musescore does not play sounds (Not a valid SNDFILE* pointer) |

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'

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!
