Hi, I haven't used my 360 S for a couple of months and turned it on tonight to watch Sky TV. It initially forced me to download a number of updates but after that I thought all was normal. When navigating around the dashboard, I get the little sound effects as I move from menu to menu or click on stuff and if I go into a game the sound is all fine, but as soon as I go into Sky Player or Zune and try to play some video, I lose the sound. Its gone immediately so you don't hear any sound from the video. And then if I exit out of Sky Player or Zune, and start moving around the dashboard again, I no longer get the sound effects as I move from menu to menu.
I've tried going back into the sound options and click on 'Enable sound effects' but that makes no difference.To get the sound back I have to turn the console on/off, but then as soon as I go back into some video, its gone again.
I'm using an HDMI cable to connect to my TV and Sky Player always worked fine.
