LMMS 1.2.2 SF2 soundfonts no longer work in Wine 9.1.

These worked at least up to Wine 5.x series in Ubuntu 20.04 - but I installed
9.1 from the winehq PPA and the fonts no longer play. So this is a regression.

The program seems to work, other internal synthesizers work, but not the SF2
soundfont player.

Command line output ends:

03d8:err:winediag:MIDIMAP_drvOpen No software synthesizer midi port found, Midi
sound output probably won't work.

LMMS 1.2.2 is installed from the 64-bit Windows binary from
