No digital input from optical cables

I have a Denon AVR 2105 reciever. I recieve no recognition of recieving digital input from any device -Blu ray 300,sat box or TV. I do get digital from a digital coax. I am using HDMI connection from the BR to TV, component video from the sat box. I would like to use the optical straight into the reciever for sound. Presently, sound is routed back from the TV to the reciever with audio fixed output. I have tried ever combination of settings on the output of the blu ray. I keep seeing bitstream settings from other postings, but there is no bitstream setting in my menu. Help?

Re: No digital input from optical cables

For optical, did you assign the optical input of the receiver, to whatever you were plugging into it? Your manual will tell you how, if you don't know. Also make sure the receiver is set to "auto detect".

Don't know about the Blu ray player......
Good luck!

Re: No digital input from optical cables

Like Ed said, you need to assign the digital input to the appropriate setting on your receiver.

And you can't connect your BR player to your TV via HDMI and then your TV to the receiver via optical and expect to get any sound. There are no TV's that pass through digital audio. The optical output on your TV is for Dolby Digital sound when watching a program using your TV's internal digital tuner (either QAM or ATSC).

Re: No digital input from optical cables

For this to work, you need to route the audio from the reciver to the TV, not from the TV to the receiver, since the TV is the end of the chain; not an intermediate device (if your receiver has HDMI). By doing this, the BD player should not need optical to the receiver. If your receiver doesn't have HDMI, then you have a different issue, but still should have the audio from the devices going to the receiver directly, whether digital or analog.

Re: No digital input from optical cables

With one end of the optical cable plugged into the Blu ray player (while it's on), do you see a red light, at the other end of the cable? Don't shine it directly in your eye! If there's a red light, there's a digital signal trying to go through it. Then it's a matter of the receiver recognizing it.

If you're sure that everything's set right, the receiver may have a problem. Or, if no red light from optical cable, probably a setting in the player somewhere.............
