I have a JVC 8010 receiver. SAmsung TV and samsung Blue Ray hooked via optic digital cables. Sometime it works fine. Other times just doesn't work. Sometimes I can turn things off and randomly hitting buttons, unplugging and replugging things, and eventually it will decide to work, but the next time I turn it on... nothing. Starting to feel like I am on Candid Camera and somebody is hiding in the background pushing buttons to make it work or not work. Any suggestions on what I should be looking for or trying?
I don't know if this helps but, if you have your bluray hooked directly to your tv some times TVs can have issues sending the proper channel to audio out to the receiver. You should always connect your bluray and other devices directly to your receiver.
if that's not the case,
Try turning the tv speakers back on, test the bluray hooked directly to the tv and see if things work flawlessly just with the tv and bluray.
If they don't there may be something just wrong with the cables.
If they do work flawlessly then there may be something wrong with the receiver.
If you already had your bluray connected to the receiver, I would still try direct to tv test and swapping cables.
The randomness leads me to think cables. But you can rule them out by testing directly to TV.
I hope that helps
Thanks for the suggestions. I do have the blue ray and tv connected directly to the receiver with optic cables. Blue Ray is connected to TV with HDMI. TV doesn't have optic input, just output. When it isn't working the receiver can't seem to find the digital signal. TV speakers on TV do work with both tv and blue ray, but I think that is the HDMI connection at work. When it isn't working if I pull the cables off, you do get the red light through the cable on the receiver end from both TV and blue ray - I know it could still be screwed up signal but it seems odd that both devices would not work and/or both optic cables would be randomly bad at same time. I am leaning more and more towards receiver, but keeping hoping for simple (read cheap) fix.

SOURCE: 8' Optical Cable from TV to Receiver and Signal is Breaking Up
Before you buy anything try checking the AUDIO Settings in the Menu of Each Device (Mostly TV) and see if they are set to PCM or BITSTREAM. HDMI is mostly set to PCM while Optical is generally Bitstream. The TV may be set to the opposite of what it needs to be. I would try to get PCM to work first cause it is Better, If not then set what you can to Bitstream and it should pass. Also check in TV Menu for SOUND OUT or AUDIO OUT or SPEAKERS. Some TV's have a problem passing Audio through when they are already Outputting them to it's own Speakers! I Hope this Helps out!

If you would like to use high definition audio decoding, connect the HDMI from the blu ray player to the receiver. If that it not an option for you due to lack of equipment such as an additional HDMI cable to go from the receiver to the television for the video portion of the signal, then connect your optical cable again. After the optical cable is connected, make sure the Dolby Digital decoding is enabled on the receiver, and that the media you are playing also has a version of 5.1 surround sound. Then, enter the setup menu of the player (which I suspect this is actually where the problem might reside in your case) and make sure that Dolby Digital and DTS are not set to "downmix." Dolby Digital should be set to output Dolby Digital and so on and so forth...hope this helped.
Testimonial: "Thank you for the insight. I may have figured this out on my own eventually but this definitely got me situated much much faster. "

If your remote also controls the Cable Box you might want to look at its audio settings. Maybe you muted it.
BTW: it would be a good idea to also run video and analog audio from the cable box directly to the TV if it has speakers so you can watch and listen independent of the Onkyo.

When you say you have sound from the BD prior to disc load... where (TV and/or receiver)? Initial wake-up audio is usually 2-channel.
Describe the optical audio connection input to the receiver and any other audio paths that are attached.
Do you have other multichannel sources you could use to test this, like a cable TV box?
There's an obscure setting in the receiver called PCM Fix (on Page 21). Give that a look.

The TOSLINK optical connector is almost aquare and should be the same on both blue-ray and on the receiver. There are 4 orientation you can try and only one fits. Blue-ray can have the connector installed rotated, but it should be the same connector.

Looking at the cable at Amazon I can see that it is the correct cable. If it really doesn't fit, maybe you have damaged cable or damaged connector. Try the other end of the cable and/or other optical input on the receiver.
BTW there is also combined analog/optical jack connector. It looks like normal jack socket, but accepts also optical signal. But this is not called Toslink and usually is not used in home theatre devices.
