I have followed several pieces of advice kindly provided by forum members but none of them have solved the sound problems on my Sony sound bar. Synchronisation is poor despite trying every permutation of optic cables and HDMI leads. Then periodically the sound stops completely. Dolby on or off seems to make no difference. There are sync options on my Sony Tv and the updated 360 software but they only work for minutes before failing. Can we expect a software update to cure this problem?
