Reply to Reloop Digital Jockey 2 Interface Headphone Noise

Hi guys,

recently I've been having trouble with my Reloop controller. Sometimes (for no apparent reason) when I have my headphones plugged in, this really loud noise suddenly comes through the headphones (some sort of buzzing noise) and it only makes this noise when the headphone vol. is 0. When I try to play music I hear nothing through the headphones when the volume is open and when I close it, I immediately get this buzz. It's not the headphones, I know that, and when I restart my laptop the noise is gone. Does anyone know what this is?

Also (another problem) when I enable 4 fx units in Traktor, the cpu load suddenly goes through the roof. I this normal?
