The TV programs are only available in stereo from our sources. This will not change in the near future, although we are always talking to our suppliers about this. The same is true with Youtube content. On the other hand, the MyMedia app and possibly Netflix support multi-channel sound. In order to use it, you need to connect an appropriate decoder to the output of the TV Box. Either use the new feature of the quick menu (in software versions from August2021 using the green button) or go to Settings / Sounds / Digital sounds to set automatic passthrough detection mode to ON. You may need to experiment with the settings for a while to find a mode that is appropriate for your system.
