Just to update, found a way to "Dance around it" ;)
When I connect Next's analog audio out to my Soundblaster X6's analog input and it transfers it to amp, there is no extra noise on the sound!
.. that sounds like a ground loop issue? which would be weird..

Yes and even stranger, because they are on same power outlet. The point is, if there is an HDMI connected to Next and it to display, there is a constant ticking on amp. Even if Next is off and the amp is on different input.

I wouldn't be surprised if the soundblaster broke the ground loop. Discrete sound cards gotta be good for something..
