Apple TV Apps. Some have no sound.

Apple TV 4K to Samsung tv. To Samsung sound bar.

works fine for some apps like Netflix and appletv+. Other apps like paramount, Disney, 7+, kayo all have no sound. Only recently started.

on 16.6 and there’s been no updates recently.

audio works if I disconnect sound bar. So seems to be linked to certain apps and surround sound setting?

tried forcing stereo or 5.1 in settings and neither works.
