I have just bought a new Sony KD49XE8005 tv. I already have a Onkyo TX-NR535 and Sky Q. 2 TB box. I have a KEF soundbar with two rear speakers connected to the Onkyo. My previous older TV was set up for me so I am really naive when it comes to all this. The setup seems to work more by luck than knowledge, however. There are two issues. Firstly, I am totally confused about what HDMI cable to put where to get the best out of the system and secondly there are awful lipsync problems when the Onkyo is on. When we turn it off and just uuse the tv speakers the lipsync is fine. Any advice very greatly appreciated.
