I have known this kind of thing to happen in the past. While attempting to watch one of the movie channels I found that I could get no sound and spoke to reps from Sky who after a long period of talking me through various procedures on the phone decided that it was my viewing card which was at fault and told me to ring back the next day if the fault was still there and they would send me a new card. It was only after going off the phone that i remembered that the A.D. was on and switched it off with the same result as you got when doing so, the sound returned on the channel where it had previously been missing. The only problem then was that i had missed the film, which I watched a few days later. i have to point out that this happened a few years ago well before H.D. was ever thought of.

I found that there was no audio on Channel4 HD. I contacted Sky and an engineer came today. He could not explain the reason, no other HD channels were affected. So, he assumed it must be a fault with the box, and so replaced it. After he had gone, I got an error message to say there was a fault with my viewing card. So, rang them again, with great visual-impairment difficulty,I followed her instructions to remove and replace the card! I re-set my settings, including audio description. Guess what, on going to Channel4 HD again, no audio again! Phoned them yet again, I was a very unhappy and stressed bunny, and thanks to my original report, they agreed that this was a fault which they were previously unaware of! I found when I switched off audio description, yes, I got audio back on Channel4 HD! What a performance! Yes, they thanked me for bringing this to their attention, but there was no compensation for the stress or cost of the many phone calls I had had to make! Reluctantly, finally, she agreed to reduce my next bill by £5! I had suggested £20! I await information on how they proceed with the fault! Thought I ought to let others know! Cheers, off to watch HD apart from Channel 4! Maggie
