I have reached out to a lot of these reviewers and they have stated, that they haven’t tested if it does but a lot of customers have tested and it isn’t. The reviewers are going to context Samsung for some clarification. So all in all not even the reviewers know if it is even though they have stated it.
Just wondering, did you set Dolby Atmos ON and HDMI ARC | Pass Through or Auto? What about DTV settings? Could you give me some details about all your sound settings?
Sure, so I have the LG c9 that has eARC that’s turned on even though it doesn’t need to be considering the soundbar isn’t eARC. I have the soundbar directly connected to the tv hdmi arc port for all sound from all devices. It’s set to passthrough and al the HDMI ports are set to bitstream (LG c9 currently doesn’t support pcm multichannel) though an update is coming next year to fix this so don’t use the tv’s pcm as you’ll just get 2 channel audio and nothing more. DTV is set to auto and under the sound options ensure Dolby atmos is on I don’t know if it’s greyed out now with using the soundbar for sound over the tv speakers. And that’s pretty much my set up. I’m using a 2.1 hdmi cable. I get Dolby atmos on Netflix and Apple TV 4K all be it lossy audio from DD+ with it not being eARC.
I’m not entirely sure, I’ve kept mine on passthrough as this wasn’t an option on the C8 so I just thought I’d passthrough was a new setting for arc this year then I kinda thought it must be the best option for eARC use not that it matters currently.
Reading the manual I think that "Passthorogh" option is basically to support DTS-HD codec. If you don't need it then try to switch "Passthorogh" to "Auto" and see if it changed anything.
I have tried both and they don’t make much difference. My tv might be eARC but the soundbar isn’t so HD audio passthrough cannot happens as arc will not pass HD audio just standard compressed audio. That’s why I wanted eARC and it can passthrough uncompressed 5.1 and 7.1 wheres arc can do compressed 5.1 at best.
HDMI ARC bandwidth is 1 Mbps EARC bandwidth is 37 Mbps which is a massive difference and why eARC can support HD audio and lossless audio and arc cannot
I’ve literally just posted this on a new topic I created myself and others got together to get this sorted and make Samsung sort it out. And apparently they now are. 🙌🏽🙌🏽

Shouldn't passthrough mean more/less the same as PCM? As I understand, Auto mode meas either PCM or Passthrough. What's the point?
