 Replying to [comment:17 bonefish]:
 > If you listen to music and another application (chat for instance) plays
 a notification sound, some component has to mix the two. And that's the
 mixer's job. I suspect that there are workflows where audio people use
 more than one sound generating application at a time. Again, the mixer's

     Well usually in a audio application the sound gerneration is handled
 in the hosting or mixing program itself. IE the program write all the
 rendering to the master output and typicaloly handles all associated sound
 that need mixing as well.

    I hadn't thought about beeps and buzzers for notifications. typically I
 turn those things off. Good reminder !

 > Good that all of this is possible already. If an application just wants
 to control the hardware node's parameters, it can use the respective
 parameter web -- that's exactly what the media preferences application is
 doing. If the application wants full control over the output, it can
 disconnect the mixer and directly connect to the hardware's node (this
 would, of course, shut up all other applications). So I don't see a show
 stopper for whatever kind of audio application you have in mind.

   It good to know. I am looking at trying to build a application around
 the bepia for haiku but built of the ideas and code of other DAW's. Lots
 to learn here. Just wanted to make sure that whatever fix got implement
 for this issue, did not block those applications later requireing a
 massive amount of work to unfix it.
