Hello,

I'm using Guix on top of Debian 10, this version:

Toggle snippet (9 lines)

Generation 123 lug 26 2021 18:28:56 (current)

commit: 151c54609b74f27f6954768d72fdb67525b1f784

If I run musescore from the command line, I get a lot of messages

(removed repeating lines with OMISSIS):

Toggle snippet (27 lines)

So it seems that musescore is loading SoundFonts without an error but

later it fails opening them with "Sample::decompressOggVorbis: open

failed: Not a valid SNDFILE* pointer."

If I try to export I get this error on stdout:

Toggle snippet (9 lines)

Fluid:loadSoundFonts: already loaded

MasterSynthesizer::setState: unknown <>

open soundfile failed: File contains data in an unimplemented format.

Could not write to device

QMutex: destroying locked mutex

It seems a bug with the soudfile (soundfont?).

Thanks! Gio'

For the record, which SoundFont are you using here? Last time I

checked, the one that was bundled with MuseScore itself ought to work,

but perhaps you need a little configuration magic to make it find that.

Ah, yes, I recall not being able to load that font with FluidSynth as

well. Back then I thought it was an error in FluidSynth, but it does

appear to be an issue with the SoundFont then if not even MuseScore

loads it.

If so, then it's two different libraries, as MuseScore doesn't use

FluidSynth for MIDI synthesis – it's more likely that the font is

simply broken.

It would be nice to investigate when that font first broke or if it

ever worked. My personal hypothesis is that a font was a requirement

for building it, but that users used different fonts in practice and

thus never noticed.

Please are you reproducing the same error?

I tried installing musescore3 (v. 3.2.3) from Debian stable and AFAIU

that SoundFont is loaded (with a lot of warnings):

AFAIU this is not the case

Ah, but that's Debian's MuseScore_General.sf3. Those two could be

different for all we know. Did you binary diff them or did you try

using the SoundFont from the Guix installation with Debian's MuseScore?

Good point, it might be that libsndfile was compiled without Vorbis

support. However, there is also a nonzero chance that Fluidsynth or

Musescore use libsndfile incorrectly, for instance w.r.t. Vorbis

support [1]. Aside from the broken file hypothesis, that is...

musescore is now at 4.0.2, and I gave it a try and it can play sounds

fine.

Closing, let us know if you still are having issues!
