Hi there,
I got a response back from Samsung assistance in which they blame the optical audio receiver.
They made me do some tests with other receivers and since the problem stood still they passed me through other levels of "expertise".
At the end of the story, in front of the objective evidence of their software bug (buffer, codec, signaling, whatever...) they said that all receivers I tested were not officially compatible. I tried to explain that is a standard they should reference to and not the receiver, but they were completely depth to the standardization topic.
Disheartened, I asked what would a "compatible device" be and they answered me that the Samsung soundbar is, which works on bluetooth.
I thought they were joking and wasting my time and since I'm an engineer, I asked to "the assistance" for the optical toslink compatibility specification sheet. They just closed the ticket and never answer to me again.
Honestly, I think this is the worst way to handle a bug. I do understand there in no interest in updating a TV that is going to be old in few months, but neglecting an issue that is wide spread is the worst kind of publicity they could do.
Sorry guys, I am more than sure that this is not going to be sorted out. We might have to ditch the optical toslink port and buy a receiver that supports hdmi arc, hoping that this issue does not afflicts that too.
Of course in the future I won't even consider buying another Samsung device and will advertise against every client, friend and will report on social media, too.
