Assistance needed with PS3 audio output involving HDMI and coaxial audio cables
Up to today I had ran all of the audio cables from my various devices directly into my surround sounds system. This led to not only having to change the input on my LCD every time I wanted to use a different device, but also having to change the input channel on my surround sound system. Today I (finally) discovered that I can run all of the audio cables directly into my LCD, pairing each audio cable with it's corresponding video cable and it's respective input on my LCD. Then I could simply run one coaxial audio cable (the only audio output on my LCD) into my surround sound system. I've had success with all of my devices except for one...my PS3.
Prior to making the switch today, I had been running an HDMI cord from my PS3 to my LCD for video, and running an optical audio cable from my PS3 directly into my surround sound system. Now, for all intensive purposes, the research I've done has told me that there's basically no difference in sound quality between coaxial audio and optical audio, so I figured it wouldn't make any different if I eliminated the optical audio cable and just went with the coaxial audio cable along with the rest of my devices. I disconnected the optical audio cable from my PS3 and my surround sound system, and left the HDMI cord connected. I then went into my PS3's sound settings, and made sure to switch from optical audio output to HDMI audio output. I figured the sound would travel through HDMI into my LCD, then out via the coaxial audio cable and into my surround sound system. Well, for some reason it didn't quite work that way. I don't get any sound through my surround sound system when it's on the channel for coaxial audio input like I do with the rest of my devices that are run through my LCD.
Is this normal? Does HDMI override everything else? Am I simply going to have to keep the optical audio connection from my PS3 directly into my surround sound system? I won't mind at all if that's the case. I just didn't know if there was something I was missing and/or doing wrong.
Any insight/assistance would be greatly appreciated.
Thanks!

Unless you have an unusual TV, it's quite likely that you are only getting stereo when using your TV to switch audio sources. The optical/coax outputs are there to provide DD for people who use off air antennas. Most sets only pass 5.1 sound from their own internal tuners. Audio from other input sources such as DVD players, satellite boxes, and game consoles is downmixed to stereo or not passed out the digital port at all.
In my opinion, you really shouldn't use the TV as an audio switcher. Run your audio to the AVR and the video through the AVR or direct to the TV. Then, get a Harmony remote. You can do all of your switching with a single button push. Sometimes I think my Harmony is the best single piece of AV gear I own.

So you're saying that for the best sound quality I should still connect all of the audio inputs directly into my surrounds sound system? Also, I'm currently using a Logitech Harmony 720 universal remote, and like you say, it's fantastic. The only reason I thought routing audio through my LCD would a good idea, was because I thought it would cut down on cables. Now having a couple of extra cables wouldn't bother me at all, if that meant getting the best possible sound that I can.
Thanks again!

I hate to bring an old thread back to life, but my problem seems pretty related to the OPs.
I have a philips 47" 1080p set, the 7422 model. It has 3 HDMI inputs, and a coaxial spdif output. and NO it is not just for outputting the digital sound from the built in OTA hd tuner. We have a denon 6.1 receiever, it is older in today's sense having no HDMI, but does the obvous DD/DTS.
I was surprised that the coaxial output on the TV will passthrough the digital sound from the HDMI source connected to it. So I have my DTV HD box and an HTPC connected to the TV via only HDMI cable. The TV successfully passthrough the digital sound to my receiver via the coax output from the set. I confirm this and my receiver switches to DTS or DD depending on the source audio. VERY NICE I thought to myself.
Enter the PS3. I figure everything will be the same right? And surely it was at first. Just the HDMI cable to the TV, I change the sound setting on the PS3 to HDMI. I confirm that the TV is passing through the sound from the PS3 to the receiver. I try to play a bluray movie and a game, but the audio does not seem to switch to DD/DTS, it stays in its 2 channel matrix/dsp setting which usually means a digital signal is not being seen. It's like the PS3 is only sending 2 channel through the HDMI cable. I did select DD/DTS as supported. I tried changing to PCM which obviously didn't work in my case. Tried different cables. I know the wiring is correct, and the TV is passing through the sound from the ps3 to the receiver but just seems to be in 2ch only. I connected the optical cable, and switched it, and everything is fine, but just lost a little convenience of just having to switch the TV source and keeping the receiver on one source.

That's unusual, but some sets do pass through encoded multichannel sound.
This is likely an HDMI handshake issue. When the TV identifies itself as a two channel device, that's what the PS3 sends, a two channel downmix. It's still digital, but not the encoded DD 5.1 or DTS track, just a PCM stereo downmix.

BIslander, thanks for the quick reply, yea I heard it to be very unusual for the TV to pass the sound from the hdmi source through its coax/optical output, so it was quite surprising for my $750 philips to do it heh.
Your explanation about why it is only passing 2channel makes sense, probably right on the money too. So there is no way around this unless Sony makes an update? Perhaps I will email them.

Actually, negotiating the audio match between the two devices is the preferred performance, so I doubt Sony will be doing an update to remove it.
Is there any reason you don't simply run your audio directly to the AVR? Any switching complexities can be fixed with a good universal remote such as a Harmony. It's generally better to use separate inputs on your AVR for each device, which allows you to fine tune the set up for each one without affecting the others.

here's a question. I just connected the PlayStation 3 to a Denon 4308 C. I. receiver with my HDMI cable. I'm also only getting two channel output. Do I have to switch back and forth between Bitstream and PCM if I want to play games versus listen to DTS master Or other high definition lossless audio on blueray?
Thank you very much for any answer in advance.

wrong thread, head over to the PS3 forums, you just have your settings wrong. good luck!
