Like the subject says, how do you reset the receiver? A friend of mine got one today and he is getting no sound from the digital inputs, only analog inputs give him sound. I went there to check it out and all the connections seem fine. The receiver seems to lock on to the digital signal but there is no sound. Strangely enough, the receiver only works in the "Stereo" mode via the analog input and when you try something like DPL-II or DTS-Neo, no sound again. Any ideas?
