This is a problem with these recievers. I found this here
In your STR-DH520's HDMI Settings, set the Passthrough option to OFF or Auto and the Audio Out option to AMP.
If Audio Out is set to Amp+TV, only audio formats that the TV can process are acceptable and may therefore be transmitted from the BD player. Since your TV can't handle HD audio, but by configuration must receive an audio signal it can handle, the BD player is banned from transmitting HD audio, and you get the effect you observe.
