No Pulseaudio JACK Sink

It seems that I used to have a Pulseaudio JACK Sink option to capture audio straight from pulse. I doesn't seem to exist anymore and I can't sort out why.

As an example I captured an mp3 using:

ffmpeg -f jack -ac 2 -i ffmpegpulsein test.mp3

The xml for ffmpegpulsein's patch was:

<!DOCTYPE patchbay>
<patchbay version="0.3.10" name="ffmpegpulsein">
 <output-sockets>
  <socket exclusive="off" client="PulseAudio JACK Sink" type="jack-audio" name="PulseAudio JACK Sink">
   <plug>front-left</plug>
   <plug>front-right</plug>
  </socket>
 </output-sockets>
 <input-sockets>
  <socket exclusive="off" client="ffmpegpulsein" type="jack-audio" name="ffmpegpulsein">
   <plug>input_1</plug>
   <plug>input_2</plug>
  </socket>
 </input-sockets>
 <slots/>
 <cables>
  <cable output="PulseAudio JACK Sink" input="ffmpegpulsein" type="jack-audio"/>
 </cables>
</patchbay>

I no longer have a device to output audio to of this name. How does one capture computer audio output through JACK?

Re: No Pulseaudio JACK Sink

module-jack-sink and -source have been replaced with module-jackdbus-detect in default pulseaudio configuration.
module-jackdbus-detect only works with jack's dbus interface introduced in jack2, not with legacy jackd.

You should be able to still use the old -sink and -source, but you need to set them up yourself in your pulse config.

If you have everything set up correctly, I think you still need to connect pulseaudio output to recording input with jack to record anything.
