I have a Samsung UE55TU8000 55` 4K UHD Smart LED TV with a Denon DHT-S216 Black Soundbar I have them connected via an ARC HDMI connection all works well and volume on the soundbar works on TV remote. The LEDs on the sound bar indicates TV (ARC) 2 lights. The problem starts when I change source say to my firestick the 2 LEDs stays on the sound bar indicates TV (ARC) and all is working perfectly but if I switch back to terrestrial TV on the television. the soundbar reverts back to 1 LED the sound bar indicates HDMI and no sound comes from the soundbar. The only way I can resolve this is to manually switch the back to TV (ARC) on the soundbar remote. The 2 led lights come back on and I have sound. I can change channels and even switch on and off and all is well it is only when I switch to a different source and back again I get this problem. Its driving me mad. I have contacted Samsung and Denon with no luck
Gentlemen from Denon Romania, recommended me to buy an HDMI 2.1 cable because the Samsung TV has an eARC port! I will order one before I send it as a guarantee or I will return it!
Just putting this here as I used this as a solution and whilst not ideal it does work. I had the same issue while using my PS5 in HDMI and using my Denon Soundbar via HDMI-Arc. I instead plugged the PS5 directly into the HDMI in of my Soundbar and manually switch to the PS5 via the Soundbar's source option on the TV. This allows me to select the Playstation via the Bar rather than switching via the TV's HDMI inputs. Seems to work now and the Soundbar doesn't switch over to HDMI when changing between channels or Apps on the TV.
Same problem. For some strange reason i could switch sources for 2 weeks and soundbar worked fine. I connected a DVD player Just for testing. Disconnected DVD player and now when i switch soorce as Netflix or change TV Channel the soundbar goes back to One led.
try disabling anynet+(HDMI -CEC) , connect hdmi cable, and then put power on your sound bar and enable anynet+(HDMI-CEC) option in your tv and enjoy it the sound bar!
Yeah. I tested the soundbar on another TV (an old Sony btw) andno problem. I guess It Is the Samsung TV that Is somehow defective . Unfortunately Samsung dont care.
