BTW any HDMI cable will carry ARC, no special cable is needed for an ARC connection, To say "Samsung is not responsible for third party devices" is a brush off of the actual problem and that is proper programming on Samsung's end to make sure if they list "ARC" on their device, then ARC should work no matter what. That is kind of like saying hey my cable Box HDMI doesn't work on my new Samsung but my cable worked on my old TV and then dismissing the issue saying we aren't responsible for your cable box problem when the problem is Obviously the TV's problem. Hi, This is an extreemly annoying issue. There a numerous reports of this problem going back to 2017, with no real fix/solution from Samsung. Some report of the "10 minute solution" i.e. power down the TV for 10 minutes and the HMDI ports will reset - not really a solution nor very convenient when you have sat down ready to watch your favorite show!. Wanting a fix, but not being prepared to become a TV/HMDI/CEC geek, I have adopted the following $5 solution. Go to Walmart and purchase a Timer switch insert it into the power feed to the TV and set is to power off the TV during the night (or some convenient period when you don't watch TV). This daily automated power down seems to have worked for me, and cured my frustration at the same time. Hope it works for you too.
