Quick Question about reciever and blu ray

[HDFan101]

Well lately i have been noticing that my denon 3808ci reciver front panel led displays DOLBY DIGITAL or DTS SURROUND, when watching a blu-ray. I have a DMP-BD30 PANASONIC blu ray player and i have it hooked via hdmi to reciever and then hdmi from reciever to tv. I have the settings for DOLBY DIGITAL, DOLBY TRUE HD, DTS, DTS HD MASTER AUDIO set to BITSTREAM on the blu ray player. It always showed on my recievers front panel either Dolby TRUHD or DTS HD MSTR. Now it shows if it is dolby true hd, it shows DOLBY DIGITAL and for DTS HD MSTR it shows now DTS SURROUND. How do i make it go back to showing Dolby TruHd and DTS HD MSTR?? i think what caused this was the latest firmware update 2.9 i don't know though.

Thanks Guys!

First thing to check is the movie that you are playing. Have you verified that you have selected TrueHD or DTS-HD MA in the disc's menu? Remember that a lot of movies startup with the lossy tracks by default.

yea i do that all the time i put on avatar today and i went to setup boom it was there i hit enter play and DTS SURROUND. I always change the setting matter of fact im going to do it again with another blu ray one with Dolby True HD.

Also just to add...make sure "secondary audio "is set to off on the player menu..

Secondary audio needs to be Off. Otherwise the player will decode the lossy track, mix in secondary audio, and re-encode a lossy track for output.

It sounds like you've got everything hooked up properly. Have you looked in the receiver's settings to see if something got changed accidentally? Also, you don't also have an optical cable run from the player to the receiver do you?

I tried 2 movies 300 with a dolby true HD and inglorious basterds with a dts hd ma and i selected both from the menu and then played and went to pop up menu and picked it but it displays DOLBY DIGITAL and DTS SURROUND. I have secondary audio set off and the only things i have plugged in the back of the blu ray player is the power cord, hdmi av out, and monster coaxial cable for digital audio out pcm/bitstream.

I have dynamic range compression set to off and PCM down conversion set to off, is that okay?

Yes. Did you check the receiver's settings? If I'm not mistaken, some receivers can't apply some sound fields or matrix the surrounds with the lossless tracks. I may be off base, but I'm just trying to throw suggestions out there. You might have to call the manufacturer. It's got to be something simple like a setting, since you were getting the lossless audio previously. If you change to PCM over HDMI, does your player have a display to tell you which codec is playing?

what do u mean by change to pcm over hdmi? I went on the blu ray player setup and changed the bitstream to pcm and it played DOLBY PL II cinema. What should i look for on the reciever? Do you think the blu ray firmware update caused this 2.9? Thats the last thing i could think of.

Ok, PCM causes the player to decode the audio (bitstream causes the receiver to decode it). Can you select something on the receiver like AFD (auto format decode)? Turn off Pro Logic II and try to make the receiver decode the audio exactly as is. This means, for CDs it will play in 2.0, movies will play in 5.1 (and hopefully as TrueHD and DTS-HD MA). You will need to make sure your player is set to bitstream the audio over HDMI, and turn off all processing on the receiver (most receivers have a button on the remote that is labeled AFD).

I fixed it i don't know how this got changed but i went to Source Select > Blu-Ray>Input Mode>Decode Mode. The options were as followed Auto, PCM, DTS. PCM was selected so i was like wtf? I put it on auto i figured that would do it and it did. I don't know who keeps changing it, im going to try a dolby true hd now. Can i put a password on my reciever? denon 3803 ci

That's it! Glad you got it fixed. I can only about the vanity light on the front of my receiver. I've never seen it because my fatboy PS3 can't bitstream it over HDMI (hence, I have to use PCM).

Oh that sucks ps3 lmfao wheres your 360 at. Anyways thanks again everyone for all the help!

360 can't even play blu-ray and hasn't even been turned on in the last year.

Glad you found a solution, although I don't quite understand what you did.

For future reference, those settings have no effect on bitstream. They only affect the player's PCM output.

The receiver was trying to receive the signal as PCM, but the player was bitstreaming it. He changed it back to auto format decode, which will take whatever signal the player is sending (in this case, TrueHD).

That's what makes no sense. If the player is bitstreaming a lossless codec and the receiver is set to only process PCM, the result will be silence. The receiver will not do lossy decoding. With TrueHD, the lossy track isn't even being sent to the AVR. So, how would the receiver report DD 5.1?

I think it was taking the lossy core track. Some receivers can't apply sound fields to the lossless codecs, so it takes the lossy to do it. By taking AFD, it's receiving it exactly as the player is sending it.

There is no lossy core track with TrueHD. The TrueHD package on the disk includes a separate, lossy DD 5.1 track for backwards comaptibility. Only one - TrueHD or DD 5.1 - gets sent to the processor. The AVR cannot extract a track that isn't even there. Besides, receivers that can't post process while doing lossless decoding simply do the decoding. I've never heard of an AVR that does what you describe.

The AVR only reports DD 5.1 and DTS on its display when the player sends DD 5.1 and DTS. When set to bitstream, the player uses the HDMI handshake to determine which track to send. If the AVR has lossless decoders, the player sends lossless. If it doesn't, the player sends lossy. Receivers do no substitute one for the other on their own.

I don't claim to be an expert. There are some discs that only have the TrueHD track (Star Trek 2009, for one). What does the receiver do with those if it can't decode the lossless? Doesn't it play in DD? Plus he was having the same problem with DTS-HD MA, which I know for sure has the lossy core track.

In any event, when I saw that it applied PL II when he changed the player to PCM, that told me that something was happening on the receiver's end. The only time PL II kicks on in my setup is when a signal lower than 5.1 is received. I suggested he verify that AFD is selected. He checked it, it wasn't, and that solved his problem.
