hello

im having a back and forth coming "hum" or buzz in my monitors when i use my babyface. it comes when the output is set to a certain level, around 70 %, then it goes away. even if im not playing any music.

i also very randomly have problems with digital strange sound on recording. bought my babyface in december and have had 2 very strange digital sounds when recording music.

if i press on the dock of the breakout cable, it goes away. or sometimes gets worse. if i screw the screws harder it goes away or comes more.

i have a macbook pro 2010 model. and grounded electricity in my house.

i have no clue how to fix this. i assume its some sort of lack of contact in the 15 pin connection?
how hard should i screw the two screws?

otherwise its great.. Just breakout cable blues. and if that cable/connection dont work, i cannot use it.
