I just bought a new DVD player and it came with only a Coax Digital Output. I went and bought a cable for it and plugged it in to my Onkyo HT-R510 and now when I watch movies I cannot get 6 channel sound (no Dolby Digital EX). I have made sure the output on the DVD player is correct and switched the digital input on my reciever. Somebody please help!!!!!
I am not familiar with the setup controls for the 510, but I have a 601 and the inputs must be setup. On my 601, you have to set input preferences, and if I remember correctly the default for DVD was optical. I would try changing the input to coax and see if that takes care of it.
