sounds of some sort.  C is out.  (The MARC list is the
direct ancestor of the ISO 639-2 list.)

No, it tells us that we have here language or paralanguage, but not
(to quote the MARC list again for the kinds of things to which language
codes are not applicable):

# instrumental or electronic music; sound recordings consisting of
# nonverbal sounds; audiovisual materials with no narration, printed titles,
# or subtitles; machine-readable data files consisting of machine languages
# or character codes.
