Air play apple TV 4K Sync

[Vegus]

In DOS2 you can only set the latency for the AUX input, so not for Airplay. I have the same issue with getting sync from Apple TV 4K, as this doesn´t have an optical output (or any other physical audio output) . I have tried the Audio sync-feature in TvOS13, but it does not work with the Phantoms.

Hi all, I Have a 4K Projector hooked up to a Apple 4K TV since updating to the new software the audio is rock solid, before when playing audio over airplay in I Tunes the airplay would drop out and had to reset via system preferences not anymore and have binned the dialog literally. Now on to the projector side of things sync first before installing the new software totally in lip sync, I think because my projector had the same latency as the Golds now since the update they are out of sync and drop out frustrating! Ok there is an option on my apple TV to sonically sync the audio to the speaker system but I think this is for flat screen TV's not projectors via my Iphone and in the Dev app I am aware of the low latency high stability feature for the aux input but arrgh...........any advice?

Hi Funky Phantom, in DOS 2 you can change the latency. In Devialet App go to Settings and in Advanced Settings in Av Sync you can change the latency.
By default latency is set to 190ms which is a good setting for generic purpose.
On my setting (4K projector with optical built-in, i've no apple tv), my best lip sync is when setting is between 100 and 120 ms.
Cheers
