Apple tv 4k sound issues on various apps.

The Apple tv 4k apps like netflix , amazon prime video, disney+hotstar, etc. seems to have no sound while watching any series episodes moving from one to another episode having dolby atmos enabled in auto mode in settings. When dolby atmos is disabled everything works fine with sound. Its been long apple has not fixed this issue or are they even acknowleding this as an issue? Its a very expensive product back here in india and the advertised dolby atmos is not working as expected. M on top of the end subscriptions for all the apps mentioned. Please fix this asap or take this product back if you cannot fix this issue. I think fire tv devices offered at a much lower prices will have better dolby atmos capability.
