Oh well, the sound still lags the video but not as much I think after fiirmware update. If I use HDMI 2 the sync is in time, but then the HDMI 1 outlet is recommended for best video or does it even matter? I can't say I see a difference, but didn't really try to compare. To explain again, this lip sync issue only happens when using HDMI 1 to tv and analog audio out to audio system.
Just switched the TV connection back to HDMI 1 and the lip sync is in time now, hopfully it fixed itself for good.
