Some TV's and hi-fi have the abilty to switch off the sound at optical links. Check all your settings.

Cut and paste this link. Amazon's page has a link to the JVC manual. That'll tell you what you need to know

On the rear of the receiver you will notice several AUDIO IN connections. Make sure that the AUDIO IN and the receiver's input selector match (for example, if you are connected to AUDIO IN for the VCR section, the input selector on the FRONT of the receiver should also be VCR). Also, make sure that the input selector you are using is set to "Digital Audio" or a digital audio enabled equivalent and NOT analog. Check all connections again to make sure you have not grounded any speaker wire. Check to see if "MUTE" is on TV or Receiver. Try another audio in source just to make sure the speakers are connected properly. If that works, you can pretty much decide that it's either the input selection is wrong or the audio source is not set to digital 9also check to see if PCM is enabled and try setting to "AUTO" if you have that function. If you have option on receiver for speakers A and B, make sure selection matches your wiring.

If you have not run the set up you will need to, however I'm guessing you did because you would have had to make some changes to the settings to get the image to come up on the screen but without being physically at your location I can just guess.
In order to view your PS3 in full 1080p you need the HDMI cable which you already have. If you have not gone into your video settings then you are not viewing via the HDMI cable and you will need to to get things working right.
In order to view via the HDMI cable you would have had to had both the standard PS3 interface cable that comes in the box (the one that goes from the PS3 to your tv with the composite video (yellow) and the left and right audio (red and white) and the HDMI cable pluged into your PS3 and your tv at the same time. then you turn on the PS3 making sure your TV was set to whatever imput the composite and left/right audio is pluged into (typically VIDEO 1,2,3 ect.) and enter the menu, go to the settings and then down to your display settings and change it to HDMI, the image should then leave the screen (because it switched to HDMI) you will need to have your TV remote handy for this because you will need to switch sources on your tv to HDMI 1,2,3 ect, which ever one you have it pluged into. When you have switched to the right HDMI imput there should be an on the screen that is counting down and asking you if you want to accept the changes. Select yes and Move on through the settings selecting the maximum resolution your tv is capeable of
720, 1080i, 1080p) which can be found on the box the tv came in or somewhere on the tv or manual. While running this settings change it should ask you the audio source you are using make sure you select Digital Optical and that it is pluged in to you PS3 and your reciever. Once this is all done you can remeove the standard PS3 hook up that came with the box and put it away you wont need it any more, unless you move the PS3 around and the tv you move it to does not have HDMI in which case you will have to change the settings before you move it back to the standard cable or you will not be able to see it displayed on the tv sceen you move to and it will be impossible to run the settings.
If you have already done that and just want to verify that your source for audio originating from the PS3 is digital optical you can check that in the same settings menu under audio settings. Then make sure the reciver is on and set to whatever imput you have the cable pluged into and you should be good to go.
If all that I have described has been done already then the audio cable could be bad or the problem lies internaly with the PS3 or the reciever.
Good Luck hope this helps
SOURCE: getting stereo speakers to work with flat panel tv
if you hook the low-level audio-out from the tv to an input to the stereo unit, whatever you play on tv will send audio to surround/stereo reciever unit. look on back of tv for red &white AUDIO OUTPUT terminals. plug red/white audio cables from tv to the back of your stereo & plug into audio input of an open source on stereo (tv/video,aux. in,etc.) good luck!
SOURCE: no sound from xbox to stereo using an optical out from TV to amp
If Im reading this right what you need to do
is hook the audio from the xbox to the stereo system
not to the tv .
