Title: Q5/Q10 pro and the 24bit/192khz passthrough for music?
Post by: kambei on May 31, 2016, 03:12:03 PM
Hi,

I rode that the Q5/Q10 pro are able to read flac music in 24bit 192khz using kodi interface without downgrade the signal, is thay true? Because I rode that the limitation was coming from Kodi and Android witch can't play more than 16bit 44khz.

I would to be sure because I will use the Q5/Q10 pro principaly for music and I want the best music quality. I didn't took the Shield TV because of the fact it doesn't do passthrough 24bit.

Second question, are they compatible with audio-gd amanero interface?
Thank you.

PS: Sorry for my poor English.

Thank you. I read this thread.

But I'm not sure to understand, le Q10 decode DSD,  but I would like to know if it passthrough  the signal.
I mean, if I you sens this signal to a DAC witch can't decode DSD, will it read this signal?  If yes, it's means that the Q10 downgrade the original signal.
I don't know if I understandable. 

Thank you for tour answers.

For FLAC file, it plays like charm, passthrough to my receiver which shown 92kHz and upper, I can not manipulate volume by the Q10 pro remote, which means it passthrough untouch signal to Receiver.

PS: Sorry for my poor English.

I can confirm the Q10 Pro will bitstream 192Khz 5.1 FLAC to a capable AVR. 
The built-in Media Center is the main video/audio player and there is a "wrapper" for Kodi to be used to by-pass Kodi's file limitations.

It plays PureAudio Blu-ray .iso files (e.g. Beck's Sea Change). 
I have also tested 24bit 88.2Khz FLAC (from SACD's) and 96Khz FLAC (from SACD's) and they all pass-through using RAW output on the Q10 Pro.
This means there is no processing at all from the Q10 Pro.

You will find in another thread here that an Android app HibyMusic will also enable playback of SACD .iso files (but this app does process the audio and output to PCM when I tested it).

I have the following issue.
I have downloaded several FLAC file to test my Q10Pro and my YAMAHA RX573 that is 24bit/192khz capable.
Set my Q10pro HDMI OUT to AUTO
using himedia media center, the test files were play at best of 96Khz, even multichannel, If I try to play 24bit/192 khz, no signal is shown on the YAMAHA display.
All test files were downloaded from here: http://www.2l.no/hires/index.html

So i try kodi 16.1 and wrapper too.
Select music and then browse my usb drive to play music. all files, even the ones tha were played well with himedia media center, have been played @48 Khz and only stereo.
So, what is happening;
Why I can't hear 24bit/192 Khz;
and Why all files are not played correctly on my Yamaha RX573?

Try setting all audio to RAW, RAW and RAW 7.1 (and not Auto)?  I use these settings to play 192Khz  FLAC on my Yamaha.

Q10 Pro has also SPDIF/Toslink you can try that route.

Tried it on my DAC/Amp it works.

This may be a silly question but I assume you have updated your firmware to the latest version? 
Have you checked the audio file you are playing with MediaInfo to confirm it is above 48Khz?

First, THANK YOU for your reply.
I am running the latest original 1.0.3 firmware (downloaded from here) and even my YAMAHA RX 573 has the latest (1.16)
The test file I have played is downloaded from http://www.2l.no/hires/
Here the pic





Another strange thing: if I put the USB pen drive with 192Khz 24bit file into directly to my AVR, it can not be played (unable to play) But I know that the AVR is 192Khz/24bit capable :(

Not sure what is wrong here but it is not the Q10Pro. 
I was able to download the 192Khz sample file  2L38_01_192Khz.flac from the same website and it plays fine through to my Yamaha, straight from the NAS.  Tested with Media Centre and also Kodi (which picks up and shows the metadata from the track).
Maybe check your AVR input settings?

What kind of setting I have to check?
Could you help me? In the link I posted above, there is also the manual. Please, could you be son kindly to help me.

I'm from http://www.futeko.com/newforum/index.php?topic=947.0 with possibly the same problem.
Let's help each other.

Firstly, some explanations about sound settings. There is no manual from vendor so it's my assumption. If I'm wrong somewhere just correct me.

