Optical Audio Problems

I'm having issues with my optical audio inputs. Sometimes they work, sometimes they don't work at all. Sometimes they cut in and out. I have tried different cables, and all three optical inputs. I have also tried using 2 different devices (PC and PS3). Everything was fine until one day the sound kept cutting in and out for no reason. Analog inputs work just fine. Do you have any suggestions?

Yes, you can switch between Coax and Optical inputs, but not using the remote. Press the button "Input" on your HT-R430

SOURCE: mv 8000 input does not switch from optical to analog

U need to reset your parameters.....Goto the  System button and then  press F5.  This will lead you to where you need to press initialize to reset the parameters.  Don't worry it wont delete any of your sounds etc.  I had the same problems.....u will probably have to do it every-time you turn it back on and off.  I think the cause of this is due to it having a previous expansion on it......

SOURCE: Wireless headphone connection to multiple components?

Cat,    Splitting an optical output is not recommended.  In fact it would require an optical patch bay, which would be overkill. You could use the headphone output on the front of the Denon AVR3805.    Because this output is behind a door it might be a cleaner looking set up to use the optical output on the top left looking at the back of the unit.  Because those two optical outputs are labeled "optical 3 and 4" they are zone outputs, they should work without having to "map" or patch them internally. The outputs here will be controlled independently as zones from the receiver's remote.      The easiest option looks to be the analog "pre output" located in the middle of the back of the receiver.  The left-most two rca jacks you want to use are labeled "front" and are white over red.  This output will work fine.  Control of the volume will be from the headphone unit and not the receiver.

SOURCE: hooking up a sony playstation 3 with digital optical cable

Here's one solution, if you have an audio output from your tv, you can go from the audio output on your tv to the audio input on your receiver that way anything that is playing on your tv for example, playstation 3, dvd player etc. Anything playing on your tv will have audio on your onkyo home theater system. The other thing I would try if you want to hook ps3 directly to receiver is go to your connection settings on your ps3 menu and change your connection method to digital optical cable.

SOURCE: I am not getting the full surround sound options.

On the remote try scrolling through the settings from the DTS button and also make sure you have the correct audio source selected. I switched to the optical cable but, then found that the better sound for my room came from the RCA set-up.
Good Luck and I hope this helps.

I have an LG TV with an LG HOME CINEMA SYSTEM problem is: watch dvd/blue ray - video fine sound fine (through speakers) watch tv / sky -- video fine sound None throughspeakers on...

There are two things that I can suggest.
1-Test your optical cables to make sure they a good on a known working source because they are very fragile and break very easily.
2-Try to eliminate the use of optical output from tv to receiver. There may be a problem from the HDMI to optical conversion at the tv. Instead, try running the audio directly from the source to the receiver, and let the tv deal with video input only.
Hope this helps,
Good Luck.

NO OPTICAL SOUND I connected HDMI from reciever to TV, HDMI from PS3 to TV, Optical from PS3 to Receiver (PS3 Sound settings switched to Optical, with Dolby Digital 5.1CH, and Dolby DTS 5.1 selected) ...

I think your problem might be at the digital audio setup at the receiver. To fix this, go into the setup under digital audio and make sure that the input that your connected to is set to optical, not analog or coaxial. Example if your plugged into video 1, make sure that the audio setting corresponds to the optical input where your connected. Video 1-optical-1.
Good Luck

KS3102 Digital Optical Input Problem

What I did was turn on the system, don't put in any dvd in, or select an output 1 or 2. Press Menu on the remote, the display on the system display, not on tv should show Speaker, and other options. Select Input, select the one you want to use as the Optical Sound by press enter, then it will ask you on the system display input or optical sound input. Select optical input and press enter it will then say saved. You can then hit exit til goes back to where the display is back on main screen, or just wait til it exit by itself.

Kenwood vrs-6100 receivers optical digital

You want to receive the optical signal from the TV's built in decoder / receiver to play through your Kenwood? Maybe you need to select the digital input. The manual says:

Use the INPUT SELECTOR key (or Input Selector keys)
to select DVD, VIDEO or FRONT AUX.

2 Press the INPUT MODE key.
Each press switches the setting as follows:

1 "F-AUTO": Auto detect
("AUTO DETECT" indicator lights up)

2 "D-MANUAL": Fixed to digital input
("DIGITAL" indicator lights up)

3 "ANALOG": Fixed to analog input *
("AUTO DETECT", "DIGITAL" indicator goes off)

Also check your TV to make sure it is outputting to the optical jack.

Hmm. let me see if I get U correctly. you use u'r theater system with a TV and the audio is fed via optical or U have DVD player that you can feed the audio via optical or coax. I think it is the later, if it is U could be having trouble with sound decoding setting of the DVD player itself. It's like mpeg out or PCM out instead of full DTS or 5.1 dolby digital decoding. If this is the case just use u'r dvd remote and check the audio play back settings. If this does not solve u'r problem, pls state u'r set up briefly, so tht I can understand the type of connection u use. Happy troubleshooting Rifaa
