Optical plug I have a Denon AVR-1801. I am trying to hook up a Blue Ray player and can not get the Optical cable to plug into my receiver. It plugs into the blue ray player and a DVD player fine?

Are you selecting the correct video input on the TV that corresponds to the HDMI location? Direct is usually the simplest way to go. Is the HDMI cable okay? Try component video, too.

You need to do digital input assignment. Go to SETUP, DIGITAL INPUT ASSIGNMENT, set OPTICAL 1 for your input (DVD).

Use the mp3 ( line out, audio out), probably a mini plug 1/8th" and get a plug adapter to the standard RCA audio jacks, this is a splitter ( ie. 1 in 2 out ) and go into one of the denon audio in, there are 7 , this is unless you have a digital out on your mp3 player, then use this connection into the denon, 2 optical, and one coaxial which is not common on mp3 players, my bet it to use the digital optical for best quality, but this is possible only if your mp3 unit has that option.

If Denon blu ray has coaxial or optical out for audio, then your Denon receiver will process this signal and will give you 7.1 out sound.

The Denon does not down scale you can not plug a DVD or other device in to the Denon using HDMI and have it come out Component, if your projector only has Component video inputs you must use Component video connections from the DVD and Cable box to the Denon

If your TV has an HDMI input, hook up the PS3 w/an HDMI cable to the TV. This will give you a high def picture (set up the PS3 to output the max resolution your TV displays). That will take care of the video side.

Next hook up an optical cable from the PS3 to the receiver. In the PS3 menu, you have to change the audio settings to output the sound via the optical cable.

Finally to get sound out of the receiver to the speakers, you have to setup the receiver source input. For example if you setup the PS3 to play thru "VCR" input, then you have to make sure the VCR input is setup to use either optical 1 or optical 2 for sound (whichever one you have the optical cable plugged in from the PS3).

• I found this solution on a different site... it worked for me. I needed to change the sound settings in my ps3 to optical... then i selected dolby 5.1.... that took care of my sound.
  

Do you have your TV hooked up, so you can see the AVR-4800 system menu on its screen (if not, see the manual). You need to go down to the digital input menu item where you associate each component with its input source, whether it is coax, optical 1, optical 2, ..., etc.

Yes select audio optical out on your Blu Ray Player under Audio settings and make sure the Denon is set to Optical or Auto in. You should be set to go
