Optical audio not working

Just bought a panasonic 42 plasma and a pioneer 8.1 surround system. using optical cable and setting imput on amp to digital has no sound but if i use rca's and switch to anolog input on amp settings i have full sound. I'd prefer to use optical cable for sound quality. checked all settings and everything seem's correct. thanks

    Same problem!!!!

  • mm46225 Jan 20, 2008

    I have the same problem on my 1706. None of the digital inputs work coax or optical. to troubleshoot, I successfully reset the microprocessor but received the following error on the "Automatic setup" - "Caution:SP None" . There is no test tone.

    All of the these features did work at one time & suddenly stopped.

    same problem too no solution?

  • bouch1 Aug 25, 2008

    I have recently tried to connect my PS3 to my Denon AVR-2803 via optical cable. No sound! I carefully set the PS3 audio setting to OPTICAL and set my Denon source (v.aux) to OPTICAL 1. There is no "digital" display on the the Denon...just "analog". When plugging the RCAs into the Denon everythings works fine. However, I was looking forward to the best possible sound via the optical cable.

    I've been having the same problem, except I'm using a PS3.  I have the PS3 audio set up for the optical audio out.  I switch the input on the receiver to optical and after a few seconds the display switches to (unlock).  I'm thinking that the optical is locked. If so how do I unlock it?  I've searched the manual for something about unlocking anything and no luck.  Any help?

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!

SOURCE: Lost 3.2.1 surround function when I hooked up new plasma

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.

LG sound bar connected to Pioneer TV by optical cable not working

1. if you have something else that you can test the optical wire on. do that first. dvd player etc... if the test item works, it's the sound bar (or a setting in the sound bar.)

2. check the audio settings on your t.v. make sure it's set to output to optical.

3. replace the wire.

if none of these solve the problem, the t.v.'s optical output may be bad.

How to connect a panasonic tcp50gt25 tv audio out (opictal) to a pioneer amp.with opitcal. i connect the cable but no sound,any idea for setting,i did the setting for optical on the amp but still no sound

What is the source? if you are using an HDMI connection from an HD source you should have digital audio. also, if you are connecting digital cable directly to the TV it will send digital audio out as well. check the optical cable at the amp end to see if it is working. it should glow red at the tip if it is.
there are digital input mode settings as well on some receivers. if it is set to DTS it won't work on PCM audio. if it is set to auto Digital it should work on any standard. check the PCM or DTS options in both the TV, and receiver if those settings are there.

1 Answer bought a surround sound set up, which audio output port do i use on the tv cos neither seem to work

This model has two audio outputs. The Monitor out has Video + L and R - L & R are normal stereo and should carry any surround info.
The single RCA Digital audio out must connect to a COAXIAL digital input on the amp.

I have a LG plasma, do i need a optical digital audio out cord to use surround sound?

In order to get true 5.1 surround sound you need to use either digital optical (fiber optic) cord or digital coax cord(RCA style ends) to link between your TV and your digital source such as DVD,digital cable box,digital satelitte receiver.You can route the audio through the TV but that's not the best way to go,I recommend going directly from the digital source to your surround sound receiver for optimum sound. Good luck !

Panasonic SC450 Install

Yes You need a cable that runs from your cable box to the Home Theater System. If it is analog cable then you can use basic Audio Rca Cables from Best Buy. If You have a High Def box I would recommend using a Audio Fiber Optic cable from the box to the surround sound.
