    Since the day i hooked up my home cinema system (denon receiver and a auna active subwoofer )there has been a hum and it only happens when i turn on something on the xbox or sky box but then when i turn my tv off it just goes away i have everything running through my receiver. A few months back someone in my house flipped the electric in my house and the hum stopped for around 4 months and i thought it was gone for good but now its just came back all of a sudden

    Does anyone know whats causing this????
