Hi Doug,
As for the jack. I do not want to be a party pooper. My take on jack is that there are many degrees of freedom in Linux audio stack(s) and it can be very difficult to find problems by adding even more degrees. I use jack daily in my studio so I think it is good and very nice. But in the end, it's up to you to choose.
But lets just check if your fluidsynth (the software synth used in Qsynth) is up to par with your current setup (pulseaudio)
As I said. First install a soundfont. Ex.
zypper in fluid-soundfont-gm
Grab a midi-file that you have or download some. Ex.
wget https://www.mutopiaproject.org/ftp/BeethovenLv/WoO59/fur-elise-guitar-duo/fu... -O ~/Downloads/fur-elise-guitar-duo.mid
then run fluidsynth from the command line to see if you got any sound:
fluidsynth -a pulseaudio /usr/share/sounds/sf2/FluidR3_GM.sf2 ~/Downloads/fur-elise-guitar-duo.mid
stop it on the fluidsynth cli by issue command quit
Thank you for your input. It has problems on my system: linux1:~ # zypper in fluid-soundfont-gm long paragraph of complaints, ending in "nothing to do"
