In the middle of the gig, Traktor started playing crackling sounds when touching touchpad of the laptop. It occurs only when fader for any channel is up.
Afterwards, I tried removing Traktor 4 and installing 3, disabling everything from device manager you can think of, playing with latency settings, turning off discrete graphics, etc.
I can't resolve the problem.
I used it for a year without any single problem and it started by itself tonight.
HP Victus 16-r0024nm Intel i5 13500 Windows 11
Traktor S4 MK3
Few versions of Traktor tried.
Laptop is very capable as I use it for power electronics design duties and it still doesn't stutter there.
