Try going into settings and turning AV sync to either on or off. That fixed it for me.
I have experienced that on all TVs lately. I think it may be a broadcasting issue, not sure though. There is a sync option you can play with. I actually am returning my 900h and getting the 950. Not happy with the 900h.
I have messed with every AV sync and audio output type all morning.Some settings work for Netflix, some work better for Hulu, and some just suck all together. Pulling my hair out trying to figure out why something so simple is such a pain. I don’t really want to have to edit audio settings every time I watch something different.
Im starting to wonder if my only option is to go back to a 2.1 sound bar and accept low quality audio. To be honest, I haven’t felt like I’ve made that big of a step forward from my 8 year old soundbar and tv setup that I was replacing with this $1,500 setup
