How do I hook up my AV receiver using the Time Warner Cable adapter?

[Minxie]

I needed to get the Time Warner Cable digital adapter today whereas previously I had a DVR box. My Pioneer receiver was hooked through the DVR box, but now I do not have that and cannot get the sound from my TV though my receiver! ugh! I've tried everything I know to hook it up but can't seem to get it to work.
Here is the back of the receiver and tv... remember that I have to use the adapter as well in this hook up.
Thank you!

Your TV has an optical output and your receiver has optical input. That is what I would use.
