SOURCE: Connecting DVD player to AV receiver

If you've done that already and still no response from your system, I would suggest to take back to the place where you bought it and ask them to check it for you. Tell them that you follow the user's manual to the "T" but still unable to make it work.
Good Luck.

SOURCE: Playstation 3 audio connection into Yamaha HTR-6040 AV Receiver

Solved problem with Yamaha HTR-6040 AV Receiver. My daughter had inadvertently changed the program to "Direct Stereo" mode which allows sources to bypass the decoders and DSP processors so you can listen to 2-Channel PCM and Analog sources. Nothing to decode digital audio in this setting!

HDMI cables contain both your audio & video in one cable. Remove your optical cable from the box and disable in in the cable box menu and that should fix your problem.

SOURCE: RXV 1500, I am unable to get 5.1 audio

Just got off the phone with Yamaha customer support, who were very helpful.  The display on the amp, in the lower right hand corner, displays the source input, not the output.  So, for example, you can be watching cable tv, and the cable tv is sending a 2-channel stereo signal to your receiver.  Your amp shows only L and R.  But since it has a processing system, depending on the processing program you have chosen it will probably distribute that sound to all five speakers.  You will be confused, because you hear sound from all speakers but you only see L and R lit up.  You will believe that you are not getting 5.1 sound.  And you will be correct: you aren't, because the source is not sending you a five-channel signal.  That's where I got panicked.  So the Yamaha representative said, insert a DVD that you absolutely know contains a Dolby Digital audio.  I inserted Shaolin Soccer DVD, went straight to a scene in the middle, and bingo!  The center and surround right and left speaker lights lit up!  So there is the 5.1 surround sound.  It will light up when it detects that kind of sound from the source.  Otherwise it will probably give you a sort of "fake" 5-channel sound that it creates from a 2-channel source.
Now the question becomes, are your connections getting the 5-channel sound to the amp correctly?  I just confirmed that my DVD, connected with a Coaxial cable to the Yamaha, does get 5.1 surround sound, if the sound is encoded in the DVD.  I have not tested this yet with video games or Blu-Rays; I will post again if and when I confirm that this works on a PS3.

SOURCE: digital optical output for technics 5.1 surround sound receiver

I went to the HDTV plasma manual. It stated the only way the digital optical audio output would work (from this TV) was to go to the menu, select audio and turn off the TV speakers. Basically, it had nothing to do with the technics receiver.

Connect tv to surround sound system

Connect a RCA cable from the TV Audio output (red/white)
to the surround sound Audio Input (red White)

If your TV has a "HDMI OUT" and your Surround System has a
"HDMI Input" Then use a HDMI cable instead.
You will need to set the source on your Surround System to
the audio source you use on the surround system(input)
On most it will be TV or Auxiliary.

I have a 42 in LG HDTV and a dish satellite and a LG surround sound system how to I hook these up to hear sound while watching the sat

See if your satellite receiver has a digital out socket in the back ( optic / coaxial ). If so get yourself an optic/coaxial cable and link the TV out to your LG Home Theaters optic/coaxial In.
Now if your Satellite receiver does not have a digital out for sound you will have to connect the TV's audio out to the LG Home Theater Systems Aux / SAT / CBL input using appropriate cables .Either 3.5mm phono to 2RCA or 2 RCA to 2 RCA cables.

I was using my vsx D510 with a hiteker dvd player

Each digital input is assigned a name and a function by you. You have to dig out the manual and assign the digital inputs.

My $.02. Why do you not want to use the coaxial imputs? There is no functional superiority of one over the other BUT coaxial is a) cheap, since it uses standard RCA cables; b) adaptable, since you can splice or split them among two devices; c) not delicate or prone to failure due to tight bends. I share one coaxial input between two digital device with an RCA splitter cable. Just have to make sure to turn the one I'm not using OFF. Try that with optical.

Pioneer vsx-519 no sound from center and surround

Make sure that the sound field/programme you have selected is dolby digital not stereo.(On the amp)
You also need to check on the display that is says DIGITAL not ANOLOUGE, as only a digital input, Optical fibre cable, HDMI, COAX will be a digital signal.
If you are using red and white rca connectors, it is not going to work, as this is an Anolouge signal.

Sony DG510 - Not Getting surround sound out of Cable

Did you try it on BOTH the SAT and Video 2 optical ports? Still not working? Could be the Optical cable is bad.

Does your Cable Box also have a coaxial digital ouput? It looks just like a standard RCA connector but says Digital somewhere near it. Try one conductor of a standard audio cable from it to the "DVD" coax connector. Select DVD to hear it.

If it still doesn't work jump into the Cable Box setup to make sure it's output is set up properly.

I would recommend using the coaxial digital option if you have it.
1) The cable isn't special or expensive like the optical cable is; a garden-variety RCA cable works just fine.
2) You have virtually unlimited distance to work with in the house.
3) You don't have to be so darned careful with it as with optical.

No sound

you have the co-axial and optical inputs both set to a specific input? ie. For my xbox 360, I use optical. so I set my optical to DVD, and then I have to set the receiver to DVD to get the sound.