All settings are there (except Volume): Settings -> PlayBack:

1. HDMI Output : what device send to AVR through HDMI. Possible values are: LPCM - player reads source file, makes some convertations and sends result to AVR. RAW - player reads file and sends to AVR without any convertations. Auto - player somehow desides what to do and choises LPCM or RAW mode. Close - does not send anything to HDMI.
2. SPDIF Output: the same as previous but SPDIF related.
3. HBR Output  : what to do with High BitRate(?) sources. Possible values are: RAW 5.1 - send 7.1 and higher sources to AVR only 5.1ch without any conversation or downmix it to 5.1ch (don't know what player really does). RAW 7.1 - the same as previous but 7.1ch related. Auto - player chooses something between described values and possible another ones that are not in menu (downmix to 2ch, resampling and so on).

I want the internal player to send music files directly to AVR. How to check it: I hear music, AVR shows the same samplerate as source has, optionaly volume can be changed only with AVR (it means player passtrough source streem to AVR).

I've tested with that source (2ch, 24bit/192kHz) - http://www.lindberg.no/hires/test/2L38_01_192kHz.flac
I've tested each test case below with all SPDIF Output values (LPCM, RAW and Close) just ommited it here to reduce post. It does not impact to result.

1-st test case (TS1):
1. RAW
3. RAW 7.1

2-nd test case (TS2):
1. RAW
3. RAW 5.1

3-rd test case (TS3):
1. RAW
3. Auto

4-th test case (TS4):
1. LPCM
3. Not allowed.

5-th test case (TS5):
1. Auto
3. RAW 7.1

6-th test case (TS6):
1. Auto
3. RAW 5.1

7-th test case (TS7):
1. Auto
3. Auto

The results are:

TS1: I don't hear music, AVR shows no signal.
TS2: I don't hear music, AVR shows no signal.
TS3: I don't hear music, AVR shows no signal.
TS4: I hear music, AVR shows 48kHz samplerate, volume can be changed with AVR and player.
TS5: I don't hear music, AVR shows no signal.
TS6: I don't hear music, AVR shows no signal.
TS7: I hear music, AVR shows 48kHz samplerate, volume can be changed with AVR and player.

To be sure that my AVR can play 192kHz source I've run the same file from another player attached to the same AVR. I hear music, AVR shows 192kHz samplerate, volume can be changed with AVR and player.

Could you please (or someone who read to the end) spend some time to run test cases and post results here?

Something is amiss here.  Using your TS1 settings (and Q10 Pro firmware 1.0.3) my Yamaha passes the 192Khz audio test file fine.
Your results (of no audio at all on RAW) are what was happening to me with the original (shipping) firmware.   
The difference for myself was the firmware.  I have always had the HDMI straight settings into my AVR. 
I use RAW, RAW and RAW 7.1 and now everything is working fine for my unit.  Unfortunately, I cannot suggest what settings on your AVR to change as there are too many variables.

Do 7.1 movie files and PureAudio Blu-rays pass HD audio to your AVR correctly?

I use the latests firmware 1.0.3 2016-05-23.124800 and it's happends only with 2-channel 24/192 sources.

Pure Audio BD 5.1ch 24/192 iso plays fine but when I switch to second track with 2ch 24/192 I hear silence. I've got both tracks to flac from this BD and 5.1ch flac plays fine too. 2channel does not plays. Hardware BD player plays both tracks without problem.

Anyway thanks for reply.

As I understand from video you runs following sequencies:

1. 2ch 96khz - plays
2. 2ch 192khz - does not play
3. multich 96kkhz - plays
4. 2ch 48 - plays

Is it right? If so and all your sound settings RAW then I'm not alone. ** demo is only stereo too for me.

Have you had a look in Kodi settings as there is a drop down box under Audio for limiting the output, by default this is not set at the 192Khz, I would check this out and apply setting and try again, you may have to change to Kodi Expert Settings to change this although I am not sure if this is the case.

I think only Himedia developers (or developer) can do it. And only when futeko will pay attention to the problem. Or hdmkv (with all my respect) will change that: "AQ = A+ (All formats bitstream great!)" at http://forum.kodi.tv/showthread.php?tid=265888. The only ones have direct conections with Himedia as far as I know.

Me, too. No problem with FLAC over 48kHz (show correct sampling rate on AVR, cannot adjust volume by Q10 pro). However, FLAC file with Sampling rate 44.1kHz show 48kHz on my AVR and Q10 pro still can manipulate volume for this FLAC file

Very very disappointed. Today i have recovered an 96 kHz 24 5.1 FLAC album that worked very well with my old  q10 4k3d and same avr . Show 5.1. now only stereo channel 48 kHz.
I have tryed HDMI auto but even raw and lpcm too, but no changes ... always  stereo
Support please

I presume you're playing using himedia player?

