Av sync issue with New onkyo nr636
I got a problem.. Been driving me nuts. I got the oppo 103D. Ps4 and sky box all plugged into the brand spanking new onkyo nr636 and all out of sync when I watch a movie it goes out of sync. Audio a little before video. Tried factory restarts on all devices to no effect.
Not really any clue what it could be down to. But I got onkyo Germany looking at it. A onkyo UK service centre. LG and oppo. Until I can go back and find what mode it is in sync I'm stuck.
So confusing when you have this problem. But my initial thought is its a lip sync bug in the onkyo since changing picture modes doesn't effect it at all.
However the devices do work fine if I plug them directly into the tv and use Arc back to the avr . Strange.
