I have a Denon 1602 amp and Sky HD box connected with an optical lead with sound output set to Dolby D in the sound settings options of the sky box. The sound however drops out every second even though the amp displays it is receiving a dolby D signal. It works fine if I set the sky sound to normal but obviously this is then only pro logic.The amp works fine with the same lead using a DVD player and so is not faulty. Sky tells me it may be a conflict that happens somtimes with denon amps and only solution maybe to buy a new amp! Reading other forums it appears that it's quite a common problem and also affects other makes too (Yamaha and Onkyo) and is down to the fact Sky transmit a kind of pseudo dolby D signal to save bandwidth.If I do buy a new amp what guarantee is there that this will work? Can anyone help?
