Tried all TV and box audio related option but still get the annoying buzzing sound. Only when selected the "undefined" audio instead of "English or Chinese" audio of each digital channel from the setup box sound option, the buzzing sound reduced a bit but quite significant especially for end sound like "s", "c" which turn to like "sss", "ccc" - could it be the audio format decoding issue?
Your box is providing power to antenna? Might be grounding problem. Try to find the option to turn the antenna power off but antenna remain plugged in.
