You have removed the code that initialize the audiohook, that is correct,
but you also need to avoid creating a datastore on that channel if you are
reading the value. Just reply with a ast_copy_string(buf, "0", len);

If you allocate a datastore, then the next call to valume_write won't
create the audiohook.
