No surround sound from my PS3 through the Onkyo 5100. Video OK

I do not own a blue ray player but my son has a PS3. The thick cable is most likely HDMI and it should work without the red/white sound cable...try unplugging them so the auto detect feature if available and activated is not trying to compete by finding 2 sources. If that works great! If not, you can get a yellow RCA for the video and just use those as a source - again, don't use the HDMI cable and try it. If you don't have a yellow RCA, I've used another red or white for video testing to see if I can get a video feed. Most newer red/white cable will pass a video signal just fine and are only color coded for ease of hookup.

No no no!
# 1. You need to connect all your components to your TV via an HDMI cable. For true HD and digital sound this is needed. Your TV (if its an HD TV) should have 3 or 4 HDMI inputs. So your Xbox/PS3 should be connected via HDMI cable. Your HD sat or cable box should also be connected with an HDMI cable. Same for your Blu Ray player.

#2. Now that your components are connect in a way which will enable you to see their media in either 720p, 1080i or 1080p your ready to get the Digital sound to your speakers. On the back of your TV you should (again on most all HD tv's) have a digital audio (optical) out. You need to purchase a digital (optical) audio cable and plug one end into your tv's digital audio out jack. Then plug the other end into your audio receivers digital audio in jack. You may have to go into your receivers menu to select or enable the digital/optical input. Then you should be rocking and rolling with true digital DTS, Pro Logic, Pro Logic 2 in either 5.1 or 7.1...

Think of your TV as the hub. Connect all the components with HDMI cables. And then your TV to your receiver with a digital/optical cable. It's that simple.

Never never use the red and white cables for audio. They were designed for 2 channel stereo sound. They won't deliver 5.1 or 7.1 digital sound.

Also... Don't ever hook up any component using the old "yellow" video cable if you want picture quality better than 480i resolution. They won't do HD period.

Here is a list of the popular video cables and they highest resolution.

Yellow video cables - 480i resolution

S video (super video) cable - 480p

Component video cables (red/blue/green) - up to 720p

HIgh definition multimedia interface HDMI - up to 1080p (full HD) and digital sound.

Hope this helps...

Hi
In this configration you will not get surround sound. Because tv is not able to reproduse the surround sound through its out put from the HDMI input. You have to connect the HDMI of PS3 to the Onkyo receiver and the HDMI Monitor Out of the Onkyo to the TV. This can only done if the Onkyo AVR Have HDMI IN/OUT option.

If not the connect the Optical out of PS3 to any one of the optical input of the Onkyo receiver.
After that you have to goto the setup Menu the Onkyo and assing the optical input in wich you have conncted the PS3.

Aslo the following setting in PS3

Menu>>> Settings >>> Sound Settings >>> Audio Output Settings >>> Select the connector..= DIGITAL OUTPUT (OPTICAL)

Have you seen the user guide?

The TV is intended to be an end point of the video, not a source of audio. Many TV's (monitors) don't have ANY audio, much less surround sound capability. Composite Video is theminimalist video connection for setup; Component video to the TV should suffice for viewing DVD's.

Is your TV the SOURCE of surround sound programming (via an antenna) or does the programming come from elsewhere like a Cable Box? THAT would be the source you need to tap for surround sound.

Direct TV is compatible with all TV's. Just requires the proper cable connections

You need to assign the HDMI input(s) to the functions they represent, using the Front Panel Tuning/Preset control...

If you connect a video component to an HDMI input, you must assign that HDMI Input to an input selector in Setup.
For example, you could assign the “DVD” setting to “IN1”, and assign the
“CBL/SAT” setting to “IN2”.

Likewise if you use digital audio inputs...

Assigning the Digital Input
If there’s no sound, press the [DIGITAL INPUT] button repeatedly until sound is heard. The digital input is now properly assigned.
If you connect your DVD player to the AV receiver’s COAXIAL 1 DIGITAL IN, and your cable/satellite receiver
to the COAXIAL 2 DIGITAL IN, as shown, it’s not necessary
to assign the digital input.

Depending on if your surround system has a hdmi input or not. if it does you can connect the blu-ray player to it. If it doesn't have an hdmi input you will have to run the hdmi cable from the blu-ray to the tv then run a set of rca cables (red and white plugs) from the tv audio out to the surround systems' audio input jacks to get sound through the surround system. Most surround systems don't have an auxiliary input for another video device.

There is no substitute for HDMI. However, the 'digital in' cable connection that you want to use is still digital and will sound almost exactly the same. The differences are barely noticeable to the human ear. Here is a list for you to see the pecking order of each type of connection.

Audio connections from best to least go in this order:
1. HDMI (digital)
2. Fiber optic (digital)
3. Coax - Digital (digital) <--- The one you want to use.
4. Component (analog)
5. RCA/AV (analog)

Video connections from best to least go in this order:
1. HDMI (full HD digital)
2. Component (Blue, green, red, white, red - HD analog)
3. S-Video
4. RCA/AV (Yellow, white, red)

Good luck!!

Your not going to be able to connect in series (not sure if thats your goal) since your limited by the type of connections you can use. Your receiver is going to have to be switched depeneding on what source you want to listen too. DVR, DVD, etc. HDMI is going to important for your TV connection. Radio Shack has cheap HDMI cables.
So... connect HDMI from DVR to HDTV this will give you sound and picture to TV. Connect DVR optical or coaxial ( RCA if you dont care about surround) to Receiver to give you DVR sound thru Receiver input.
Connect DVD to receiver via optical/coaxial/rca for DVD sound thru receiver (again RCA is not recommended for surround).
Connect Component video to HDTV(or HDMI if TV has second HDMI input) to give you video from DVD.
Connect Yellow video or S-video from DVR to DVD recorder input to allow recording from DVR. Also connect red/white audio to (same) DVD input.
That should cover it.
