This is my first smart television and I just can’t stop raving about it! All of a sudden it lost the HDMI connection. I turned the TV and Soundbar off and on, tried different HDMI cables again and double-checked that Anynet+ is on both the tv and soundbar, but it still will not connect to using the ARC HDMI port. Turning off sound device, power on the sound device (which to TV Audio), then turn on the TV, go to the menu, turn on HDMI-CEC and it works. The latter two are very useful features although a little buggy at launch. My question is what's the best way to wire it all up to get the best sound and picture settings as I feel that somewhere I'm not getting the best out of the system. I think I would like to do a reset on the soundbar but can't find any way to do it.turn off HDMI-CEC on TV, unplug Power to TV, ensure power is drained from TV (holding power button). I have a Samsung Q80 Oled 65" and a Q70r Samsung Hardon kardon Soundbar.

The Samsung Q80 is Samsung 2019 upper class 4k … HW-Q70R Soundbar.

So I happened to see this post and it sounded similar:I guess the issue is with the KS8000 TV and not the soundbar, or maybe it's a Samsung thing because I had a Polk soundbar hooked up to ARC for over 2 years with no issue. The Q70R is very responsive thanks to the very low input lag, and it supports FreeSync for nearly tear-free gaming VS Q8FN 8.5 The Samsung Q8FN has very similar performance to the Samsung Q70R.

after that when I set my soundbar to D.IN/HDMI ARC (my tv was already on tv arc) it connected and i finally heard sound. Samsung's latest Quantum Dot TV leaves John Archer feeling shaken and stirred The first new Samsung TV for 2019, the QE65Q90R [see HCC #298], was a stunner.

I reset the TV and went through the setup process again.As soon as I change the input on the soundbar to D. In, it loses the connection.Does anyone have any other suggestions?

Replaced receiver with a  HW-Q70R/XY soundbar and immediatley had problems with ARC dropping out and reverting back to the TV speakers.

I used the HDMI cable and hooked up ARC to ARC. HDMI-CEC enabled on TV using TV Arc with no issues at all. The TV only connects to the soundbar via WiFi.I tried swapping the HDMI cable with another cable.

At the moment, it’s not entirely clear how Adaptive Sound Mode differs from the company’s Smart Sound Mode (available on the The pair of soundbars make use of Samsung’s acoustic beam technology, which generates a wider, more immersive sound field through small, directional holes drilled into the speaker cabinet, and they are compatible with an optional wireless surround speaker kit.

Setting up a new TV may sound daunting, but Samsung's smart TVs are made to be user-friendly, including the out-of-the-box setup process. Samsung’s Q70R is one of four models in the company’s top-tier premier line of QLED series 4K TVs.

Updated firmware changed cables reset soundbar nothing helped.

Hope maybe that this might work for all brands of tv's for you all  that areexperiencing this annoying issue Once you hook up the FireTV 4k stick to the sound bar, does the tv show HDMI-earc when increasing the volume with the TV remote?

Samsung's HW-Q70R and Q60R can automatically change their EQ and other settings to better match what's happening onscreen, and are more affordable than the company's top-end line of soundbars.

Find here the best TV Settings for the Samsung Q80 (Q80R) from different well known sources. I have a 2016 samsung KS8000 tv hooked up to a HW-Q70R Soundbar. Turning off sound device, power on the sound device (which to TV Audio), then turn on the TV, go to the menu, turn on HDMI-CEC and it works.turn off HDMI-CEC on TV, unplug Power to TV, ensure power is drained from TV (holding power button).

Hopefully, I don't have to do this every month:  i was having this issue as well on my new LG Oled and HDMI arc.

... Samsung Q70R (2019) The Samsung Q8FN has an antireflective filter that provides much better reflection handling in rooms with many light sources.
