I have A Panasonic DMP-BD65 blu ray player, which is connected to my Panasonic TC-L32U22 TV, which is connected via digital optical audio cable to my Xantech optical to coaxial converter, which is connected to my Philips HTS3566D/37B 5.1 sound system via digital coaxial cable. But I have a question. My blu ray player can decode dts hd master audio, dolby true hd, dolby digital, etc., but my receiver comes built in with only a dolby digital and dolby pro logic II decoder, because it's pretty old. I don't intend to watch movies with it though, that's what I use my blu ray player for. So since the blu ray player already does all the decoding, can my receiver play the audio via digital coaxial audio cable? Or does it need an external decoder to play those formats? I figured only discs I viewed on the receiver would require that.

Lossless audio requires HDMI, so you are out of luck on DTS HD-MA/Dolby True HD.


Also, most HTiB such as yours are only equipped to decode DD(not DTS or anything else) via the tos-link input.


So read your manual and it will tell you what it can decode via its tos-link.


Also, the way you are doing it, all you are getting is 2.0 PCM, so there is no point in using anything other than DPL II.

Optical and digital coax are limited to the older lossy codecs (DD 5.1 and DTS) and to stereo PCM. So, there is no way to get multichannel lossless audio with your current equipment. Also, most TVs only output stereo from equipment attached via HDMI.


So, you should attach your BD player directly to the sound system rather than running it through the TV. Set the player's Dolby Digital output to bitstream. Then, when you play a TrueHD track, the player will output DD 5.1, which your system can decode for high quality 5.1. If your receiver cannot decode DTS, set the DTS output to PCM and set the downmix to surround encoding. The player will fold the center channel and a mono surround channel into the stereo output. The PLII mode on your sound system will extract those channels back out for pretty decent surround.

OK thanx for sorting that out for me. The thing is, I know my tv can do uncompressed audio through HDMI, but I don't particular enjoy the sound my tv produces. Even though it's at a higher bit rate than my receiver, the bass makes a horrible "buzzing" noise when turned too high, forcing me to turn down the volume. It just isn't as rich as home theater speakers, which use a subwoofer. So I'll go with the dolby digital/dts through coax. Mainly because I just want everything connected to my tv to be connected to the receiver.

And one more small question...

If my Wii is hooked up to my tv by component, will the audio still be able to pass through the digital coax to my receiver?

Yes, the TV can do uncompressed audio over HDMI. But, it's only stereo and uses lousy TV speakers. The TV will not pass multichannel audio out to your sound system, which is why you should attach the player audio output directly to the sound system.


Yes, your TV will likely pass the analog stereo audio from the Wii to the receiver.

You answered my Wii question, but what do you mean my tv won't output multi -channel audio? If you check on the website, it says that the digital optical audio output outputs 5.1 ch audio, which is exactly what i need for my 5.1 receiver.

Most TVs only output DD 5.1 from their own internal tuners. Audio from devices attached using HDMI is usually limited to stereo. Perhaps you have one of the sets that will pass DD 5.1 from other sources, although I've never seen that feature on a Panasonic.

Read the manual on the page where it shows you how to connect a tos-link to an outside audio source. (most owners manuals contain the pertinent info on what exits the Tos-link in the "notes". More often than not, the "notes" are more important than the rest of the manual)


98%(if that low) of TV's only send 2.0 PCM out the Tos-link. The ONLY THING that goes out 5.1(again on AT LEAST 98% of the TV's made with a Tos-link) is the tuner...not even the apps(Netflix).


Read your manual(s), the answer to your question(s) lies there.

Hi Ninjadude973, see notes at bottom of page 27 (downmix HDMI input audio to 2Ch) and page 43 on "Digital Audio Out" section for 5.1 (from tv tuner).

Yep you can get a real receiver that can handle lossless blu ray formats for $200, end your headache and do yourself a favor and pick one up.


Although I didn't look at your gear listed. There is another way to get lossless audio to a receiver. Like he mentions let the blu ray player decode it and send it to receiver through the rca jacks into the reciever. But I agree you're just much better off buying a real receiver and solving all your problems.

Since blu ray soundtracks employ a higher quality version of DTS and DD, and considering the speaker/receiver you have, getting the HD version of the audio will not make any appreciable difference.


Hook the blu ray player directly to the receiver (optical or digital coax) and that is all you need to do to ensure you can get the DTS or DD. Don't worry about the HD codecs until you are ready to upgrade to a receiver and speakers that will do them justice.

Not in any way.


If you have a player that decodes HD formats and has 8 channel analogue outputs, and if you have a receiver that has a 6/8 channel inputs (they are RCA style inputs) then you let the player do the decoding, and that decoded signal is sent to the receiver. That will allow for HD sound through a receiver that does not decode HD formats itself.


If you connect the red and white RCA cables directly, you will get stereo only.


If you connect optical or digital coax directly, you will get 5.1 via high-bitrate DD or DTS.

Except his Phillips HTIB does not decode DTS.


That's why I suggested he replace the receiver.


He could get this receiver by joining Club Onkyo (free sign up) for $129 shipped.

It appears 5seconds just confussed you even more. You cannot get lossless audio via optical or coaxial or red/white cables.

Basic wiring 101. Modern preferred wiring scheme. Connect all input devices to audio receiver with a single hdmi cable. Then connect receiver to tv with hdmi. Done.


Second best option. Connect the video inputs to tv and audio to receiver with a single digital cable. This can be toslink or yellow rca. The red white cables only carry analog. Avoid these cables and connections whenever possible.


Third best option. Connect everything to tv and then send audio to receiver. This is what you have been doing. It works but not very good. Try to avoid this wiring scheme. A single digital cable will carry a 5.1 audio signal but a red/white cable is only 2 channel analog stereo. Forget lossless you aren't even getting digital surround sound.

So should I set the blu ray audio settings back to bitstream since the cables can't support lossless anyway, or should I just leave it on pcm so that my player decodes it, then sends it to my receiver (but only in stereo)? Or is there still no lossless even in stereo?

If I abandon all this and just use my tv speakers which play the lossless audio from hdmi, I'll get the "best" sound, but the thing is, it isn't the best sound in my opinion, because I don't enjoy my tv's horrible bass. I'm beginning to think lossless isn't worth it.

"I'm beginning to think lossless isn't "


No your worthless HTIB wasn't worth it. Buy a new receiver as they point out they are extremely cheap at this point. And from what I can tell , you'll NEVER be getting lossless anything via the tv, period. You're wrong in that it does Lossless audio.
