I have a problem with my macbook pro. I have used it to watch video on my Panasonic tv via the HDMI adapter - both from the net, vlc, Itunes and what not.

But after I came back from holiday the sound is choppy - it will be ok for about 7 seconds and there will be a short pause where it falls out and then back again.

I've checked the cables and output in the settings but I can't find any problems - do you have some suggestions?
