I have a MAG254 STB. I am having issues with the audio quality coming out from the TV box, especially when I try to listen with headphones or speakers connected to the headphones output at the back of the TV box. When I plug the headphones/speakers 3.5mm jack to the MAG254 I feel really high noise interference. It's like a constant cracking sound. I tested my headphones on another devices like phone, tablet, etc, and they were okay.
Can you please tell me if the TV Box is faulty and should be replaced, or the reason lays somewhere else.
