[LAU] Q: does jackd mix?

[Julien Claassen]

A guess of mine, yet built on some logic: It mixes the streams, before sending 
them to one port.
   Why? If it would send unmixed streams to ALSA, ALSA would need to mix them, 
which it doesn't do automatically. I'm not sure about OSS's and freebob's and 
the other backend's features.
   Why else? JACK also sends (possibly multiple) streams not only to the 
soundcard but to other applications. If JACK wouldn't mix them, then your 
applicationmust have special code to deal with it.
   Kindest regards
           Julien
