[SOLVED] JACK2 Not Producting Audio on Fresh Arch Install

doctordeity · 2025-02-23 02:54:49

Howdy!

I just completed a fresh Arch install on my computer! I installed JACK2 on a couple of virtual machines beforehand, and it worked right out of the box. Unfortunately the same is not true for bare metal, and audio does not work on any program whatsoever. I am using an Alienware Aurora Ryzen Edition R10. I have sof-firmware installed, and I rebooted after installation. Everything is unmuted on alsamixer and volumeicon. Installing pulseaudio is NOT an option, because I want to go into audio production. I can try installing pipewire-jack, but that is a last resort option for me.

Here are some more relevant details.

Yes there's no information on your JACK setup. generally speaking, unless configured differently jack will default to whatever's your hw:0 since that is HDMI and you likely want any of the other 3 you'll need to decide which one's that going to be.

Assuming you want that scarlett, verify basic functionality with a

speaker-test -Dhw:3 -c2

if that gives you noise and that is indeed the device you want and assuming you're using jackd, see https://man.archlinux.org/man/jackd.1#d,~2

doctordeity · 2025-02-23 20:23:40

Howdy! Thank you for your response.

So funnily enough, that command did NOT work for the Scarlett.

speaker-test -Dhw:3 -c2

speaker-test 1.2.13

Playback device is hw:3
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Sample format not available for playback: Invalid argument
Setting of hwparams failed: Invalid argument

It DID work for my wireless headset and the one on my regular headphone jack, so this is the furthest I've gotten so far. That being said, I have another problem that I can't find the solution for online, and I fear it may be related.

Here are the contents of my ~/.asoundrc file:

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

pcm.jack {
        type jack
        playback_ports {
                0 system:playback_1
                1 system.playback_2
        }
        capture_ports {
                0 system:capture_1
                1 system:capture_2
        }
}

ctl.mixer0 {
        type hw
        card 2
}

I currently don't have anything in my /etc/modules.conf file, but to be frank, that's because I have no idea how to format it. When I try the jackstart command in the terminal, it tells me the command is not found, so I'm confused as to why the man page is suggesting using that command in the modules.conf file.

Alright, I finally got it to work. Someone on the LinuxMusicians forum suggested I install libffado.so.2, so I did. It still didn't immediately work, so I took a few extra steps:

1. I found this guide on JACK FAQs, followed every step, and rebooted my system.
2. I edited my ~/.asound.conf file like so:

defaults.pcm.!card "Wireless"
defaults.ctl.!card "Wireless"

and then rebooted my system.

Now my wireless headset and my generic headphones work with JACK. However... my Scarlett is being recognized by ALSA, as it shows up in aplay and alsamixer, but it does not work with speaker-test. The same error happens. Everywhere I look says it works out of the box, but clearly I'm missing something. The model is Scarlett Solo 3rd Gen.

Also, I am interested in learning how to easily switch output devices without having to edit my ~/.asound.conf file every time.

V1del · 2025-02-25 00:50:42

If you want to easily switch between multiple devices I suggest you get rid of all of this and switch to pipewire-{pulse,jack,alsa}, it has the actual and proper tooling to do this correctly.

doctordeity · 2025-02-26 04:11:05

OK! So if you're reading all of this hoping for a solution for just JACK, I'm afraid you are shit out of luck. Turns out I NEED pipewire-pulse to get my wireless headset's mic to work. All of that said, though, here's the journey I went on to finally configure everything exactly the way I wanted.

So first off, I want to state for the record that my Scarlett WAS being recognized the entire time, and thus it works perfectly fine. It just needed to be the default sink. Which made sense. I suppose my Scarlett did not like the stream parameters for the speaker-test; it says so on the error message. I don't get how all of that works, someone smarter than me can figure it out, but the important part is that my Scarlett works.

Next, I needed a way to easily switch between audio devices with a keyboard shortcut. Truthfully, that is what I wanted to do all along. So, I created a shell script and made it executable. Here are its contents:

#!/bin/bash

#sink list
sink1=alsa_output.usb-Focusrite_Scarlett_Solo_USB_Y7K500W9510750-00.HiFi__Line1__sink
sink2=alsa_output.usb-HP__Inc_HyperX_Cloud_II_Wireless_0-00.analog-stereo
sink_current=`pactl get-default-sink`

#change default sink
case $sink_current in
        $sink1) pactl set-default-sink $sink2 ;;
        $sink2) pactl set-default-sink $sink1 ;;
        *) pactl set-default-sink $sink1 ;;
esac

All I had to do at this point was to edit my i3 config file to run this script with a keyboard shortcut, and voila! It works beautifully.

I'm still brand new to audio production, so I'm sure this is going to come up again. When that event comes, I'll just make a new post.

Thank you V1del for all of your help.

Marking as solved.

You'll want to get rid of your asound.conf and install pipewire-alsa instead if you opted for this, so that ALSA using applications are also routed via pipewire instead of blocking device access by trying to get to it directly.
