192K/96K Stereo and Pioneer Elite SC-27 - Help !

[Living Stereo]

I have not been able to get my Pioneer SC-27 to show that it is playing audio from any hi-rez source. I have an Oppo BDP-83 connected via HDMI and an HTPC connected via Digital Coax to my Pioneer. I have been trying to get it to display that it is playing from a 96k or 192k source. It should appear on the receiver “192k Stereo or 96k Stereo”, but no matter what source, either my Oppo or HTPC, I play the receiver will not recognize the high-rez signal, it just says “Stereo” I have tried the PCM tracks from both the Rush Moving Pictures Blu-Ray and the Yes- Fragile DVD Audio discs. If I switch the pioneer to say Coax-2 with nothing plugged in to that jack, the receiver says 192K Stereo, not sure why. What am I missing here, is there a setting in the Pioneer that I have missed. I have checked all settings on my HTPC Software (which works fine on an old Yamaha AV Receiver , the Oppo and the Pioneer Receiver. I could have sworn that I saw it display either Stereo 96K or 192K in the past. Anybody have any ideas?

Let' start by reducing the variables for error - either the HTPC or the Oppo. I would take the HTPC out of the chain.

Does your OPPO have any automatic HDMI setup routines you could run it through?

Welcome to the forum!

I've looked through the manual but haven't found anything, yet.

What sound mode are you using on the receiver, and have you tried different ones (e.g. "Stereo," "Direct")?

I have tried all the sound modes, nothing. I have a old Yamaha RX-V 520 AV Reciever and if I plug the HTPC in via digital coax and play a 96k file, it shows on the front display 96K Stereo, I am sure the HTPC is outputting properly, The same with the OPPO, If plugged into the Yamaha, it will Show 96K Stereo or if I use a 192K file it will show "Unknown" as it does not do 192K, but it still plays the file. I believe the issue is with the Pioneer, but I have checked every setting in it that I can find, no luck. It's odd that the Pioneer will display 192K Stereo when switched to an unused Digital Coax input.

Hi. Is this thread on AVS from you? If so, I read that differently than what you stated here. Namely, your post on AVS states that the Pioneer will display 192k from the Oppo but not the HTPC, but here you state that the Pioneer will not display 192k for either input.

Please clarify the situation, as it goes towards if it's something with the Pioneer or the HTPC.

Also, make sure that your optical output on the HTPC (a) is capable of outputting 192kHz and (b) is set up to do that.

Yes, that is my Post. I am sorry about the mix up, I just recently moved, when I was at my old location, I defiantly remember that the Pioneer would display 96K & 192K and assumed it still did. I went back yesterday and tried out everything with the Oppo and the HTPC and now it will not. The Oppo and HTPC does in fact work with an old Yamaha, So I believe that something is going in with the Pioneer and not the Oppo or the HTPC. I just can not figure out what. I have tried every setting I can find on the Pioneer, but just can't seem to get it to work. I have scoured the manual, but did not find anything on this.

As far as the HTPC, much of it was built with the suggestions from Computer Audiophile, I used the recommended Asus sound card that outputs up to 192K. All settings in the Asus drivers and windows are passing a 96K &192K signal, this was verified by connecting to my old Yamaha RX-V 520 AV Receiver, it shows up on the screen "96K Stereo" when a 96K signal is fed to it. I cant get the Pioneer to show anything other than "Stereo".

 

[Adam]

Thanks for that explanation - I understand now.

It could be a setting in the Pioneer for sure (and probably is, as you've said), but perhaps in the other equipment as well. With moving, it's possible that the Pioneer and/or Oppo had some settings return to default because the power was cut for an extended time.

I'm heading out for a bit, but if no one has gotten you squared away by later this afternoon, I'll look into this more. I have a Pioneer VSX-23 and an Oppo DV-980H connected via HDMI, so I could even play around and see if mine displays the rate.

 

[Adam]

Alright, no solution, yet. I played around with my Pioneer and Oppo and haven't been able to get it to display "xx kHz Stereo"...except when I switched the input on my receiver that I'm using for the Oppo to Analog (which wasn't connected), in which case it read "96 kHz Stereo." I think that I tried every possible output stream from the Oppo HDMI connection, as well as trying all of the Pioneer's input selection choices.

One note, though - make sure that the audio that you are playing is either 96 or 192 kHz. My SACD's were 88.2 kHz, and the first couple of DVD's that I tried were 48 kHz. I finally found one that's 96, but I haven't gotten that display message, yet. I'll try a bit more later.

If you select the "STATUS" button on your receiver's remote (after selecting the "RECEIVER" switch on it), it will cycle through some information. The sampling frequency of the audio currently playing will be the second thing it displays.

I don't understand how any receiver would ever show 96kHz or 192 kHz stereo if you are using a digital coax connection. The s/pdif protocol does not support sample rates of 96 kHz or 192 kHz - you need HDMI.

I suspect that the receiver is showing the sampling rate the DAC will use when you switch to an unused analog input. Clearly it wouldn't be showing the format of an incoming signal if no device is actually connected and transmitting data.

 

[Adam]

The s/pdif protocol does not support sample rates of 96 kHz or 192 kHz - you need HDMI.

I beg to differ, MDS (a rare instance). At least some S/PDIF hardware will output 96 kHz and 192 kHz signals. For example, my Oppo at least allows me to set the sampling rate for the digital output to 48, 96, or 192 (above 48 is only available if I turn the HDMI audio output off).

 

[Living Stereo]

Well my Oppo is connected via HDMI, but my HTPC is connected via Digital Coax and it shows up on my Yamaha Reciever as "96K Stereo". At The moment, I can not get my Pioneer Receiver to show it at all, no matter what source is playing.

 

[ichigo]

PCs are capable of resampling to several rates natively through SPDIF. Including 88.2/176.4/92/192

 

[Living Stereo]

Well, I spoke to Pioneer Technical Support today, and they seem to believe that something is wrong with the receiver. They state that it should display 96K or 192K on the display if fed that signal. Today I connected a Sony Walkman to one of the analog inputs and the receiver is showing that is playing 192K Stereo even though that is not possible from a Sony Walkman. So may be something wrong with the Receiver.

 

[Adam]

Have you used the STATUS button to check the sampling frequency?

 

[Living Stereo]

Yes, and it shows correctly for my digital inputs, but shows 192K Stereo at all times with analog inputs. I am going to Best Buy-Magnolias (only Pioneer Elite dealer near me with some files on a usb stick and a few Hi-Rez discs to try them on their equipment, near the same of my SC-27 and see how they operate.

 

[Living Stereo]

Well, I got to play with a new Pioneer Elite SC-57 and a VSX-53 today too see if they operated any differently. On the digital side they behaved just like mine showing only "Stereo" on the display and showing either 48K 96K or 192K only if you press the status button on the remote. Unfortunately they did not have anything hooked up with analog inputs, but when an analog input is selected it just says Stereo, unlike mine which is showing 192K Stereo at all times on the analog inputs. Best Buy Magnolia's is a bit behind the times at this particular store, all the sound rooms are set up with Coax Digital and Component Video, so they can't even demo Blu-Ray at 1080P. I was able to use the SC-58 with a Panasonic Blu-Ray player connected via HDMI though. Bottom line is I still am not sure that my SC-27 has a problem, but if this is the way it is supposed to work, I think Pioneer took a somewhat strange path as far as the design in this area.
