Glad to hear you solved your issue!

I tried working with A&H support on the updates and they have been very forthcoming in trying to resolve the issue with the tools they have available.
For me this had no effect sadly.

Actually there are three different tools to use on the DB4.

– Mixer firmware
– soundcard firmware in the DB4 (ploytec)
– driver

@Oxy,

This is similar behavior to what causes the crash on my AMD machine.
When turned on prior to starting the PC this doesn’t happen.
But still, the sound hangs/youtube doesn’t play/network errors keep rising thus making the machine problematic.

I Sold my DB4 today, got a fair price fr it, will look into a new mixer.

[EyreonParticipant]

Alright,

Minor update from my side, I will ignore Volounteer, since he is only trying to point at m,y initial problem. not helpful.

I have now been able to reproduce the problem on 6, 6!!! machines, all running AMD Ryzen.
I tried 4 Intel machines and no problem.

I know without a doubt, the problem is the Ploytec driver that comes with the DB4.
The error message on BSODS stating it and being able to reproduce this makes it clear.

I can also pinpoint where the problem is located in the way the driver functions.
This has to do with the different ways that AMD and Intel handle their memory access and use of the CPU fabs on AMD.
Should not be a big issue to fix but I can see that investing that in a mixer that is still being sold and made is too much.

It pains me to say that ill have to get rid of the DB4 and go for something else like the Xone:96 which is core compliant and doesn’t rely on 3rd party shizz.
Shame I have to dish out another smack of money for something like this 🙁

@volounteer

I am wondering if you are a serious troll or not?
I have written NOTHING about an X1… to start with.

The FACT that I can reproduce this on 2 separate machines running a ZEN platform makes it a logical deduction the driver is at fault.
Especially since both systems crash with the same message Xone_db4.sys has failed.
Tomorrow I will try a 3rd AMD-based system.

Please, keep to the data up there and not comment if your comment is not related to anything I have written and updated.

Both of you, id like to ask you to raise tickets with A&H support about the same issues you are having.
They are stating that this has been unknown until I raised a ticket and if they don’t have any other references other people might get screwed by this as well.

So what happened is simple, I have gone through pretty much every step there is to sort out and locate the issue.
Ended up reinstalling windows several times and with help from Traktor support found out there is an audio transfer problem.
It even got as far as a system crash stating that Xone_db4.sys was the culprit for the BSOD the mixer is generating.

I have been able to reproduce the BSOD on 2 different systems with the same steps, it being a B550 or X570 AMD-based system.

To recreate the Bsod on AMD B550/X570 Chipset machines.

On a clean windows install!

– Turn off DB4
– Disconnect DB4
– Install the latest DB4 drivers
– Windows reboots
– connect the DB4
– Turn on DB4

BSOD! stating Xone_db4.sys crashed.

So support went along and tested but found no problems (clearly pointing out this is an AMD only problem) and found out they are running an intel-based system thus no issues.
I have two systems available that I am willing to test with to sort the problem out but until further notice, my ticket has been closed with, in short: “sorry we don’t have any AM D systems to test with so we asked the engineers and Ploytec”

Now for a 99% certainty, I can say the problem is related to the outdated Ploytec driver…

In the meantime, I have a defunct piece of kit that I can do fuck all with in regard to digital mixing with software.

So I am deliberating what to do now since I mix both digitally with external drum computers, I had high regards toward A&H gear but this sure hit me in the groin pretty hard 🙁

Unsure now whether I should get a Xone:96 or go back to Pioneer.

[EyreonParticipant]

Allright I am now a step closer to solving this issue,

Support sent me a different firmware which keeps Traktor stable.
But now my system is having errors on the DB4 driver and either does weird stuff in my browser, causing websites not to load with a DNS error message.
Or it dies with a BSOD, which in terms of Windows 10 means there is big doodoo.

I will dig deeper with support.

[EyreonParticipant]

I agree,

Honestly, if the system is still being built and sold it should also have up-to-date drivers.
I am guessing because the driver development is outsourced this might be some cost, but support is needed with operating systems that evolve.

I have boiled everything down to it being the drivers of the DB4 now, I could rule out several factors because any other interface works fine.
RME fireface > works
Traktor Audio 6 > works

no crashes or weird system errors.

I have tried the db4 on both my Ryzen systems on an X570 and B550 chipset and the issue occurs.
I have tested with Intel platform and there is no issue (at least not on the 7th Gen)

[EyreonParticipant]

Awesome feedback,

That makes for 3x the same issue on ZEN chipsets.
The new AGESA update is not doing anything for me, I have been fiddling around on Friday and even went with yet another clean install, no effect.
This leads me all the more to IT being a driver issue with the DB4 provided drivers, they seemingly are out of date for this newer chipset and the way the chipsets handle their routing.

It kind of makes sense, the last driver update is from 2016, ZEN came on to the scene later. thus this is a key area to look at.

[EyreonParticipant]

So far, the X570 and B550 USB issues are resolved with the latest AGESA update from AMD, this does NOT solve the issue I am having with the DB4.
The USB problems are only on ZEN3, I am running a Zen2 (3700x)

I have isolated the problem down to the drivers of the DB4 being the culprit, sadly the mail I got back from A&H support stated there were no known issues.
Yet the problems arise after installing the latest DB4 drivers, all other USB devices work like a charm 🙂

I have also raised a ticket with NI since traktor 3 is crashing, they offer extensive tooling for system diagnostics to determine what is going on, I am hoping this hands me what I need to point out and isolate the driver as being faulty.
I have also sent them the error log that T3 generates, waiting for feedback now.

[EyreonParticipant]

I have and had 1 reply so far, this was a month ago.
I sent another mail last week and still no reply.

[EyreonParticipant]

I am guessing nobody else has any ideas, makes me sad I’ll have to replace this mixer 🙁
