Traktor Kontrol S4 Mk 2 freezes audio playback after a few minutes

soundsgood

Hi all, I bought Traktor Kontrol S4 MK 2 and I'm using it with Traktor 3 Pro and a Mac with OS 10.12. After a while of it working and playing suddenly I can't hear the audio anymore (sometimes immediately, sometimes after a quarter of an hour or half an hour), even though the tracks remain playing, the Kontroller still controls Traktor and the controller lights remain on. When this error occurs, I can't even play music from the Mac (e.g. from Spotify). I tried changing Mac, Traktor 3 version, latency, buffer, loader (trying to play even without loader), deleting everything and reinstalling Traktor and the drivers ("Traktor_Kontrol_S4_280_Mac_p"). Nothing. The only solution is to turn the controller off and on again every time. Has anyone already experienced this and knows how to fix it? Thanks
