How to fix freezing s4 mk3?

Hi,

I bought a new s4 mk3 but there are problems with it!

When I run Traktor pro 3 (3.6) on my laptop without the s4 mk 3 connected there are no problems, I can play 4 decks at once and the audio is good no pop, cracks, glitches. Also latencymon shows that my laptop can run the software without any problem.

But when I connect the s4 mk3 the problems start. First everything works as it should, the audio is good, the controller works normally. But after a few songs I alternately experience 2 kinds of problems!

1. The audio stops suddenly but the software and controller continue to work as they should, but no audio comes out of the speakers or headphones.

2. The controller displays freeze and the LEDs of eg the cue or filter button react slowly. But the music continues to play normally, and the midi inputs of the controller are also detectable in the software.

I've tried everything I can find on the internet but nothing seems to help.

What I've already tried.

-new USB cable

-put laptop in high performance

- all drivers updated

-installed the asio driver for the s4 mk3 -tried the wasapi exclusive -all power saving options turned off

-disabled my bluetooth, wifi, cd rom driver etc.

-......

Does anyone have an idea? Could this be hardware related. The longest I've been able to mix was 1h30min but this was exceptional, usually the problems come after 10 to 20 min.

I have a Lenovo g50-80 8gb ram Intel i5 ssd

Thanks.
