Sony KD 55 A85BU Lip sync, Netflix sound and Disney subtitle bugs

[mattscholes]

I have a KD55A85BU TV with a Sonos beam connected via ARC. For the most part is great, BUT …

Lip sync is intermittently appalling, for some reason it is worse on news programmes, eg C4 news. Both using TV or YouView TV.

Netflix will often start up and when you play a show it will have no sound. If you rewind and press play again the sound returns.

Disney channel always starts us with subtitles. You have to turn them off everytime.

For a £1600 TV it's pretty shoddy. Any way to fix these problems?

Thanks, this is what I have already done, two days ago.

I really am at the end of my tether with this TV. Now airplay has no sound when playing from an iPad. Tried two different iPads, using the sound bar and built in speakers. Stunned Sony think this amount of bugs is acceptable.
