 I'd like to have 3 streams being mixed by PulseAudio, going to the same
 underlying ALSA device, with each stream having its own volume.

   music beeps  speech  (PulseAudio devices)
     \     |     /
      \    |    /
       +---+---+
           |
        hw:0,0

 Also useful would be to obtain the "hw:0,0".monitor input stream, to be
 able to record all audio being played, for screencasting/teaching
 sessions.

 In my case, right now it means that turning up the music also turns up the
 desktop sound effects, annoying my office mates (they don't mind the
 music).  I also use a speech synthesizer to announce things.
