Hi, Debian 12, bookworm. I'm trying to get fluidsynth and pipewire playing together.
TL;DR everything seems to be running as it should, but I seem unable to get a beep from the MIDI keyboard. I carried over the config from a working 11/Bullseye installation. The aim is to get a USB MIDI keyboard (see below) making noises on the output loudspeaker. This is what pw-link says: | tomas@ariadne:~$ pw-link -vi | Midi-Bridge:Midi Through:(playback_0) Midi Through Port-0 | alsa:seq:default:client_14:playback_0 | Midi Through:Midi Through Port-0 | Midi-Bridge:iCON iCON iKeyboard 4 mini V1-04 at usb-0000:00:14-0-6- full speed:(playback_0) iCON iKeyboard 4 mini V1-04 MID | alsa:seq:default:client_16:playback_0 | iCON iKeyboard 4 mini V1-04:iCON iKeyboard 4 mini V1-04 MID | alsa_output.pci-0000_00_1f.3.analog-stereo.2:playback_FL | alsa:pcm:1:front:1:playback:playback_0 | ALC298 Analog:playback_FL | alsa_output.pci-0000_00_1f.3.analog-stereo.2:playback_FR | alsa:pcm:1:front:1:playback:playback_1 | ALC298 Analog:playback_FR The second entry is said keyboard: it seems pipewire "sees" it. Starting qsynth from the command line does: > qsynth > fluidsynth: error: failed to connect to the Jack server OK, there's no Jack server running. But pipewire-jack is installed. Wrapping it with pw-jack (as far as I understand this just sets some environment for the application to find the Jack emulation) seems to work: > pw-jack qsynth ...no error messages. Fluidsynth is started by systemd's user session: | tomas@ariadne:~$ cat .config/systemd/user/default.target.wants/fluidsynth.service | [Unit] | Description=FluidSynth Daemon | Documentation=man:fluidsynth(1) | After=sound.target | After=pipewire.service | | [Service] | # added automatically, for details please see | # https://en.opensuse.org/openSUSE:Security_Features#Systemd_hardening_effort | ProtectSystem=full | ProtectHome=read-only | ProtectHostname=true | ProtectKernelTunables=true | ProtectKernelModules=true | ProtectKernelLogs=true | ProtectControlGroups=true | # end of automatic additions | # required in order for the above sandboxing options to work on a user unit | PrivateUsers=yes | Type=notify | NotifyAccess=main | EnvironmentFile=/etc/default/fluidsynth | EnvironmentFile=-%h/.config/fluidsynth | ExecStart=/usr/bin/fluidsynth -is $OTHER_OPTS $SOUND_FONT | | [Install] | WantedBy=default.target (I took that over from the Bullseye instance and it references pipewire, so it seems the installer took care of fixing/updating things. Yay for the maintainers!). Still the whole thing is mute. On the old machine, hitting the keyboard's keys produced tones out of the loudspeaker. Now I guess I have to connect together some sources and sinks on fluidsynth, but I'm totally at a loss where to start, and I seem to be too stupid to find relevant docs. Help? Cheers & thanks -- tomás
