PS3 looses voice (retains music) on uncompressed

1411 Views 15 Replies 10 Participants Last post by  jlr29
Hello,


Last night, I had the second occurance of this. Thought the first was a fluke about two months ago, but there does seem to be a problem.


I have a PS3 and twice now when I start watching a movie and switch to uncompressed PCM, I can head only the soundtrack music and not the voices. I have HDMI into Denon 3806.


This movie was Pirates of Carribean #1 (POTC #1 and #2 arrived from Netflix yesteday). The other was Eight Below.


The solution is just to stop the movie and restart it, or cycle through the audio tracks.


I'm unsure it it was dropping the center channel entirely, but it is odd to hear the soundtrack and not the voices. I'm pretty sure it is the PS3 (latest 1.70 firmware).


Anybody else have this?

I haven't noticed this problem in my setup. I also have a 3806. But I run my 1080P output from my PS3 to a Connectgear HDMI splitter and send one output to my 3806 for audio and one to my VP 50 for video.
I don't have that problem with my PS3, I am using the Sony DG810, no splitters or anything else in the path.
Music soundtrack and voice are all encoded on the same track. Tha fact that you heard music means that the player was sending out the audio all the time. Your problem might be with the central channel. Check your speaker cable first, make sure it has a good contact to the post. Then re-check your receiver.

Also you might try changing audio to STEREO mode. This will re-direct the dialog to FL and FR speakers. See if this changes the story for you.
Don't know if it is related, but once I was watching the beginning of 'Blazing Saddles' and noticed I was only hearing the music - no singing. I then realized my center channel had cut out and I had to adjust the wiring on it. So there are some parts of some discs where voices are only encoded on the center channel.

I was under the impression that the majority of dialog came out of center only when working with 5.1 sources.
If you are playing the PCM track, and you don't have HDMI into on your receiver, you only get the left and right channels. This is because the PS3 does not re-encode into DD or DTS for backwards compat.


e.g. Crank defaults to PCM. I have to manually select DD from the disc menu because my Meridian processor does not offer HDMI input, so I must use SPDIF.
Dirty Dancing defaults to PCM also. I was using my headphones last night so I didnt notice until the movie was almost over. My optical reciever was matrixing the 2 channel PCM to 6.2. The voices sounded fine though. Must be that the 7.1 or 6.1 PCM track on Dirty Dancing is all taken from a 2.0 track. The box says 6.1 but the PS3 said 7.1.... who knows ?
definately not a wiring issue. I've watched over 100 movies, both HD DVD and Blu-ray Disc, using PCM sound via HDMI, and only these two isolated incidents of this with the PS3. It could be something with my receiver & center channel possibly. If/when this happens again, I'll try fiddling with the receiver to see if I can get any voice out of the left/right speakers, but actually, I think it is more likely the processing of the PCM in the PS3 - namely it just isn't sending out the center channel to the receiver and only the left/right speakers. Just a guess and was wondering if anybody else had seen it. I guess I too quickly restarted the movie and then couldn't really investigate the problem since it was working OK then.


Thanks
I remember reading here awhile back that setting the HDMI audo output to Bitstream would also send the PCM track as well, the advantage being when your watching a disc that is only Dolby Digital or DTS you get the bitstream sent to your AVR. I set it at that and it did work, like the Toshiba HD DVD players that can be set to HDMI Auto. PCM tracks worked but for some reason, Disney/Buena Vista/Touchstone Blu-rays with PCM engaged only sent L&R audio, no center (dialog) or surrounds. I now have HDMI set to Linear PCM. Has anyone tested this? I believe Robert George posted this as well. Every other PCM title played in 5.1 except Disney.
Interesting. Just watched POTC2 tonight and had the problem again. This time I listened to the center channel and surrounds and there was no sound at all, just L+R. I looked at the Denon 3806 front panel and it said multi-channel direct and had the little lights for 5.1 channels, so I don't think it was the receiver doing it. The PS3 is outputing 5.1 channels, just null signal for center and surrounds.


I DO have the HDMI audio output set to Bitstream. If I change this to Linear PCM, will I still get the regular DTS-ES 6.1 Discrete from some of the Paramount Blu-ray Discs that are encoded in that? I should get linear 6.1 PCM from these and not drop to 5.1, right?
First thing, if your listening to PCM your gonna have to change your HDMI output to PCM. The one problem I don't like abot the PS3 is when you have HDMI set to PCM and watch a DD/DTS encoded DVD or BD the PS3 does the decoding and sends it to your receiver as PCM. I hope in a future firmware they add HDMI auto like the Toshiba HD DVD players, where it would know when to output PCM and bitstream according to disc.

That is how the PS3 actually works. If you set the output to bitstream right now it outputs the bitstream for DD and DTS, and PCM for PCM and Dolby TrueHD and DSD (for SACD). If you set the output to LPCM, it outputs PCM for everything.
Just watched another Buena Vista movie last night, but switched to LPCM ouput before I started and the sound was fine.


I don't know if we can blame the PS3's setting (which does seem to work as an "auto" feature for most Blu-ray Discs), when the culprit seems to be some of these Buena Vista discs, which might be encoded a bit weird.

You might be in denial mode but this will not resolve your issue. I also have a PS3 connected to Denon 3803, and am watching the same movies. The audio is awesome and the center channel is very articulate. No problem with it in my setup. From what you are saying it looks like a problem with the receiver.
I had this problem and it was my receiver. I have a Panny XR57 and I had the PCMFIX on so I turned it off and the dialog came back.
