Hi I bought the Momo bird 8 just over a month ago and it's been great. Now I have come across a problem. I had the tablet plugged into the tv and was watching the BBCi Player on the big screen. Everything was ok, a bit later I wanted to watch some Youtube videos on the tv and while I got a picture there was absolutely no sound. I've tried it back on BBCi and stored videos on the internal drive but no joy, still no sound. Could it be the HDMI lead or an internal application. Any help would be much appreciated.
