Question about Panasonic SC-HT920 System

1 Answer

Does not play multichannel audio (5.1) input through optical digital audio

I have an upscale DVD player, so that I can use the HDMI connection to display upscaled 1080p video from my DVDs to output video to my HDTV. I thought that using the player's digital output to connect it to the Panasonic SC-HT920 digital input would let me have the whole experience of HD video (on the TV) and 5.1 channel audio (through the Pana system), but I was wrong. When I select the 5.1 audio in the DVD an error mesage apear in the front panel of the home theater. If I downgrade the digital output to PCM (instead of bitstream) on the upscale DVD player, everything starts working and I can hear sound, but only stereo (2ch) this time.
Therefore it gave me the hint that it had something to do with the digital audio decoder in the home theater system.
Amazingly, I am able to decode with the SC-HT920 multichannel audio (5.1) that comes from the cable box and see movies that, for example, play on HBO with 5.1 audio.
I have tried every single combination of digital audio settings in the upscale DVD and in the home theater system and nothing made the multichannel audio from the upscale DVD player to be reproduced by the home theater system.
Now I am thinking that there may be some additional layer of protection in the upscale player digital output that prevents the audio being decoded in the SC-HT920.
I am convinced that it should be an internal software issue in the home theater system, that either cannot decode the digital signal that is being input to the unit or prevents the decoding due to some additional layer of protection that is output by the upscale DVD player digital audio output.
If anyone can help me with the solution (or work around) of this problem I will be very thankful

Hi try this.

in the dvd player make sure you just leave it default (bitstream) but in the home theater receiver don't select 5.1 b/c that will only give you a virtual 5.1 not a true 5.1. In fact don't select any sound field at all just select dolby digital or dts depending on the source of the movie then you should be ok.

The only other problem i can see is that hdmi sends both the sound and picture to the tv. You will need to see if there's a function on the dvd player to only send the picture via hdmi and the sound via the optical out of the dvd player.

good luck

Basic DVD player hookup to TV cable diagram. RCA cable (yellow) video and RCA cables (white and red) audio. This is all you need for picture and sound. If your TV only has a single RF input, then you need a RF modulator. RF modulators accept the yellow, white and red cables and output a coaxial cable to the TV single input jack. Usually the TV is tuned to channel 3 or 4 to pickup the RF modulators output.

Alternative connection options are many and include HDMI for HDTVs, component video and for sound, surround sound digital audio connection using optical or coaxial digital audio cable.

Surround sound requires a decoder such as a A/V receiver with Dolby Digital 5.1 or DTS 5.1 or more. 6 speakers connected to the A/V receiver surrounds the listener.

Bluray players will play DVDs and Bluray discs. Bluray gives you High Definition video and typically connects to a HDTV using a HDMI cable.

Just bought a Samsung ht-z320. I used the hdmi

How is the cable box audio connected to the Samsung? That is where the sound comes FROM. HDMI carries signal TO the TV.

The single optical digital input is a limitation if you get HDTV through cable. You probably use it for the DVD.

I found this quote from the manufacturer's propoganda, "deliver the greatest impact from all your digital media". Yeah, all ONE hardware source of it.

You could manually attach the optical output (if it exists) of the Cable Box to optical input on the Samsung for multichannel-audio TV viewing (listening). OR, you could run the RCA L&R analog audio outputs out of the Cable Box into one of the Aux Inputs, but no actual surround will be produced.

How do i use it so my tv programming is in surround sound?

if the Comcast cable box has an HDMI output, it should connect directly to one of the TV HDMI inputs. Then connect the LG DVD unit HDMI output to the second HDMI input of the TV. Use two HDMI cables. Do not buy the expensive Monster HDMI cables. If you have already done so, I recommend you take it back for a refund, then buy the low cost HDMI cables which will work just as good and then you can bank the savings toward a new Porsche Boxter!! Now we have the video connected from both the cable box and the LG system.

Now--what do you do if the cable box does not have an HDMI output--just use its component output and your component cable (red, blue and green) to connect to the TV component input. This will still get the video to the TV and good HD pictures. Hum--do you have an HD cable box? You did not say and I just assumed that you did since you got the HDTV. If not, let me know with a follow up question and I will assist in that area further.

Now for the audio connections--The DVD player will not need any connections since it in the LG unit. The sound will come out the speakers when you start playing the DVD. The cable box is where we get the TV audio to feed the LG unit. If the cable box has an optical output, use an optical cable (again the low cost one)and connect to the optical input on the LG.
This will get the TV audio to the surround system. If no optical output, use the red and white (left/right) audio connections and connect to one of the two the LG audio inputs. To hear TV audio on the LG speakers, just switch to that input or the input associated with the optical input.

To watch DVDs, switch the TV to the HDMI input to which you connected the LG unit. For TV, go to the other HDMI input (or component input).
Switch the LG to the audio input to which you connected the cable box to get TV sound.

Hope this gives you food for thought. If so, and you have more questions, just come back in with a follow up.

Pretty much the same problem

I have the same system. I have a Lifestyle and a Sony TV with a Samsung Blueray player. I also have an X-box 360, plus my pc with all my CDs (I-tunes) plays through my bose. Do this:

1. Use the optical cable for the blueray player to the Bose (AUX).
2. Use a digital audio cable from the cable box (either black or orange output) to the Bose CBL-SAT digital input. (it's a single audio cable)
3. For my PC, I'm using a digital cable from the pc to the Bose. I'm using the TV output because it's empty.
4. For my x-box (which I'm not too happy about) I'm using regular red-white audio cables from Bose TV input directly to the TV audio out. (You can play all of the above through this channel, but don't).

I figured the most important high quality sound should come from the blueray player and from watching regular cable tv. For picture, you should be using all HDMI connections.

Hope this helps.

Samsung ht-z310 home theatre audio problem


I submitted an earlier request trying to determine why surround sound wasn't coming through all speakers when playing my TV.

Looking further into the Samsung site I found out that you MUST connect the optical cable from the home theater unit to the CABLE BOX and not to your TV to get surround sound...I'm currently in the office but will change the connection once home...try connecting to your CABLE BOX instead of your TV and it should resolve the problem.

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.

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.
