Xbox one S sizzling power noise
I have just bought a new Xbox one s and I realized, that when the machine is turned off, it has a sizzling noise probably from the internal adapter. I have tried with different cable and different sockets and still the same. I took it back to the shop where I bought it and we could not hear anything as the shop is noisy and the noise from the xbox is quite low, but am still worried there will be some problem with it. The guy told me I have to try to connect the xbox to an extension cable, rather than to socket. I just got home and tried, but still the same noise. Does anyone know what the problem is or any solution for that?
Thanks for the answers
