After I installed v1.0.3: Channels 2,3,4 don't work anymore

Hello, there. It’s 2021 and I start DJing again, after Corona.

Now I’ve got a problem with the following settings:

  • I use the MC6000MK2 controller with the new software v1.0.3
  • I use Windows 10
  • I both tried the compatibility of the software with Windows 7 and Windows 8
  • I tried Serato DJ Pro, as well as Serato DJ Lite and Serato DJ Intro

And that’s the problem that’s happening: (Channel 1 runs perfectly, but then…)

state 1: After I first installed v1.0.3, the channels 2,3 and 4 weren’t able to produce any sound from the signals they were getting from my PC.

state 2: After I installed v1.0.3 again, the channels 2,3 and 4 produced maximum sound from the signals they were getting from my PC. This sound couldn’t be regulated/lessened, neither for the master ouput, nor for the booth output, nor the monitor headphones outcome.

state 3: After I installed v1.0.3 again, it was like state 1 again

state 4 after I installed v.1.0.3 again, it went like state 2 again.

And so forth. It switches from making no sound to making maximum sound.

Does anyone of you can help me to make every channel work just as good as channel 1?

Best regards
