I have my Sky+ box connected via the toslink to the digital input of my receiver but the only input the receiver recognises is the analog one. I know that there should be a DD 5.1 output on some box office films and I am aware that the box needs to be configured for 'normal' or 'DD' in the service menu but should there be a digital output from the box all of the time? The optical cable is connected to the correct assigned input of the receiver and the receiver is set to automatically detect whether analog or digital signals are being received. On normal viewing, no digital input is flagged and forcing the input to digital results in no signal. Can anyone help?
