It's been years so top post (make a new post) and always call Samsung and Netflix when their product fails. Otherwise they won't know it's busted.
I noticed that there has been a recent update to the netflix app on the Samsung smart tv. Since this time, shows will start off playing audio just fine, however the audio either drops off intermittently or completely at some point. If I pause/rewind, the audio tends to come back, at least for a bit of time. I do not have audio drop-out issues with hulu or amazon video or when watching a blu-ray, so I believe this is a problem with the Netflix app exclusively. However I was wondering if others may have found a solution.
