i connected my macbook to my marantz receiver st7001 via an mini dvi to hdmi converter. the sound is set to come out of the mini toslink port and i just got the cable from monocable. i am getting a lot of static showing up my my panasonic? when iam in my office i use the same port mini dvi port to connect to an external monitor. i have a converter in my opffice that goes mini dvi to dvi? could it be the cable?
