  You probably want to investigate the use of jack audio connection kit.
  The connections listed by aconnect are MIDI only.
  The output of fluidsynth will be audio data (like .wav).
  jackd can be used to connect or patch audio among compatible applications.
  Jackd has a GUI front-end called qjackctl which is quite useful.
  You should also modify /etc/security/limits.conf to enable real time priority
  for the user or audio group which is running fluidsynth and jackd and any 
other
  audio apps.

  I'm not sure if you are running the GUI apps qjackctl and qsynth, or only the 
CLI programs.
  Also, your results may vary depending on which distribution of Linux that you 
have
