My Sony A80CL-77 is set up with an ARC and two ERA300s. The sound has been great when I stream through apps on the Apple TV, play a blu-ray, or just watch television. Yesterday, I tried watching one of the movies to stream through the Bravia Core (they give credits for movies when you buy a new TV), and the sound was off by about a second. I tried a second movie with the same result.
The weird thing was that when I messed with the settings or returned to viewing, it always synced for about ten seconds and then would sort of skip and then be out of sync again. My wifi connection is very fast, and as I mentioned above, I’ve had no issues with any other streaming, even just through the tv and not the Apple TV.
Any suggestions?
