Hello,
Is the main stereo line out from a laptop typically noisy? I am using a software synth and outputting the sound from the laptop to a multitrack recorder and getting an awful hissing sound. I thought it might have been a ground loop, so I tried using a DI box (Radial JPC) with a ground lift to eliminate it. It doesn't go away no matter what configuration I use. The only thing that makes a difference is whether or not the PC is plugged into a wall outlet. If it is plugged in, the hissing is unbearable. If it is just running on its internal battery, the hiss is still there but somewhat more manageable with noise suppression. So my question is, is this typical? or is there somthing I could be overlooking?
Thanks---------->
