Setup with: Apple TV & LG TV

Hi, I'd love advice on the best audio setup for my home theater. It consists of:

- Apple TV 4K
- LG C8 TV
- Sonos Playbar + Sonos PLAY:5 for rear surrounds

Questions I had:

1. For the Apple TV, is "Dolby Digital 5.1" the right setting for Audio Format? I thought it should be "Auto / Dolby Atmos," but that results in the TV outputting just stereo to the Playbar.

2. For some reason, the LG Smart TV YouTube TV app outputs Dolby Digital 2.0, and the ATV 4K YouTube TV app outputs Stereo. Any idea why this would be happening? Are there other differences in audio format between LG and Apple TV apps?

Thanks!

    1) Yes. Dolby Digital is the correct setting.
    2) I believe that all YouTube content is in stereo. The two different apps may translate into either PCM or Dolby Digital 2.0.
    3) I would recommend checking with LG.
