I have Linux Mint 20.3 on a laptop HP EliteBook 840 G7.
I have installed Ardour 7.1.0 (rev 7.1) in Flatpak.
I am able to play midi tracks using the Reasonable Synth.
However, if I use the Fluid Synth I have no output sound…
I have tried several SoundFonts, with no result: if I hit the keyboard on the edge of the track editor (or when the head crosses notes in the editor chart) the yellow meter moves, but no stereo green meters.
I have the same routing grid than in the Reasonable case…
What could be wrong?
I would be happy to provide screenshots and any other info.
I have installed the demo version, but the problem persists.
I noticed that in the demo version, together with reasonable synth and fluid synth, I also got General midi synth… which is missing in the version I got via flatpak…
In the demo version both general and reasonable work, and fluid doesn’t.
I have solved it!
Actually, the suggestion from @Piergi, although didn’t work per se, has lead to the solution: I have launched the demo from the terminal, so I have been able to read the error messages. It turns out that I was using the wrong format of soundfonts, so that FluidSynth was not loading them. Reading the error message led me to understand the situation!
