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.
