ATMOS issues

[markm4663]

I have been having problems with ATMOS.

It's very intermittent sometimes and other times, will work fine. 

I have:

QN65QN90FAFZXA '24 and '25

QN75QN90FAFZXA '24

HW-650D Soundbar

HW-990F Soundbar

If you experience a problem, which includes no audio, intermittent audio, intermittent audio and then works, with Dolby ATMOS on any streaming service on a Samsung TV and ATMOS enabled soundbar:

1. Turn the TV off. If using a Google TV, ONN dongle or the like, use the dongle's remote.

2. Wait 15-20 seconds after turning the TV off and listen for a click on the TV.

3. Turn the TV on and wait for about 5 seconds.

4. Start your stream and ATMOS should be more stable. It might take a few seconds to stablize and the audio may actual drop out for a second or two.

Has anyone else experienced these issues?

That's music to my ears!
Thank you so much for moving things forward towards a resolution.
For 40 years I was a Systems and Integration Test engineer/director.
I worked directly with Samsung engineers on projects like OpenCable, tru2way, 3D and finally Open Connectivity Foundation.

Lately, I'm having the issue more with Apple streaming than the other steam providers, Netflix, Prime, HBOMAX, Hulu and Disney.
Yes, I'm having ATMOS problems with all of those steam providers.
Also, when I do get it working on the '24 TVs, when I change the volume, the ATMOS audio will go silent until I stop adjusting the volume and it comes back on its own.
