HomePod Stereo Pair Audio Syncing Issue with DirecTV Streaming Box
I have a 3rd gen AppleTV 4K, 2nd gen HomePod (stereo paired) and a DirecTV straming box (Osprey). I have my ATV run via ARC to my OLED LG ARC's input. Everything is fine in this HDMI input. I recently switched away from YouTubeTV to DirecTV streaming. Rather than going via the DirecTV app, I purchased an Osprey streaming box and hardwired it. I am running this via a different HDMI input and using my HomePod stereo pair as the default audio for all inputs. Everything there is also working fine.
- NOTE - ATV, HomePods and DTV Osprey box are all updated with the latest software.
Here is where the issue is... When using the DirecTV streaming box, there is a very noticeable audio/video sync issue when I have the 5.1 setting enabled within the DTV streaming box. When I turn off the 5.1 settings and go strictly to stereo, the sync issue is better, but still not 100% correct.
If I bypass the HomePods as audio and just go strictly with the TV speakers, then the audio syncs up fine as I would expect. It is only when I introduce the DTV streaming box does the sync issue arise. I am not seeing this issue in other rooms with the same streaming box and a different audio source (soundbar or TV speakers), so that leads me to believe that the issue is with the compatibility between the streaming box and the HomePods.
Has anyone else seen an issue like this? And if so, how were you able to correct it? Not sure what other settings changes I can do in order to get this sync issue correct.
