Hi Mark,

By coincidence I've been working on adding the extension required - the 
loopback device - to JOAL (jogamp.org's JOAL) and just joined this list 
last week to ask some questions about this very functionality.

The loopback device only works with openal-soft, but lets you render the 
mixed output to buffers.  Check the archives for this month for some 
details: i'm sure you wont have trouble finding it.

I've been side-tracked with other hacking, and not really having much 
fun with jogamp's funky build/run-time system, so I haven't spent a lot 
of time on it.  I have it working - it's just 3 api calls - i'm just 
cleaning it up for submission.  But i'm busy with other stuff this week.

  Michael
