kmid2 help

[Petrus de Calguarium]

I have installed both fluidynth and timidity++. I set kmid2 to start timidity at 
start-up and have a midi mapper file selected. I left the default settings in kmid2 
for timidity alone (I do not know whether a sound font will be automatically loaded, 
nor do I know how to load one in timidity).

When I select a midi file to play, the progress indicator suggests that the file is 
indeed playing, but there is no sound.

I have checked kmix and all the available volume sliders are up (I checked if other 
ones were available, but I don't think any of the ones not shown would be needed or 
have any use).

Any ideas?

I have no idea how timidity or fluidsynth work. In the past, I used to expressly 
install an old SoundBlaster Live card with built-in midi for the purpose, but, 
according to the kmid2 documentation, soft-synths such as timidity and fluidsynth 
should be sufficient.
