Samsung 43" TU-8000 Series 4K TV

I don't know which is more to blame, the TV, or the SAMSUNG HW-T450 2.1ch Soundbar with Dolby Audio (2020) (https://www.amazon.com/gp/product/B085WTFCQ7) that I got to pair it with. But it has a serious flaw with audio. I've described the flaw in more detail in my review of the soundbar. Bottom line is every 30-60 minutes the audio goes completely off, the "D-In" light flashes on the sound bar, then the sound comes back a second or two later, often at a lower volume than before it went off. This despite being connected to the soundbar with a digital optical cable that came with the soundbar unit. I have spent a dozen hours hunting for a solution and have found none. I'm about ready to toss the Soundbar out... since it is past my return window. The problem seems to occur no matter what the source is... whether streaming through Fire Cube TV, or directly from an App in the TV. Note that my TV and my Fire Cube have direct ethernet connections, so there is no problem related to WiFi. Also, if I turn off the sound bar and use the tinny, tiny speaker in the TV, it doesn't lose audio. And if you end up with some volume on both the TV and the Soundbar... chances are very good that they will be OUT OF SYNC. In short, two Samsung products do not play well together. Our previous TV was an LG. The smartOS on the LG TV was a nightmare to operate, on the Samsung, the TV is much more navigable, except they seem to insist on having their "advertisement" as a necessary, and unavoidable / unremovable thing you must ALWAYS skip over to get to the settings. This isn't really a surprise, Samsung cell phones are loaded with similar unremovable, unwelcome junk. While you can enable Alexa (and/or Google) on the TV, you'll be sorry if you do. You get much more, and much more accurate control via an "Echo Dot" or better, a Fire Cube TV (the Fire Cube is far from ideal, too, by the way) The good news is... you can add the apps for eg. Netflix and HBOMax directly to the TV. This is nice if you don't have Fire TV, and it works. But you'll undoubtedly find it much easier to use the Fire TV controls/remote than to try to use the one that comes with the TV - assuming you pick up the right remote! Unfortunately, the Soundbar remote and the TV remote are nearly indistinguishable. The TV remote has 4 more small buttons, but the extra 4 buttons on TV remote are really, really useless. On my TV remote, you have "Netflix, Amazon Prime, Samsung Plus TV" - three direct streaming channels that you cannot change. It also has a silly "color mode" button that I can't imagine ANYONE would ever find useful on the remote... but the TV Remote lacks a "Go to Settings" button. Geez, even the LG tv had such a feature. If you want to change the subwoofer volume or the sound mode, you'll need to find the soundbar remote. If you want to control the soundbar volume, it appears you need the soundbar remote - which has a prominent mute button whereas the TV remote does NOT have a mute button (Hint, it actually does, but it's really non-intuitive - it's certainly not labeled - which again is why I find the Fire Cube remote to be MUCH better overall.) Picture quality has been good, but doesn't seem better (in fact doesn't seem to be as good as the elderly 4K LG TV that it replaced). It's hard to say how much of the problem is due to bandwidth limitations in streaming vs TV cleverness... I haven't reconnected my over-the-air antenna which is where the LG was very noticeably sharp. Lastly, while Samsung products are generally good quality, their huge land grab at gathering personal information rankles me. I'm not a fan of sending my personal information to a Korean company that seems more interested in selling me things (and selling my personal information) than in providing a quality product and quality service. UPDATE: over time audio sync has grown worse. Leave it on for 4 or so hours and the sound will lag the video by up to 2 seconds. It's horrendous and it happens regardless of source (broadcast, Fire tv or local streaming) and regardless whether using the soundbar or not. Some sources require setting the volume to 70 to be audible. DO NOT RECOMMEND this device.
