There isn't, and it's not easy to fix this in 0.10 for reasons of
backwards compatibility. You are free to register your own typefinders,
however, that detect things in whatever way you like (that may solve the
problem for m4a/etc., but doesn't solve it for the general case - it's
e.g. entirely possible to have matroska files with just audio).
