Thanks for all the info.  I went back to Best Buy the other night and was told I had to bring the TV back within 15 days, not 30 so I guess now I'm stuck with Samsung support (sounds like a dead end) or something like the Caavo box.  Funny, I read him you message about the Caavo box solution and he didn't mention they sell them.... I'd probably have just bought one while I was there.   I'm a little confused on the Caavo solution.  I see the picture on the site shows 4 HDMI inputs and an OUT to  "TV/AVR".  If I understand right, you send the OUT to your Onkyo and then it outputs to the TV?   In my case, with a soundbar their setup video seems to indicate I'd still have to leave the soundbar plugged into the TV's HDMI ARC which means I'm likely to have the same problem? https://www.youtube.com/watch?v=IZzgkavVb_U   ...
