REKORDBOX CONNECTION ISSUES WITH DJM900NXS2 SOUNDCARD

Hello all.

 

I am having intermittent connection issues with a new DELL XPS 9360 LAPTOP, REKORDBOX and a DJM900NXS2.

LAPTOP SPECIFICATION:

I7 1.8 8550U
16 GB RAM
512 SSD
ALL BIOS AND DRIVERS UP TO DATE
CLEAN COPY WIN 10 64BIT
NO BLOATWARE

The problem is that even with latency set to (1920 samples) and the playback sample rate is set to minimum (44100HZ) i have pops and clicks and disconnects.

I may have one pop or click every 10 mins

I may have one disconnect between 1min - 1 hour apart

To allow me to continue work i must re-initiate the connection to the DJM sound card.

The laptop is new, it has a clean version of windows 10 64bit installed on it.

I have done an abundance of things to try to stop the disconnects and the pops and clicks but nothing seems to work.

Please see this extensive list below detailing what i have tried so far, each time with no result.

Change USB cable
[FAIL]

Disable SPEEDSTEP and C STATES from within the bios.
[FAIL]

Enable minimum an maximum processor states from within the power settings, putting everything to 100% to make sure there was no chance that the processor would begin to drop its speed and therefore make the audio drop out.
[FAIL]

Next I re installed Windows 10 from the Microsoft site.
[FAIL]

Next i installed all the drivers & hardware updates from Microsoft & Dell that corresponded to this laptop
[FAIL]

Next i considered that the two blue USB ports shared the same host controller and using an external hard disk and having the ASIO sound card connect to each port would cause a bandwidth issue so i moved the audio to the internal SSD drive.
[FAIL]

Disabled on-board audio from bios
[FAIL]

Disabled on-board keyboard back lit from bios
[FAIL]

Disabled touchscreen from bios
[FAIL]

Disabled camera from bios
[FAIL]

Disabled SD card from bios
[FAIL]

Disabled TPM audio from bios
[FAIL]

Disabled virtualization from bios
[FAIL]

Disabled wireless LAN from bios
[FAIL]

Disabled Bluetooth from bios
[FAIL]

Disable the ability for windows 10 to turn off a USB device to reserve power from within the control panel.
[FAIL]

disable firewall
[FAIL]

Disable Windows Defender Virus Threat protection

[FAIL]

Disable system restore
[FAIL]

Disable all visual effects
[FAIL]

Scan all drives for problems

[FAIL]

I am at the point now where i have exhausted all possibilities that i can think of.

Does anybody out there have a clue where to start looking for a solution to this issue.

The only problem i have is the sound card disconnects from the computer or i have pops and clicks in the audio that is playing.

I have nothing running in the background,

Everything i can turn off is turned off.

This is the highest specification Dell laptop i could buy.

Everything is up to date.

 

Thank you in advance,

 

Justin.

I have the same setup as you do a DJM-900NXS2 & CDJ-2000NXS2's

If your are running rekordbox in performance mode this is what worked for me:

1.disconnect from the internet both lan/wifi connection, it's not really needed

1. make sure you are using the latest DJM-900NXS2 driver, you can download

it here https://www.pioneerdj.com/en/support/software/DJM-900NXS2/

and make sure you CDJ-players have the latest firmware updates, you didn't say

what your CDJ-players where?

It's not prefect, but I do get a lot of beeps and the mixer will  Freeze & lockup, if I have the lan/wifi connected, also I got better results with latency set to (512 samples)

and the playback sample rate is set to minimum (44100HZ)

not saying this will work for you, but it's worth a shot.

Hi, I am running in export mode and currently have the CDJ2000NXS2's disconnected.

I have the latest driver installed for the DJM.

I am running at the maximum latency and at 44100HZ.

Pops & clicks & disconnects between one minute and one hour

I think i have tried everything, including disabling wifi & lan.

Thanks for the response DEN :))

 

peace love and disco beats.

Humm... when I run in export mode I'm using 2 USB 1TB ssd's and I can run for hours

without any problems, it's the performance mode that gives me a lot of issues. but to me

the performance mode sounds better than the the USB-drives in export mode

(no need for a PC or Lappy in export mode) only in performance mode is when you can use the PC or Lappy

when you say the CDJ's are disconnected what do you mean?

are they pluged into the Laptop? and are you using any kind or USB hub

are a internet switch hub, those can cause a lot of problems that cannot

be resolved, I ditched all of my hubs, both CDJ's are connected to the laptop

as well as the mixers USB A plug... That only leaves me one USB plug left

on the lappy.

 I have my CDJ's disconnected to remove a possible problem from the chain, they are normally connected via LAN router

HUB to CDJ1

HUB to CDJ2

HUB to DJM

HUB to LAN

I am using export mode to play songs without mixing them, just to have a listen you know. I have turned on Performance mode and have the same issues.

USB:

there are three ports on the LAPTOP

two x USB 3.0 ports

one x USB c lightning port

the two USB 3.0 ports are shared with internal USB devices, one is a touchscreen, the other Bluetooth, as i described above i have disabled these two things and i have moved the music library to the internal SSD. This means that the only thing connected to the USB port is the DJM, no sharing internally or via external hub.

Justin listening to Natural Things by Innocence, tune. !!

Ahh ok, I see where your at now, funny thing is,

I don't any of what you describe while using export mode

it's very frustrating to spend a lot of bucks on this equipment

and have these issues, as each and every rekordbox update

I keep waiting to see a fix for these issues, but I not gonna hold

my breath, I may turn blue and DIED.

I run the laptop's sound card outlet into my mixer

and I always make sure It's using the lappy's sound card

to play songs in export mode like you describe.

it will be interesting to see what Pioneer say.

 

i wonder if it could be an issue with USB 3.0 on a USB 2.0 DJM

 

What i need is a measurable ability to test the issue.

Humm  I only have one USB 3.0 port on my Laptop, and that is connected to the DJM-900NXS2 mixer. I'm sure Pioneer will ring-in on this issue.....

It's entirely possible that the USB chipset / host is the problem, even with everything else you've eliminated. Can you find out which make / model is in use by your motherboard?

I have the same problem. I use my laptop exclusively for DJing. Latest drivers and latest firmware, all completely optimized for Dj software. Nevertheless, I have interruptions from the laptop to the CDJ2000nxs2. Whether USB 2.0 or USB 3.0. I use Windows 7 64bit. The standard answer is "your USB cable is broken" or "try it with a powered hub" everything brought nothing today. Whether Rekordbox DJ or Virtual DJ or Serato, it happens regardless of the software. Since then I use the Pro DJ Link and that works stable. I would like to use Rekordbox Dj in Performance Mode but unfortunately there was no solution until today. Devices for over 4500 euros and I can not use it properly. Sorry for my English, I use the translator from Google.

@Sascha > There are TONS of possible points for the issue to occur. With the fact your operating system is nearing 7 years old, and ended mainstream support 3 years ago. Perhaps it's time to consider upgrading the hardware / OS as it could certainly be part of the problem.

You may want to look at all the troubleshooting @jb tried in his original post, including updating your computer's BIOS (which I've seen correct a large number of these similar issues).
