Thank you.
I know that I can adjust a/v-sync in there and even set a standard for all videos.
However I don't really like fighting symptoms instead of root causes...
If my much much slower RPi2 offers perfect a/v-sync in the same device chain (Kodi box -> Onkyo TX-NR818 (video set to passthrough) -> LG 65B6V) - why not the S905X?
There must be a reason for this...
I also think that regular DD is less off than the other audio track types, which would make a global offset annoying.
