I had the same problem with QSynth. But I cannot recall how/if I fixed
it (I've since given up using my old MacBook once Apple also gave up on
it in favor of a new Surface Laptop). But there may be a work-around.
If you run fluidsynth from the command line into shell mode (type
fluidsynth then return), load the soundfont (load filename; needs to be
the complete path to the sound font), you can then use a command to show
the current settings, that will include the port fluidsynth is using
(Help from the shell prompt should help you find it, I can't remember it
off the top of my head). Now confirm that FB is using a device with that
port number. That's the first thing. This gets a connection from FB to
fluidsynth. It should work this way without using QSynth.

Aloha.
I'm using FB 2.20.0 with Qsynth 0.5.6 with fluidsynth 2.0.5 on OSX 10.14.6
When I try to playback midi from a score within FB using Qsynth, Qsynth
shows the midi messages and the green-light blinks on and off
appropriately but I get no sound. I've loaded the
GeneralUser_GS_v1.471.sf2 soundfont and cannot find out what's wrong.
At one point this did work but the circumstances were odd. I was
similarly struggling to get it to work then, out of nowhere, there was
scratchy irregular playback that finally stabilized and worked well.
However, as I feared, when I tried to restart the setup, I was back to
the same deal: all looks ok but no sound. This points to something
about the soundfile but I don't know enough to further debug. Any
thoughts or pointers would be welcome.
When I play the same midi file with fluidsynth from the command-line
with the same soundfile it works fine and SimpleSynth and VLC work fine
so I know the computer audio is ok.
I've tried changing the audio setting from default to speakers but no
joy there either.
Mahalo.
