Detailed description：
I have recently bought the above laptop and like to use it to watch programmes/movies, but I have a delay between the picture and the sound coming through (whether on the main laptop speakers or with bluetooth headphones - have tried 2 lots of headphones). Have tried to do a few things that were mentioned in various help videos, but none have really helped the problem. Any ideas?
Many thanks!
