There may or may not be a better way to do this, but go ahead and use
dumpstream until mplayer has dumped at least as far as you need. Then,
experiment with:
$ dd if=stream.dump bs=1M skip=xxx | mplayer -
until you find the right skip offsets for the beginning and end. Use the
start value for skip= and subtract them to get count=, so then you have
something like:
$ dd if=stream.dump bs=1M skip=123 count=45 of=cut.dump

Note that depending on your cut positions, sometimes the audio may not
play correctly, or mplayer will select a different track. That's normal,
and you can vary them slightly until they work.
