No Audio I have DirecTV and a Sony BDP-300 Blu-ray Player connected to the receiver. I get surround sound from the satellite receiver, but none from the Blu-Ray player. Both are connected with HDMI and optical audio cables. I get pass-thru audio from the Blu-Ray player to the Samsung HDTV.

test the connection see the diagram attached. Clean the contacts and connector with contacts cleaner.
However you can restore in the menu to factory default.and see what happen.

Hi my name is Mike Houston of DISH Network, I see you aretrying to connect your Blu-ray to the surround sound system and you have DISHNetwork. I wanted to get a little more detail about the equipment to betterassist you, I was looking for the model numbers for the Sony and Philipsequipment to look at the configuration as well did you want any of the componentsconnected to the DISH receiver. I will leave you my e-mail to get the componentmodel numbers and will you be connecting it to our DISH equipment.

There are no compatibility issues. In your BluRays HDMI audio settings set the audio out to PCM instead of bit stream.The TV cannot decode digital bit stream audio.

The Sony manual for this receiver is not wrong, it is just a little misleading.
It does in fact use HDMI but ONLY for the HIGH DEFINITION video portion of the signal, as output from the receiver to your television. High Definition Multimedia interface carries both audio and video, however, your receiver is not decoding the high definition AUDIO portion of it and passing it through the HDMI, nor is it passing any form of multichannel audio through HDMI. So you can see why the receiver is no longer available for sale from the Sony website. The HDMI connection on your receiver is redundant unless you are not using a multichannel audio format, in which case you would be using either the TV speakers or connect an additional audio cable from the TV's "audio out" back into the receiver for external speakers.
All that should be done is use the HDMI cable from your blu-ray player connected directly to your TV. That will give you your picture, and possibly a better one since the receiver will no longer be in the signal path.
Then connect either a coaxial or optical cable from the blu ray player to the receiver for your audio. You will then be able to have Dolby Digital and DTS surround formats.
Your service person was wrong.

Yes, you can connect the HDMI Cable from the Blu-ray Player to the TV directly and then, connect the Digital Optical cable from the Blu-ray Player to the Receiver.

Hello, it sounds to me like the receiver doesn't support the sound format being sent from the blu-ray player. This is because the blu-ray disc would have HD encoded sound such as DTS HD Master Audio or Dolby True HD. Most receivers have not been fitted with these sound formats untill quite recently. The reason for the menu sound playing correctly would be for the PCM (Pulse-code Modulation) which sends simple two channel digital sound supported by all digital receivers. It may be possible to use Dolby Pro Logic or similar formats to give a surround feel, but the only way to get true surround sound in this way would be decode the sound externally and input it through several phono cables into the multichannel input, however blu-ray sound comes in 7.1 so the receiver would need to be able to accept this to get the full effect. If it is possible, see if the blu-ray player will allow downsampling to a surround sound format that your receiver can accept such as Dolby Digital or DTS. Hope this helps.

I am not sure about the Sony BDP-S300 Blu-Ray Disc Player: But the Samsung BD-P1000 Blu-Ray Disc Player requires HDMI cable
to give the best resolution (1080p) possible that the TV set is able
to support. Hope this helps.

you need to go into the settings on the bluray player and go into the audio settings and change the sound output to dts

Thats because if you look in the owner's manual, it declares the fact that it will only broadcast sound from hdmi to monitor not speakers. For sound out of speakers need to connect additional audio cable.
