That includes media players (mpv/vlc/etc), web browsers (mozilla/chromium/electron/etc), and literally every app…Once qsynth/qjackctl/ardour is started, even when I’m not actually using them (I’ve got them open so I don’t forgot that I wanted to use them for something), no videos will play at all—they just get stuck on a single frame…How can I set things up so these fluidsynth UI apps aren’t breaking everything this way?
This sounds like a common problem when using JACK and PulseAudio
When JACK is started it usually takes control of an audio device away from PulseAudio
If a PulseAudio stream is trying to play to the output device (sink) that is no longer available, the media player/web browser would be unable to play
Audio Streams in PulseAudio must be re-routed to PulseAudio JACK Sink connection into JACK, then audio can be connected in JACK to play audio to system output to use the same audio device as before
Please post response to this command when JACK is running to show PulseAudio information
pactl list sinks short && pacmd dump
Commands based on that data can be added to QjackCtl to ensure audio can play through JACK without being choked
Some of the commands need a card name specific to your hardware

### EOF
Which commands? And do I add them prior to launch ( qjackctl --don't-hog-speakers-devices-flag | qsynth --prevent-jack-from-hogging-devices-flag), in some text field in qsynth’s or qjackctls GUI, in some config file (I’m guessing is qjackctlrc since Qsynth had a qsynthrcfile), or any combination of those three?
The PulseAudio data for both before and after JACK is running is not showing an expected change
When JACK is started PulseAudio module module-jackdbus-detect should create an audio connection Pulseaudio JACK Sink for audio to play via JACK
The connection should be shown as a PulseAudio sink like this:
7 jack_out module-jack-sink.c float32le 2ch 48000Hz IDLE
I suggest you add the Pulseaudio JACK Sink connection with this command
pactl load-module module-jack-sink channels=2
and use this command to set it as the default-sink for audio playback
pactl set-default-sink jack_out
Audio should now be able to play from PulseAudio through JACK to the output device
(which I assume is the Onboard Audio SPDIF digital output iec958-stereo )
But audio playback may still be choked if the audio stream was assigned manually to use either the iec958-stereo sink taken for JACK use or the Simultaneous Output combined sink
You may need to manually change some audio stream manually in PulseAudio controls to use PulseAudio Jack Sink connection
If that works then QjackCtl can be reconfigured to load and unload PulseAudio connections automatically
Oh, the SPDIF digital output is from my 2011 Creative sound card. For some reason every speaker I have can’t receive sound from any analog port except for the one built into the motherboard (which uses the duller-sounding intel audio driver), So I bought the cheapest digital-to-analog converter on Amazon to use the sound card’s SPDIF outputs instead. The hdmi output is thanks to my connecting a monitor with speakers built-in using a hdmi-dp adapter cable to connect it to my old graphics card. I use that output only for audio playing on that screen (because it costs too much cortisone release to see human mouths moving but the sounds they’re making aren’t coming from the same direction)…I don’t know if that makes a difference to any of these pactl commands or not…does it?
I was trying to deal with the original problem of playback through JACK before other possible issues with PulseAudio
But any problem with ALSA hardware devices should be investigated before a software issue
Please post response to
sudo alsa-info.sh --upload
sudo: alsa-info/sh: command not found
bash: : command not found
pactl load-module module-jack-sink channels=2
Failure: Module initialization failed
(Sorry, for got to add this)
there was a typo in the ALSA command it should have been sudo alsa-info.sh --upload
Was JACK running when you tried to add module-jack-sink ? PulseAudio can only add a connection when JACK is active
If JACK was active and the command failed I suggest you check the contents of QjackCtl Messages log for any errors
No, jack was not active at the time. I thought I had to do that before, like insmod/modprobe commands. I got qjackctl up and running and now it seems to work…
Actually, I just discovered that Virtual MIDI Piano Keyboard takes Midi and Custom Soundfont input, and that was all I needed for this project…
