Hope someone can help. I have the receiver hooked up to a Blu-ray player with hdmi (to TV) and optical to receiver. The problem is even though the discs are encoded with dolby digital, I can only get the pro-logic to work. When I press A.F.D., it switches to front left and right speakers only. I currently have front, center, and a sub connected. Ive had this receiver for a while and had it hooked up to a laser disc player years ago, without any problems and the multi channel decoding light always kicked on . Now I cant seem to get it to read the multi-channel format I know the Blu-ray is encoded with. Please help, thanks in advance!!
Check audio output on blu ray. Set to bitstream legacy to properly output dd , dts formats - it may be on PCM or stereo or bitstream hd which your receiver may not decode , defaulting to a PCM stereo input

No no no! # 1. You need to connect all your components to your TV via an HDMI cable. For true HD and digital sound this is needed. Your TV (if its an HD TV) should have 3 or 4 HDMI inputs. So your Xbox/PS3 should be connected via HDMI cable. Your HD sat or cable box should also be connected with an HDMI cable. Same for your Blu Ray player.
#2. Now that your components are connect in a way which will enable you to see their media in either 720p, 1080i or 1080p your ready to get the Digital sound to your speakers. On the back of your TV you should (again on most all HD tv's) have a digital audio (optical) out. You need to purchase a digital (optical) audio cable and plug one end into your tv's digital audio out jack. Then plug the other end into your audio receivers digital audio in jack. You may have to go into your receivers menu to select or enable the digital/optical input. Then you should be rocking and rolling with true digital DTS, Pro Logic, Pro Logic 2 in either 5.1 or 7.1...
Think of your TV as the hub. Connect all the components with HDMI cables. And then your TV to your receiver with a digital/optical cable. It's that simple.
Never never use the red and white cables for audio. They were designed for 2 channel stereo sound. They won't deliver 5.1 or 7.1 digital sound.
Also... Don't ever hook up any component using the old "yellow" video cable if you want picture quality better than 480i resolution. They won't do HD period.
Here is a list of the popular video cables and they highest resolution.
Yellow video cables - 480i resolution
S video (super video) cable - 480p
Component video cables (red/blue/green) - up to 720p
HIgh definition multimedia interface HDMI - up to 1080p (full HD) and digital sound.
Way #1 connect your cable box to your a/v receiver with one hdmi cable. Connect your blu ray player to your a/v receiver with a second hdmi cable. Lastly, connect a third hdmi cable from the a/v receiver to the television. (3 hdmi cables needed this way)
Way #2 connect your cable box to your television with one hdmi cable. Connect your blu ray player to your television with a second hdmi cable. Connect your a/v receiver to your television with a RCA/composite a/v cable or with a fiber optic cable. Connect your cable box to your a/v receiver with a fiber optic cable or RCA/composite a/v cable. Lastly connect your blu ray player to your a/v receiver with a fiber optic or RCA/composite a/v cable. This method takes 2 hdmi cables and three sets of fiber optic and or RCA/composite a/v cables.
Can't get more specific than that without having the a/v receiver's model number, type of cable box, and television model number. Hope this helps.
If you would like to use high definition audio decoding, connect the HDMI from the blu ray player to the receiver. If that it not an option for you due to lack of equipment such as an additional HDMI cable to go from the receiver to the television for the video portion of the signal, then connect your optical cable again. After the optical cable is connected, make sure the Dolby Digital decoding is enabled on the receiver, and that the media you are playing also has a version of 5.1 surround sound. Then, enter the setup menu of the player (which I suspect this is actually where the problem might reside in your case) and make sure that Dolby Digital and DTS are not set to "downmix." Dolby Digital should be set to output Dolby Digital and so on and so forth...hope this helped.
Before you buy anything try checking the AUDIO Settings in the Menu of Each Device (Mostly TV) and see if they are set to PCM or BITSTREAM.
HDMI is mostly set to PCM while Optical is generally Bitstream.
The TV may be set to the opposite of what it needs to be.
I would try to get PCM to work first cause it is Better, If not then set what you can to Bitstream and it should pass.
Also check in TV Menu for SOUND OUT or AUDIO OUT or SPEAKERS.
Some TV's have a problem passing Audio through when they are already Outputting them to it's own Speakers!
I Hope this Helps out!
I was talking with LG on virtually the same problem. I have a samsung blu-ray player hooked up via HDMI. Even though the blu-ray is outputting 5.1, 6.1 or 7.1, the LG is only outputting 2 channel unless you switch to pro logic. LG states that this is a known problem and that you are to return the system to where you bought it for a replacement. Call the 1-800 number and they should give you the same answer.
TV is HD correct? Use the Y/CB/CR from the Sat to the TV. Use the Digital optical cable for sound from the sat to the receiver. Use the s-video from the dvd player to the tv and the l/r to the receiver for sound. I would suggest upgrading to another set of Y/CB/CR cables to connect your dvd to the TV and benefit from better picture. Also, buy another optical cable for dvd sound (so you can enjoy surround sound). Your receiver has two optical inputs so youre covered there.
Is Yamaha HTR-640 a receiver? Try HDMI from PS3 to receiver or Sony HDTV. If HDMI from PS3 to receiver the you need and HDMI from receiver to out Sony HDTV. You could connect everything to receiver and HDMI out to HDTV. You can not have an HDMI cable AND an optical cable coming out of the PS3, only one or the other.
