It works, but there is a delay in the overall sound.

Works, but only with delay (so only suitable for music, but not for video). The more expensive HEOS Bar can do this without delay and be used as a proper 5.1 HomeCinema... would recommend "HEOS Bar" for this.

I have just tried it. In fact, the sound is then delayed on all speakers. With the option 'tv grouping' the bar is synchronous, but unfortunately the wireless is delayed by 40ms so that it sounds like an echo. Too bad. You should have a spdiff setting on the tv that delays the picture. Unfortunately, usually only the sound can be delayed.

So, do you then watch the films or programmes offsync? That would be a complete killer criterion :\
