The speaker's lips (video) and his voice is out of synchr if you listen thru bluetooth headphones. This was checked with Sony MX1000 and Optoma projector.
Thank you for advice. I didn't expect to find audio offset in playback rather in audio submenu. It works of course. The fact is that it is needed in a case when spdif/raw is set. I use it for the 5.1 DD/DTS decoder-amplifire and when my wife gets angry I have to switch to BT headphones. There is no problem with synchr if one uses LPCM 2 channel.
