Fix: Use FluidSynth default soundfont #8953

merged 1 commit into from Apr 7, 2021

@ghisvail ghisvail commented Apr 5, 2021

Motivation / Problem

FluidSynth provides a build option to set a default soundfont which may be overridden by Linux distributions such as Debian to support alternative soundfont providers (such as Fluid, OPL-3, MuseScore, ...). This PR enables OpenTTD to use this default soundfont if present, which is arguably more flexible than maintaining the hard-coded list in the OpenTTD code base.

As an immediate benefit of this, the Flatpak build of OpenTTD will no longer require patching the hard-coded list. Instead, only FluidSynth needs to be configured with an appropriate default soundfont in place inside the runtime.


The implementation now loads the default soundfont configured with FluidSynth, if any. The previous find-first lookup from the hard-coded soundfont list is still used as a fallback if no suitable default soundfont is found.

Worth backporting for future Flatpak updates. I already use this patch for v1.11.0 but would be great if I could drop it for v1.11.1 onwards.
