Not sure if anyone can help, but I have my laptop running through my Roksan K2 amplifier. I have it connected via the headphone out on the laptop into 2 rca into my amplifier. When the laptop is plugged into the mains, I can hear a hum/buzz coming through the speakers, however, it doesn’t do this when the laptop is running off the battery.
Just to make sure it wasn’t the amplifier I connected the laptop into the inputs on my dvd recorder and could hear the buzz through the television where it was playing through the dvd recorder. The strange thing is that I tried it on my old Nad c340 amplifier in another room and it didn’t seem to do it.
Can anyone help me with this problem? From what I can make out it must be the laptop.
Any help would be great.
