[SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

I installed jack2, pulseaudio-jack, cadence.

When I start cadence, the ALSA -> PulseAudio -> Jack bridge is automatically enabled, which is what I want.
I had to add myself to both the `realtime` and `audio`groups. After that, I managed to play a song on spotify. That is, the progress bar moves to the right, but the sound is just really choppy and unrecognizable. Besides, the Xruns counter in cadence goes up rapidly.  However DSP Load is consistently around 0.5%.

watching this video (https://www.youtube.com/watch?v=Nx9snvfzRFY) I tried to add this to `/etc/security/limits.conf`:

@audio - rtprio 99
@audio - memlock unlimited
@audio - nice -19

After which there is no sound when I run jack, and spotify says it can't even play any sound. I guess I should revert that.
pavucontrol looks like this https://i.imgur.com/p9ysK3b.png (I have tried to leave the top-most device both muted and unmuted), and both devices are completely silent.
At some several points during all my attempts, there was only a "Dummy output" here, but a reboot would 'fix' that.
Invariant through all these different runs, Xruns keeps going up, whether there is any sound or not.

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

It looks like in Cadence your Device/Interface (greyed out by the look of it) is an analog device and I'm guessing that that's probably why you're getting loads of xruns since the CPU can't process the analog.
From ALSA alone, without JACK and Pulseaudio, what is your default sound card?
Do you get the same quality audio when you run speaker-test -c 2?

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

In cadence, "Device/Interface" is greyed out when "Duplex mode" is checked, and then you have to select Input and Output device so I think you can ignore that field.

$    cat /proc/asound/cards
 0 [Snowball       ]: USB-Audio - Blue Snowball

 2 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xfe800000 irq 51

I'm pretty sure 2 is the one I'm using then. It's the one I should use for output.
What's the problem with an analog device? I tried to change it to the Digital entry in the dropdown list but then Jack fails to start. Logs:

Yes and now I hear clearer what is actually happening. It sounds like it's rapidly altering between volume 100% and volume 0% (perhaps at 10 Hz).

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

Was ALSA is working properly before you installed Pulse and JACK?
What is the output of

aplay -lL
speaker-test -c 2
amixer
pacmd list-cards
pacmd list-sinks

with both JACK and Pulse disabled?
Also delete whatever asoundrc you have configured in your home directory. (You can save it somewhere if you wish).

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

I have not been using ALSA alone, only ALSA + Pulseaudio, and this setup worked fine, and still works fine now after I rebooted.
Do you still want me to try with ALSA alone? Haven't been able to turn off Pulseaudio. `.pulse/client.conf` has `autospawn = no`, but after I run `pulseaudio --kill`, it does autospawn (I can see that in e.g. pavucontrol - it briefly waits for connection then it's back to normal.

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

It's good idea to see what output you get with speaker test using ALSA alone just to make sure your ALSA is using the default  card you intend to use, and that the sound is OK.
You should be able to kill pulse and restart as you wish. Try killall pulseaudio. You might need to find out what's spawning it automatically.

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

(why the last two if pulseaudio is off?)

No those commands don't work without pulse.
But it is clear your ALSA is not working properly:

ALSA lib pcm_dmix.c:1089:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2,No such file or directory

Try to get a clear output from ALSA first before adding pulse and JACK. The speaker test should work cleanly on ALSA alone.
Try a different card:

speaker-test -D default:PCH -c 8
aplay -L | grep :CARD

And have a look at the ALSA wiki.

EDIT: Do you have an asoundrc? It's either in /etc/asoundrc or ~/.asoundrc. Temporarily delete them (copy somewhere safe) while testing ALSA.

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

Alright, I had deleted .asoundrc, but now I deleted /etc/asound.conf.

$ aplay -L | grep :CARD
hdmi:CARD=HDMI,DEV=0
hdmi:CARD=HDMI,DEV=1
hdmi:CARD=HDMI,DEV=2
hdmi:CARD=HDMI,DEV=3
hdmi:CARD=HDMI,DEV=4
hdmi:CARD=HDMI,DEV=5
usbstream:CARD=HDMI

surround40:CARD=Generic,DEV=0
surround41:CARD=Generic,DEV=0
surround50:CARD=Generic,DEV=0
surround51:CARD=Generic,DEV=0
surround71:CARD=Generic,DEV=0
iec958:CARD=Generic,DEV=0
usbstream:CARD=Generic
usbstream:CARD=Snowball

So I tried

$ speaker-test -c 2 -D default:Generic

Which worked!

From `aplay -l` it seems like Generic is card number 1. Why does aplay -L say "default:CARD=Generic" though? If it was default why would I have to specify it on speaker-test?
How can I find which card ALSA uses now (which does not work)?

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

The default card with the pulseaudio-alsa config tries to invoke a pulse server.  but reads weird that it tries to invoke a dmix. FWIW, what is your end goal here? The mentioned applications so far don't really benefit from jack and you are introducing a lot of complexity for potentially little gain. Generic is also often a strange default codec to have what do you get for

sudo fuser -v /dev/snd/*
systool -vm snd_hda_intel #Needs sysfsutils

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

I'm installing JACK so that I can use Ardour and produce sounds and music. I want it to play well with other apps like Firefox, Spotify and Discord, so that's what I'm testing first, and that's why I need Pulseaudio as well.

