Yes, -novideo is a bit unreliable unfortunately...

I think -dumpstream and the first 10 MB or so would probably be enough
to show the issue.
In a single command (if it works):
mplayer -dumpstream -endpos 10mb dvd://2
output will be in stream.dump, and hopefully shows the same behaviour
as using the DVD directly (please check, and if not try larger sizes,
if it works you can also try to reduce the size, but make sure both the
initial "no audio" happens as well as the audio appearing later on when
playing it with mplayer).
