Onkyo TX SR 444 ATMOS

Apparently dolby atmos will only transfer through hdmi and not optical,i was just wondering whether it is something to do with hdr

Do you have "let receiver decode audio" enabled in Settings > Disc & Blu Ray > Blu ray?

And after that go to Settings > Display & Sound and go, under HDMI audio, to Bitstream format and select "Dolby Atmos for home theater".

After doing this the blue light for Dolby Atmos should be lit on your receiver when it is decoding Dolby Atmos input.

Have you tried the optical SPDIF in and not used the HDMI passthrough?

Like have the TV and Xbox directly connected and have the optical cable from the Xbox to the sound system?

Any news on this yet?

XSX->LG G1->Onkyo TX-NR686 same Atmos audio lag/delay as OP.

Hey. I had purchased an Onkyo TX-NR797 just before Christmas and it wouldn't stream atmos from my Xbox One X nor Netflix atmos movies from my Apple TV. I had update the firmware during the initial setup and I'm strongly thinking that's the issue. After playing
around with it for over a week, I had it exchanged. I was in a back and forth email conversation with Onkyo support to no avail. I didnt upgrade the firmware on the replacement unit and had no issues with atmos. I have an older Onkyo atmos receiver downstairs
and have no issue with atmos, nor with the Onkyo TX-NR777 which I recently sold. After communicating with Onkyo yesterday, i decuded to upgrade the firmware to the latest version (R113-0304-1131-0026). Now atmos isn't working with the Xbox One X but serms
to work ok with the Apple TV, where the previous receiver did not. I don't think it's the Xbox, but some to do with the latest firmware. Wish there was a way to downgrade. I connected my Xbox One S from downstairs to the TX-NR797 and still no atmos. Disappointing,
for I've used nothing but Onkyo over the years. I read elsewhere online where owners couldn't get any atmos devices to output atmos from the receiver. With other Onkyo receivers working fine and the TX-NR797 working piror to the firmware update, this eltells
me that the receiver is the problem, not the Xbox. Please contact Onkyo support and report this issue. The person whom I was communicating with said they never heard of the problem and that the unit may have to he sent in for service. Really?? He/she stated
they do not work in the engineering department and can't confirm nor deny if they're aware of or looking into it. Wish there was a way to downgrade the fw. You could on older models with older firmware versions thrught the web interface. I look forward to
your input and a fix from Onkyo. Cheers!
