[GNU/Linux] No sounds using DDJ-400

Remake January 10, 2021, 5:28am #1

Hi,

First of all, I am new to the Mixxx community and I would like to thanks all Mixxx contributors for their amazing work

I am having an issue when I connect my DDJ-400 to have sound. Ideally, I would like to use my computer speaker as a master and the DDJ-400 channel for the headset. But when I try I have no sound from the computer speaker and from the headset connected to the DDJ-400.

Some details about my setup :

I am using Manjaro
I am using Mixxx 2.2.4
I am using the DDJ-400 mapping from Pioneer DDJ-400: Address outstanding issues by jusko · Pull Request #3479 · mixxxdj/mixxx · GitHub
pwd /home/remake/.mixxx/controllers ls
DDJ-400_----_4.hid.xml Pioneer-DDJ-400.midi.xml
DDJ-400_MIDI_1.midi.xml Pioneer-DDJ-400-script.js
Looking at the Mixxx wiki I configured my user to be part of the “users” group and I have the udev rule file:
$ ls /etc/udev/rules.d/mixxx-usb-uaccess.rules
/etc/udev/rules.d/mixxx-usb-uaccess.rules

The first strange thing is that Mixxx finds “two controllers” instead of one (I never created the files for the "DDJ-400-----_4 controller)

This is the setup I have in the Sound Hardware menu where I am not able to see the DDJ-400 controller (I used to be able to see it even if it didn’t work neither):
Screenshot in the second post as I can only add one to this post.

Here are the Mixxx.log:

About multiple controller entries: Don’t worry. That is normal in many controllers. The correct one is the MIDI one. The other is just an HID interface which is not needed.

About internal soundcard not having sound: It might be that your system uses pulseaudio or JACK.
If it is the former, try to launch Mixxx with the pasuspender command ( pasuspender(1): Temporarily suspend PulseAudio - Linux man page ). Of course, that will make the audio of all other programs to stop.

About the DDJ400 not appearing as an option, I don’t know. I don’t know if you need support from the kernel, or what. Maybe other linux users could help you there.

If you click on Master in the Sound Hardware settings, the ddj is not listed in the dropdown menu? Not sure if you know it or i’m explaining you things you already know, but you have to tell mixxx which soundcard (and channel on this soundcard) you want to use for which stream. Master should go through the main output of your ddj and Headphones through the cue/headphone output of your controller. If mixxx doesn’t detect the ddj 400 as a soundcard, then it’s another problem.

Thanks to both of you.

@JosepMa : I tried to launch Mixxx using pasuspender and unfortunately it didn’t improve the situation. But pasuspeneder itself works as I lost the audio on other program.

@obsoleszenz : My bad, I realized I pasted the wrong screenshot hence why the DDJ-400 was not used as a soundcard. Sorry for that. Here is the correct one:

With this setup I expect to hear the sound from my headset connected to the DDJ-400.
I don’t have monitors/speakers connected to the DDJ-400 so obviously I won’t hear sound from here but my understanding is that the headset should work and it doesn’t.

Because I don’t have monitors that I can connect to the DDJ-400, I would like to have the “external sound” going through my computer speaker and using my headset connected to the DDJ-400 if this is possible. What Pioneer calls “PC Master Out”.

Do you think this is feasible ?
Thanks.

Just select your internal soundcard for the master. This way cuing/headphones will go through your DDJ 400, the master sound through your pc speakers or whatever you have connected.

Is the controller working with rekordbox? And do you have the cue enabled for a channel? Checked that the cue volume is not zero? Do you know how to use a dj controller? Sorry for probably trivial question, currently unsure where to start finding problems. The setup from your sound hardware looks good.

Like that ?

I don’t have a Windows/Mac OS computer with me to try but the DDJ-400 controler is able to control Mixxx with the mapping and when I quit Mixxx but let the DDJ-400 connected to my computer with a headset I am able to hear the sound trhough the headset so I believe the DDJ-400 works.

I am very new to this but I think I did it correctly on those points. I will post a screenshot of the Mixxx GUI so we can be 100% sure I did.

0 need to be sorry, you are actually helping me
And you are very right, the probability that I am doing a beginner mistake is actually pretty high so checking everything is definitively a good idea.

…also right-click the HEAD MIX and HEAD knobs at the top to restore the default positions.

And don’t touch the MASTER knob. If your output through the pc speakers is too quiet use the system audio mixer to adjust that (but there, too, try not to exceed 100% volume, it may cause clipping)

Thanks for the advices ronso, I will follow them.

Don’t worry, I had the same type of problems in the beginning too. No audio and 100 possible causes for this is always a bit complicated. But you will know them soon and see it quickly what the problem could be Enjoy mixxxing!
