Hi,

I'm having problems running Fluidsynth as a service

fluidsynth --version
FluidSynth runtime version 2.3.1
FluidSynth executable version 2.3.1
Sample type=double

If I run Fluidsynth as a service, this is what gets written to the systemd log:

systemctl status fluidsynth

This looks like errors from Pulse Audio (/tmp/pulse-...). So maybe your Fluidsynth is not being started with the right options/configuration.

You didn't post your systemd service file, but you've prevented it from writing to /tmp, which appears to be the issue. You could use PrivateTmp=true to allow it to write to its own /tmp.
