I have a QN90B Samsung TV with significant eArc issues using a Yamaha A6A receiver. I believe the Samsung QN90B and A models TV's have a major software and/or hardware critical defect with its eArc system. The Samsung QN90B eArc problems started as soon as the Yamaha A6A was connected to the TV. Performed extensive troubleshooting tasks over the span of 3 weeks with the help of experts from Yamaha's help line and they rightfully concluded that it was the Samsung QN90B TV having eArc communication issues with Yamaha A6A receiver. Unfortunately the facts are now building that Samsung’s QN90B and A models TV’s do have a consistent and systemic defect in their eArc system that they need to fix as soon as possible.

Summary of Troubleshooting Tasks:
I've got similar issue.. I'm using Samsung qe55qn90b with Sony HT-RT3 soundbar connected via HDMI (eARC->ARC). Everything works fine, samsung remote works well with soundbar so when I turn on TV then automaticaly soundbar turns on and volume works too, exactly how I want, BUT there is a sound skipping every 10s and that is soo anoying.. I noticed that only thing that can help is take a soundbar remote and switch input to another and switch it back to TV. But I have to do it after every turning on TV, otherwise I'm getting theese sound skips. I tried different hdmi cables, all TV's and soundbar's settings, disconnect all cables from ports and from AC power, nothing helped.. The soundbar works without any problem with my old LG smart TV.. Samsung obviously have a problem with their HDMI eARC ports .. I hope that Samsung will release some update that will help. If not, I'm not sure I'll buy another Samsung TV..
Just bought QN90B 65" - used to have old Samsung TV which worked fine with my Samsung J450 sounbar for years with HDMI port... currently, eArc disconnects every few seconds. Replaced cable, updated firmware - nothing works. I am frustrated... sorry I got this model.
I have just taken delivery of a Samsung TV 65" S90C OLED 4K Smart TV (2023) and Samsung HW-Q930C Q-Series Soundbar (2023).
I keep losing the connection to the Samsung Soundbar via the HDMI (eARC) connection.
If I disconnect everything, then just connect the TV to the Soundbar via HMI eARC, it will work for a while and I can select Q Symphony so the TV speaker and the HDMI eARC setting is enabled and active, and the audio output changes to reflect the use of the TV as well as the Soundbar, but when I then turn off the TV via the Samsung Remote and turn it on again, it does not find the Soundbar and I am left with TV Speakers only.
If I power off, disconnect then power up again it will eventually find the HDMI eARC before dropping our again after I turn off the TV. YAWN. Do I have to do this every time I want to use the TV???
This is sooooo frustrating with brand new equipment that is meant to seamlessly integrate.
Very, very disappointed.
Same exact issues here with a Yamaha AVR. Unplugging the TV sometimes resolves it or a short period of time, but it always comes Baki, and I also can’t easily get to the word behind the TV.
TV is brand new. Very disappointing.
