please configure your system to start and run "jack" properly!
or else, set qsynth to use "alsa" or "pulseaudio" instead (cf. Setup > Audio > Audio Driver: ...)

or else, set qsynth to use "alsa" or "pulseaudio" instead (cf. Setup > Audio > Audio Driver: ...)

I selected pulseaudio there,but I still get this error and it doesn't play sound if I test it in a game.
Do I have to change another setting?

[ghost]

Do I have to change the midi driver?
Cause I only changed it to pulseaudio in the "audio" tab,but it the "MIDI" tab I have jack set as audio driver.
The problem is that I can't change it to pulseaudio,if I click on it,it only shows "alsa_raw","alsa_swq","jack" and "oss",what do I have to set?

[rncbc]

i believe you'll be fine with:
Audio Driver: alsa
MIDI Driver: alsa_seq
cheers

[ghost]

Thanks,it works.

[ghost]

So I tried the same game I tried yesterday,but I didn't hear midi music.
I didn't change settings in qsynth or another soundfont.
I know that it normally works on this game,cause I tried that yesterday.
I played around in the sound settings of the game,so could it be that I have to set something in the games audio options,so it works?

[ghost]

Btw I don't get that error,I only don't hear music in game.

In Pavucontrol it looks like this (the thing at the bottom is the game that uses midi):

I use Manjaro Kde and Kernel 5.9 and my soundcard is the one that's build into the Asrock x370 Pro 4.
I have the newest stable versions of Qsynth and Fluidsynth installed from the official Manjaro Repository.
Is there any other info that I should provide?
