I also recently purchased a Q80T and also have a sound issue which is that when watching streaming content from the internet the sound cuts out for a brief second every hour or two. I have made arrangements for a repair visit thru my warranty for Samsung to investigate the problem but do not have much confidence.

I am experiencing the same problem with a 4k firestick attached to my 80T TV HDMI port #2 @userYI3qAxioMj wrote: I purchased a Q80T last month and absolutely love it, except for an audio issue that's been nagging me. I use an Amazon Fire TV Cube for my streaming. Unfortunately, sound cuts out completely for just a second or so, every so often. I haven't really found a pattern to it. I've looked everywhere online and I see others have had audio issues with the TV. How can I fix this? I've already changed HDMI cables, unplugged and replugged all cables, restarted all devices, and turned off a lot of auto detect settings in case they were causing an issue. What else can I do to fix this issue so I don't have to return the TV? where sound cuts out every hour or two for a brief second whenever I am streaming. Seems to be a problem with every streaming app such as HULU with the possbile exception of Youtube. I called Samsung support and the person I talked to said she never heard of the the problem and suggested that I reset the TV and/or the firestick. It sure would be nice if the Samsung moderator of this forum could provide some help.
