A) don't use the PC on PSU
B) if you're connecting over analogue audio, lift the ground off the audio cables on the PC end.
C) if you're connecting over SPDIF, use optical, not coaxial.... OR, get 2 optical/coaxial converters anda really short optical cable, , and out them between the PC and Mac audio devices coaxial SPDIF I/O , so you have no electrical connection....
basically, lift the signal (NOT power) ground between the PC and Mac, and it should be sorted.
Hi, sorry for being thick but not sure on how to "lift the ground off the audio cables"?
So in response to your q's
A. I have to use the PSU on the PC laptop as battery is dead, so it needs to run on power im afraid, so thats a necessity.
B. Not sure on how i do this or what that means?! Sorry for being dense but does it mean lifting the cables up in the air? lol
C. Not connecting via SPDIF
Its an analog out Mac to Analog into USB Soundcard on PC, and I get this noise, so any help on "lifting the ground" would be a big help - i'm already with my spade if that helps?
