My Sony DE 945 Blue LED light indicating digital audio reception
The Blue LED no longer lights and the AFD decode feature no longer works. I still have the DVD player and the HD Sat receiver connected via Fiber Optic "Monster" cables and the sound works, but the auto decoding feature no longer works. Any ideas?

Multi Channel Decoding will only work when you have it briamp.Meaning to have a sepperate power amp hooked up to it for your fronts,Rears end Centre, Speakers, Witch sony is to stupid to tell you that in there owners (Manaul)
what audio cable type are you using, if its digital, you might have to assign that digital audio input with the video signal? go back over your cabling, and make sure the audio is not going to the wrong input and also check that SP/DIF (coxial or toslink) is enabled on the setup menu for the blue ray player and satilite, they normally disable it by default to save a little bit of power, also on a yamaha receveir should have a indication light that lights when a signal/decoding is in action, refer to your documention and trouble shooting section of the manual, hope this helps
OK, so with more troubleshooting, I was able to eliminate the problem with my DE925. It was actually the Vizio HDTV that was causing the problem, as I decided to route the optical audio from my DVD and PS3 directly to the same TOSLINK port on the DE925 and auto-decode worked. It was not the fiber-op cables either. This HDTV was a less-expensive 720p 32" model anyway, so I am not too concerned with the optical out working on it as I can run up to four TOSLINK connections in to the receiver.
If you are playing media that has both dolby digital audio and dts audio, your player and your receiver will decode the first audio codec listed first by default unless you select it otherwise yourself. If your remote or receiver has an A.F.D. (auto format decode) button, press it until your display shows that the sound source is dolby digital or DTS, whichever sound mode it was you wanted when you started your DVD.
Check if you're using the digital cables like optical cable to get the audio from the receiver. If yes, please select the Input mode to AUTO by pressing the mode button repeatedly. If you're using a analog cables, please try to change the sound field and check. Press the A.F.D button repeatedly to change the sound field and try. You can also try connecting a different audio source like Cable box, dvd player and check the issue.
If the issue persists, please reset the receiver. To reset the Receiver, turn OFF the unit and press n hold the MODE + button and Power button till S.F Initialize appears. If the issue still persists, you may be having 90 days warranty after the date of repair or original warranty which ever is longer. Contact sony to resolve the issue.
3.2 IS the "5.1" mode for this receiver. 3.2 is indicating that you have 3 front channels and 2 rear channels. The ".1" is applied to all the speakers (LFE). If you read the manual on page 37, you'll see that "3.2" is displayed with either "Dolby Digital 3.2" or "DTS 3.2". The little icons of the speakers in the display window will show you which channels are active. The bottom line is as long as you see the blue light, it's decoding multi-channel discreet surround sound (at least 5.1).
its for digital decoding of the sound source. You need to connect a digital cable (ie optical) from the DVD player to the optical input in the receiver. The receiver should then decode the source into multichannel components ie 5 channels for example
go in blue ray dvd menu as dvd is playing and select the audio out formatt u wann use has to be on 6.1 or least 5.1 digital not 2.o ch ok and u may be seding the digital with the hdmi outs not both be hard for it to do doe syour tv had digital opti out run that to reivciver on digital input ok tell blue ray options menu also digital oput bitrate ok
Try setting your amp to "auto format decode".
It should easily be heard in this mode.
The sub will not show up on the display when in 5.1 mode. (Blue light on)
Use this with music, and use the 5.1 with movies to get a better experience from your amp.
The sub will work in 5.1 but doesn't show up in the display. Try movies with loud sounds.
Most of the pre-set sound fields are of no use to me. I only use normal surround, and AFD and love it. I hope this works for you!
