Samsung QN90B & Beam Gen 1

Hello All! 

I am looking for the best possible audio settings based on my Samsung QN90B, Apple TV 4k 3rd Gen and my Sonos Beam Gen 1. I am using the HDMI to connect the Beam to my TV. 


  1. What setting should I select under my Apple TV Audio Format? Change Format > Off OR On with Dolby Digital 5.1 as the new format? 
  2. Samsung TV settings - if I select change format on within the Apple TV settings, I get three options under the Samsung TV digital output audio format: PCM, Auto or Pass-Through. if I leave change format off within the Apple TV settings, I only get Auto or PCM. 

Overall, what do you think would be the best settings recommendation for my set up? Note that when I select Dolby digital 5.1 with an Apple TV I feel like I’m getting some lip sync issue. Is that normal? 

Thank you in advance for the help!

On the Apple TV, set Change Format to On and the New Format to Dolby Digital 5.1.

Use these TV settings:

HDMI-eARC Mode: Auto or Off (try both settings)

Digital Output Audio Format: Pass-Through
