so on the new Beta sound is working now 2025.22.0! got the update yesterday, installed it and tried it today. Sound working on all channels, no needing to tweak any settings, it just works. Although sound settings are still noticeably missing from Video & Audio in settings… But I’ll take a win. Now they just need to fix the speed of the app as it is so slow when switching between menu items and when loading the guide, or going into a show and selecting an item. However the no sound issue continues on AppleTV app in preview.
