NUC name it I like you is the problem. But I understand that speakers get noise. Is this correct?
If so, what I was saying is that it is possible that magnetic fields exist in the air and near the speakers and proboquen affecting noise.
Now if you do a test with the same but you change the situation and the noise does not occur. Things change because it is impossible to be a magnetic field. Do not you think?
mhm, only NUC, speakers and monitor powered on--> noise
still sparkling noise and a supply noise
when i power off the NUC its almost quiet and when i`m surfing the internet, horrible
so i guess a driver or the network interface is causing this, my faulty.
used the windows/ realtek driver--> no difference
