Thanks for the response. I'll have to do some reading to understand your advice on connections, etc. I did see that the TV has audio format of PCM or Dolby Digital.
The old receiver puts out great stereo sound, which I'm after, connected to KEF speakers, and connected to Spotify via PC earphone jack to CD inputs on receiver. Also, can get TV sound to receiver via connection from Uverse box audio out to audio in LD jacks on receiver. Just need to solve getting Blu-ray audio to receiver. I had hopes that a connection could be made from digital audio out of the Blu-ray to some type of input on the receiver rather than go through the TV.
I'm sure that my neophyte is showing right now.
In the end I may have to go the new receiver route; although I have little interest in 5.1, 3D, etc.
