Sounds like listening to a robot when watching anything. And the timing is out when there speaking

[Emma+Fannon]

Very hard to understand what there saying at times

Have you tried powering down your Stream box?

If not , just power the box down at the plug for a few minutes and then reboot it.

A simple action which can resolve many problems

@Emma+Fannon In addition to the reboot suggested by @paulg78 you could also try changing your audio settings to PCM or passthrough.  This might help with the lip sync but not sure about the Robot sound.

I've had this on one of my stream boxes and another user suggested changing the sound output to Dolby Digital Plus which I did and so far has fixed the issue. Try changing to this @Emma+Fannon and see if it resolves it. At least for the robot sound anyway. 

[Emma+Fannon]

Yes I have done that it's just the same

Hi @Emma+Fannon  Do you have another TV you can plug your puck into to see if you get the same sound issue? 

If you don't have another TV or if you do and you get the same problem I would phone Sky and discuss some other troubleshooting and maybe puck replacement.
