update appears to be from 2021! see pic above.... I just checked multiple times on my onkyo nr646 . FM radio, CD input, NET/Streaming works just fine when i turn on receiver and tv stays in art mode!! I switch over to samsung apps to stream netflix, as soon as sound is output from TV to receiver, input switches back to ARC input. This is resolved!
This update is not yet available on my model, looking forward to it! Also checked the Samsung download center.