I tried to follow this and then reboot, but it had no effect.

options snd_usb_audio index=1
~  $ cat /proc/asound/modules
 0 snd_hda_intel
 1 snd_hda_intel

`snd_usb_audio` was in the second output at index 0 previously and now it's gone. Blue snowball is gone from `aplay -l`. I guess I'll revert what I did here.

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

I'm installing JACK so that I can use Ardour and produce sounds and music.

In that case it's probably best to concentrate in having ALSA and JACK working together first then adding Pulse later.
I won't worry about your snowball for now. It's important you get ALSA right with the correct sound card. When your JACK is setup properly later on, it will be easy to add devices, including the snowball.
Now that snd_hda_intel is set to index 0, that should be the default card. What is the output of the simple speaker test?
I have no idea how to read the systool output V1del suggested by the way.

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

If you want to ensure the index loading order specify all indices explicitly, or rather define negative indices so that the devices you don't want at first position get a later position for example

#This shifts the analog card to position 0 and the HDMI card to 1
options snd_hda_intel index=1,0 
#This tells the snd_usb_audio to take whatever index up to 2 -(index+1) but if 2 isn't free it's also free to take position 3 
options snd_usb_audio index=-3 

but all of that is just skirting around the underlying issue. If you now start jack, therefore without the pulseaudio bridge/support, do you still get warnings/xruns? For the realtime permissions to be properly set up it should probably be sufficient to install the realtime-privileges package (and rebooting/relogging at the least)

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

Thanks! Your modprobe conf made it selectc the right default card!

Now in Cadence, I selected "ALSA -> JACK (Plugin)" bridge and started Jack - it seems successful and after 10 minutes (with some playback from e.g. Firefox) there are only 2 Xruns.

I was also able to run Ardour. So I suppose that ALSA + JACK is now just fine, thanks!

Next, I try to add pulseaudio.

I copied back my /etc/asound.conf which I think makes it work with pulseaudio:

pcm.!default {
  type pulse
  fallback "sysdefault"
  hint {
    show on
    description "Default ALSA Output (currently PulseAudio Sound Server)"
  }
}

ctl.!default {
  type pulse
  fallback "sysdefault"
}

I noticed that (probably cadence) generated a new ~/.asoundrc that seems specific to JACK, so I use my old ~/.asoundrc from when I had ALSA + Pulseaudio:

pcm.!default {
    type plug
    slave { pcm "pulse" }
}

pcm.pulse {
    type pulse
}

ctl.mixer0 {
    type hw
    card 0
}

ALSA + Pulseaudio thus works together now (at some point it didn't, before I copied back the old asound.conf and .asoundrc). And when I try to start JACK through Cadence with the pulseaudio bridge, then it all seems fine: no Xruns, and I can see volume bars moving in pavucontrol. However, I don't hear any sound.

Two screenshots showing pavucontrol: https://imgur.com/a/jzUFwC5 (while a video plays in firefox in the background).

Then, under the Playback tab, I tried to change the output device(?) of Firefox from "Jack sink ..." to "Family 17h ..." which is what normally outputs sound I think. But then Firefox cannot output sound anymore (video stops playing).
I'm not sure how I'm supposed to do this.

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

It's the Family Output Device. Again that's the analog one. Pulse is not finding the right output device,

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

Is it really wrong? Because when using ALSA+Pulseaudio, the analog Family output device is used: https://i.imgur.com/xtyIRy6.png
And this works well, I hear sound.

Well if it works well and your happy with your device, then your problem is solved.

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

@d_fajardo the problem isn't solved as the pulseaudio -> jack bridge doesn't seem to work yet.

Double check in cadence that the pulse sink that's connecting to your jack daemon is being routed to the correct card (ah wait apparently you did that, does refreshing the firefox tab after doing that help?). I'd completely expect that switching the sink to the "usual sound producing family sink" will not produce sound anymore, because jack is now handling that device. Maybe post during that situation

sudo fuser -v /dev/snd/*
pacmd list-sinks
pacmd list-sink-inputs

again.

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

The screenshot from Catia shows the default configuration (I didn't touch anything). I don't know how to ensure that it's routed to the correct card but if you think the routing in Catia looks good would that be sufficient?

Refreshing tab or restarting Firefox does not help.
(inadverently) restarting pulseaudio has _some_ effect: in pavucontrol there is now only the "Jack sink" output device, not the Family one.
(what really happened was: In Cadence I pressed "force restart", after which pulseaudio stopped working so I had to kill it and restart it, after which I could "Start" JACK in Cadence)

Edit: as it is a less common situation where I have to force restart pulseaudio, this is the output after I reboot, start firefox, play a song, start JACK through Cadence, and set the output sink of Firefox to the Jack sink. Quite a lot more verbose, as it usually has 2 sinks:

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

In pavu control, what is in the Configuration tab for the built-in audio?

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

I think pulse is fine, jack is currently not routing properly, but I'm not entirely familiar with jack (yet) so I'm unsure by what metric you need to connect the jacks.

Can you post a snapshot of your Cadence and Catia settings again?

Re: [SOLVED] Can't set up PulseAudio + Jack with Cadence (no sound, xruns)

Looking at Cadence settings I found that it was using Digital output so I tried Analog and now ALSA+PA+JACK works!
Thank you both very much!
