Hi I’ve got the new Sonos arc and it’s connected to my Samsung Q90R tv via the arc HDMI, my TV viewing is with Sky Q 2tb box. I’m getting lip sync issues being slightly out, I have adjusted the audio settings to zero on my sky box TV and Sonos app but still no joy. I had the playbar before with no problems any help pleased.

Hi All,

I had massive issues with Lip sync and they now seem to be solved.

My Setup  is  a Sonos Arc plugged into the E-ARC HDMI port on a Samsung QE85Q70T. I also have a NVidia Shield Pro running Plex plugged into the TV via a HDMI port.

My Audio sync issues were much more prominent on the Netflix and Plex on the Nvidia shield.

 

My fix was as follows:

  1. On the Samsung TV go to TV > Setting > Sound > Expert Settings
  2. Digital Output Audio for…. option was set to “Auto”. I changed it to “Pass-Through”
  3. Digiti Outut Audio Delay was set at 100. I changed it to 0

 

My issues now seems to be resolved including for True HD 7.1 Atmos Blueray rips on Plex.

. 

Hope this helps someone.

Thank you! We switched our projector to a Samsung one and suddenly started getting lip sync issues with the Arc. Your Samsung TV settings worked perfectly for our projector too. Thank you!
