Help! \nI've got a Yamaha receiver, Ps4, 5.1 sound and a big arse TV. \nGaming Ps4 - no sound issues\nNetflix via Ps4 - no sound issues\nBluray via Ps4 - no end of sound issues!!! Lipsync problems galore. Now, I know it could be the receiver, it could be the TV.... But, I've made all the adjustment I can think of,... And it doesn't work. In addition, the lipsync seems inconsistent. I think I've fixed it in one scene only for it to be awful 5 mins later. \nA pal said try using an optical connection,.. But I can't see how that can help. If the hdmi is working fine for Netflix... But then again, what do I know. Hence I'm here!
