Jack with PA bridge: Pulseaudio does not work, Jack has no sound

I installed jack2, cadence, and pulseaudio-jack - trying to do this https://wiki.archlinux.org/index.php/Pu … dio_method
I also added myself to the realtime and audio groups.
Cadence, Catia, and pavucontrol: https://i.imgur.com/YdEmJYg.png

$ mpv --ao=jack Better\ Be\ Quiet\ Now.mp3
[ffmpeg/demuxer] mp3: Estimating duration from bitrate, this may be inaccurate
 (+) Audio --aid=1 (mp3 2ch 44100Hz)
AO: [jack] 48000Hz stereo 2ch floatp
A: 00:00:00 / 00:03:35 (0%)


Exiting... (Quit)


$ mpv --ao=pulse Better\ Be\ Quiet\ Now.mp3
[ffmpeg/demuxer] mp3: Estimating duration from bitrate, this may be inaccurate
 (+) Audio --aid=1 (mp3 2ch 44100Hz)
[ao/pulse] The stream is suspended. Bailing out.
[ao] Failed to initialize audio driver 'pulse'
Could not open/initialize audio device -> no sound.
Audio: no audio


Exiting... (Errors when loading file)

$ cat /proc/asound/card1/pcm0p/sub0/hw_params
access: MMAP_INTERLEAVED
format: S32_LE
subformat: STD
channels: 2
rate: 48000 (48000/1)
period_size: 1024
buffer_size: 2048

Edit: I think it was just solved by force-restarting in Cadence!

It is not solved after all.
Jack works fine, but not PA.
mpv with --ao=pulse does not yield an error anymore but does not output any sound.
Meanwhile, the only output device in pavucontrol is "Dummy output".

Re: Jack with PA bridge: Pulseaudio does not work, Jack has no sound

Can you post terminal output of cadence (and/or an updated screenshot of the current situation)? Or wherever the general log of starting jack should go? And maybe as well as

sudo fuser -v /dev/snd/*
pacmd list-modules
pacmd list-sinks
pacmd list-sink-inputs #While having mpv running in pulse mode

Maybe also read through this thread for some potential pointers: https://bbs.archlinux.org/viewtopic.php?id=255564

FWIW from what i'm understanding of jack, the config in your screenshot looks more or less correct.