Can you post the mediainfo for the file? Or better still post a link to it for download.



I use himedia player.
I sent you a PM with a link
Thank you

Slow reply and testing, sorry. I have tested the file you sent by PM.

With Settings - Playback - HDMI Output set to LPCM I get 48Khz 2/0/0

With Settings - Playback - HDMI Output set to RAW I get 96Khz, 3/2/.1

So with RAW setting it passes as expected. That's with FW 1.0.5 and a Denon AVR1610.

I also tested a couple more multi-channel FLAC files and they play OK. And a couple 192Khz and they play as expected also.

I would suggest that those people not getting results like above look at firmware for the AVR, AVR settings, and cables. It is possible that there is an incompatibility with certain AVRs but the posts in this thread don't suggest a pattern so I think it unlikely. If a pattern could be established and a problem identified then HiMedia would be able to look at fixing it, but without a pattern there's not much they can do.

A potential related problem which is very easy to reproduce is the opposite being low-bitrate music files.
All MP3 files and (reported by others here)  FLAC at 48/44 KHz is output as 2 channels PCM passing re-encoding even when RAW is selected.
Easy to see as volume control of Q10 Pro now intervenes which obviously should not happen.

Greeting from Vietnam,
I am consulting to buy a Himedia Q10 pro to play lossless ( just CD quality) and send the signal PCM to my kenwood K531 (DAC built-in mini hifi system).
But I have heard somebody told that the sound via optical too small and need a power amp. I dont know with my kenwood RK531 ( 80W) can play with this optical output strength ?

Can anybody share the experience with your home system ?

Thanks so much

My Q10Pro is connected to a NAD D3020 with a fiber optical cable without any issues. The cable transmits data, nothing to do with power.

Still: any music files, like mp3 or FLAC are resampled from 24bit to 16bit and from 44.1kHz to 48kHz during playback.

I don't think that an audiophile or a sound engineer expert would agree.

Can Q10 pro passthrough the wav. (pcm) to the mini hifi system or DAC (NAD D3020) to avoid the re sampling  the bit rate 24 bit to 16 bit as most of the DAC process the PCM signal smoothly with higher bit rate (96khz/24 bit) ?

I accepted the storage for wav file will be larger than flac,ape, etc..

@stl : could you please help to do a test for me : play an wav file ( just stereo  audio) and choose raw output via spdif then confirm the sound is transmitted to your DAC correctly ?

Thank you very much.

As far as I can recall it, yes unfortunately the resampling occurs on the SPDIF outputs as well. This is some kind of Android limitation BTW, so most of the Android devices are affected. Only a few could have made this fixed (somehow).

Nothing in that Thread that confirms that it would support 24bit/96kHz on the SPDIF in the case of MUISC file playback. Rather than the opposite. See Reply #12 (http://www.futeko.com/newforum/index.php?topic=1172.msg9663#msg9663).

Using Himedia Music Player it played MP3, 24/96 Flac, 24/192 Flac. It can't play DXD (32/352.8 Flac) and DSD64 (.dsf).
->The playback of these files doesn't mean it actually did the output on these values and that no resampling did happen. I think that's what you may have confused.

However through UAPP (USB Audio Player Pro) it played everything the app could support. But it used the ASL (Android Sound Layer) to do this. Thus converted everything to 16/48 regardless of bit depth or rate.
->Which just confirms my previous presumptions.

16 bit 48 Khz is very good. There'e a reason why CD's are recorded with 16bit 44.1 Khz, it's because the large, large majority of people can't really tell the difference above it.

These complains mainly are regarding the fact of the resampling and beside the maximum limit of the sampling values. I'm not such a big expert on this, but any conversion/resampling (regardless if it UP or DOWN) ends up with some loss of the quality, that's a fact.  And most FLAC and mp3 files out there are 44.1kHz originally (and not 48), so those would be surely concerned. The decimation level of the actual SQ in practice is another story and -maybe- it's still bellow the average perception limit of most of the people. I just speak the theory.  But the optimal would be the perfectly untouched PCM bitstream on the original values of these music files, not matter what they are, which just won't happen 100%-ly in these cases.

Also note that lossless DTS-HD MA and TrueHD audio are passed through via HDMI.  The "Pure Audio" Blu-ray releases often contain these HD tracks in addition to PCM.
The "lossy" DTS 24/96 audio also is passed through without conversion to PCM and is clearly shown on an AVR.
