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):
--8<---------------cut here---------------start------------->8---
Loading soundfont: /usr/share/mscore3-3.2/sound/sf3/MuseScore_General.sf3
Loading soundfont: /home/giovanni/MuseScore3/SoundFonts/GeneralUser GS
v1.471.sf2
SoundFont(/home/giovanni/MuseScore3/SoundFonts/GeneralUser GS v1.471.sf2)
Sample(Grand Piano-D1) start(0) startloop(35640) endloop(70786) end(70787)
smaller than SoundFont 2.04 spec chapter 7.10 recommendation

musescore installed from Debian plays sounds using MuseScore_General.sf3

AFAIU the error
--8<---------------cut here---------------start------------->8---
Sample::decompressOggVorbis: open failed: Not a valid SNDFILE* pointer.
--8<---------------cut here---------------end--------------->8---

AFAIU this is not the case

I'll try to do it in the coming days
