I am using the USC-C docking station with a 13" touch bar macbook pro, everything works fine except the sound over the docking station’s headphone jack.
Every 30 to 60 seconds I get very short sound drop or stuttering, it is nothing too bad and not easy to notice at first but gets annoying after some time. When I plug the headphones directly into the macbook the issue is solved, so it has to be sound card of the docking station.
My setup: MacBook Pro via USB-C to docking station. Network cable, one USB and all three display connectors are used.
