That's not entirely true. If you install alsa-plugins you can
configure alsa to default to the jack plugin. See the instructions at
http://alsa.opensrc.org/index.php/Jack_%28plugin%29 . This lets me
run prboom through JACK even though prboom is not JACK-aware: the
ALSA configuration silently reroutes prboom through JACK.
This isn't a surefire solution: it depends on your application
respecting the ALSA default. If the app *insists* on talking straight
to the hardware then you're stuck. Also some apps like mpg123
complain about samplerate issues that I haven't fixed. I'm assuming
that they *are* fixable, I just haven't got round to doing it.
