Audio connexion problem with MCX8000 and DJ Serato Pro


Sorry for my english I’m french. So for yesterday I have audio connexion problem between Serato DJ Pro and MXC8000 Denon Controler. First at all, I checked all informations on Denon and Serato Website. I checked all informations I found there. Drivers are ok, firmware are ok, I deleted and resintalled Serato DJ to be sure, tried with other USB Cable, etc, nothing worked. Before yesterday all worked, then one day after nothing worked. I’m not sure about that but i upgraded my windows 10 and it seems it coulb be because of that ? I have hp PC with windows 10. So i someone could help me, it could be good ! Txs by advance

In what way does the audio connection problem show itself?

Does the music not play at all ?

Does the music play but it sounds very “choppy”, or like it’s “underwater” ?

Does the mcx8000 play ok if you play music from a usb drive on the mcx8000 and ditch the laptop altogether ?

The music play with Serato. My computer recognize the sound card from MCX controler. Even I can ear the sound from my controler if I connect speakers at my controller. Just serato can’t recognize my controler because of audio problem.

does it load up the 2 virtual decks

do you get an error in the yellow banner below in serato…what does it say?

I have the same problem, I reinstalled the driver, check the firmware on the controller tried the troubleshooting article from Serato, etc… But still have the “Audio connection issue”…

@ainur @Bott have you find an issue for your problem? I have the same since i installed engine DJ. my USB driver it’s ok but serato can’t connect to my MCX8000 anymore

No issues ! I’m disappointed

I was able to troubleshoot my MCX8000. my serato can connect aingain to my controller and my usb driver is still ok.

  • Click ‘Start’ • Right Click ‘Computer’ • Click ‘Manage’ • Click on ‘Device Manager’ • Click on ‘Sound, Video & Game Controllers’
  • if you see: teVirtualMIDI - Virtual MIDI Driver, right click on the device, and click ‘Uninstall’
  • click ‘Uninstall’ on your device also
  • Unplug your device, restart your computer and try again

Do you use Windows 10 or 11 ?

I don’t have virtual midi on “Sound, video & Game controllers”
