Every time I turn on my Roku unit it creates a terribly loud buzzing noise to My LG sound bar. No other sound comes through. To fix I need to unplug the power to the Roku and plug it back after approximately 10 seconds. Then every thing works normally. I do not understand why I this is happening and how it can be fixed. I bought the latest unit because this started happening on my old unit, and it worked fine for months but now worse than previous unit.
