bug#49753: musescore does not play sounds (Not a valid SNDFILE* pointer)

[Giovanni Biscuolo]

Hello,

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

--8<---------------cut here---------------start------------->8---

Generation 123  lug 26 2021 18:28:56    (current)
  guix 151c546
    repository URL: https://git.savannah.gnu.org/git/guix.git
    branch: master
    commit: 151c54609b74f27f6954768d72fdb67525b1f784

--8<---------------cut here---------------end--------------->8---

If I run musescore from the command line, I get a lot of messages
(removed repeating lines with OMISSIS):

--8<---------------cut here---------------start------------->8---

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:

--8<---------------cut here---------------start------------->8---

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

--8<---------------cut here---------------end--------------->8---

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

Thanks! Gio'
