Can't seem to get surround sound with my Sony STR-DG510 AV receiver to work through a Comcast RNG150 HD cable box to my Samsung UN55F6300 Snmart tv. Can anyone help!

That's because tha hdmi is desing to play sound to the reciver you may have to use out put sound from the unit.

cant use both hdmi and opti outs try sum setting in blue ray but u nee dto plug all blue ray dish directto samsung hdmi then 1 master digital out form tv to sterio digital i n ok tell samsung your output also

The best audio for any source will always come digitally from the first device in which it appears. The Cable Box would be that device.

What preceded this? Was it working and then stopped or did it never work?

Hold down I/O for 5 seconds (("PUSH" and "ENTER" apear on the display alternately)

Press MEMORY/ENTER. After "CLEARING" apperas on the display for a while, "CLEARED" appears.

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.

1. Connect cable to cable HD DVR box, connect video out of cable box to Sony receiver TV video in, connect audio L and R out of cable box to Sony receiver TV audio in and connect TV out of receiver to video in of Panasonic projector 2. Connect Audio and Video out of DVD player respectively to DVD in of receiver. Good Luck :)

I think you have to run a separate audio line from the dvd to the 510, because the HDMI is only passive

I called sony, even though the manuel shows that you can use a component wire to hook up the set top box and hdmi for the tv and dvd sony claims that you can not do this. The cable box must also be wired with an hdmi cable going into the video 2 port.sony claims it doesn't work using component and hdmi together because the receiver is unable to up convert. I hope this helps. I have not tried it yet (i'm at work) we'll see what happens when i get home.

check the volume output from your components, and make sure they are not set too low

Why dvd sound does not play on sony str-dg510?
