Samsung HWQ900A + Samsung SWA-9500S rear speakers (1 Viewer)

Hi all!
I just bought a Samsung HWQ900A and a pair of Samsung SWA-9500S speakers.
I connected them properly. My problem is the rear speakers are only used during videos on youtube. In other cases, like playing Xbox Series X games or watching movies on Tv via external hard drive, I cannot hear any sound from the 2 rear speakers.
I set up the best settings for the soundbar on the Tv (LG OLED55 B9SLA), including digital sound output on "Pass through", enabled eArc. I also set up the soundbar for best settings: auto equalizer on, ava on and increased the rear speaker level to 6.
I watch movies with Atmos support and 7.1 on Tv via external hard drive and still no sound from the 2 rear speakers. I tried all the sound modes on the soundbar but nothing works.

Any idea what is wrong?

The "Pass Through" setting might be the problem. You probably need to enable Dolby Surround or Neural X on other sources to have the soundbar synthesize rear surround channels. You need to be playing back one of those sources to enable that setting.

Thank you for your help. I changed the digital sound out from "Pass through" to "PCM" and now the 2 rear speakers are working. I don't get it. Every website I searched was writing that "Pass through" was the best choice. Now it turns out that it is not true.
I know it sounds weird but now with the 2 rear speakers in "PCM" it sounds more quiet than in "Pass Through" without the 2 rear speakers. Is it normal?

And one more thing. The "DTV Audio Setting" on TV should be set on Auto or one of the followings: MPEG, Dolby Digital, Dolby Digital Plus, HE-AAC?

Auto, most likely.

...but give the Dolby options a try.
