SOURCE: Connect PS3 for playing/viewing blue-ray thru surround sound

I just finished setting up my system last night and was facing similar problems with sound/video from my PS3. The only option I could get working was to have the HDMI cable connected from the PS3 to the TV and then connect the Optical cable to the receiver for sound. I was under the impression that HDMI handles sound and video but for whatever reason the PS3 does not agree.

I have DTS sound and fantastic picture now through my PS3, hope this helps.

Cheers

Hi,
You have connected from PC to TV right???
1.To get the video you have to connect to TV
2.Please take a separate cables for to listen audio and to watch video,
for audio connect cables from DVD Player to Home Theater you can listen the audio
for video please connect the HDMI video to TV Where You can enjoy both.

No,you are not mistaken actually.I really don't have much to offer though.I just want to let you know that I have seen many problems with HDMI cables and no sound.HDMI does in fact transfer audio/video.Even though I do not like to use Wikipedia because anyone can edit the info,I check and see if it is accurate first and does give the best descriptions and is the quickest and easiest to find.This is a newer technology.Any new technology is usually not figured out until about year 5.In year 3,they are able to get the kinks worked out,but year 4 is already in production.They start designing and building the best version for year 5 next.Although 5 years isn't always achieved,it is more of a minimum to see the best possible of the technology.Happens with cars,TV's,VCR's,etc.Prices come down as everyone who wants it is greatly reduced by then also.Anyhow,here is a link to some info about HDMI.Scroll down to Communication channel protocols.Under TMDS there is some relevant info.You may not understand the terminology but basically it seems that there is an internal automatic muting with certain changes in the audio signal.It just sounds to me like the automatic mute is too sensitive right now and will improve over time.There is also some encryption taking place which is basically taking the output,scrambling it,sending it somewhere,and then being unscrambled and reproduced identically.Same as wireless internet.With all the various products being used,everyone has their own way of doing something.Since it isn't exactly made with exact specifications,there are many variations to interpret.If someone were to have ALL components made by 1 company,it would most likely work much better.How many people have that kind of setup though?Very few.There is not 1 company which makes everything they produce,better than everyone else's.Some make better radios,some TV's,etc.Right now,some of the better TV's are Samsung,LG,Vizio.Some better phones are AT&T,Panasonic.Bose has been at the top of the food chain for years for audio for that reason also.They do audio,nothing else,so they can put everything into it.I know this is a bit wordy but that's why I am here.To inform and educate people about things which they most likely don't understand and encourage them to spread the word.Hope you understand this anyhow.Basically,depending on how old your PS3 is,there may be compatibilty issues.With HDMI changing/upgrading rapidly,if your PS3 is an earlier version,it could simply be compatibility because PS3's even were changed as they sold more.If you have any questions or need more help,just comment here and I will get an autolink to your post and reply ASAP.Here is the link for HDMI characteristics/operation.Good luck,Greg

Testimonial: "Thank you for your response. I was able to get audio for my PS3 by connecting an optical cable from the PS3 to the Cinemate interface module."

I found the fix. Had the same problem.
I right clicked on the sound speaker icon in the bottom right of Windows 7.
Chose Playback Devices.
Once this window opens, then make sure you are on the Playback tab.
Scroll down until you see the HDMI Device. (Mine was hidden at the bottom of the list.)
Then choose "set as default".
The sound will begin playing on the TV with only the HDMI connected......no need for an extra audio cable.
