My z1000 pro wil not output pcm bitstream wen I play the movie red tails its auro 3d pcm it wil not play it in bitstream only lpcm so no auro to the receiver What can I do about it
With regard to multi-channel PCM soundtracks... IIRC, my older X9s was not able to play these? And some of my older Bluray discs had lossless 5.1 PCM soundtracks and there would not be any audio output.. I would then always use the multichannel FLAC option in MakeMKV when I would rip any titles like this in order to still have a lossless soundtrack option.. I haven't had the opportunity to try my Z9x with PCM files like this, but I wonder if it still is the case?
I use the denon x8500ha as a processor end 3 parasound 51a for amplifiers. In the bedroom I have a denon x6300h end a zidoo z9x it has the same problem no auro over pcm whit red tails
If the track is encoded in PCM there is no bitstream. Auro can be carried either in a DTS-HD bitstream or a PCM track so unless you have a DTS-HD track as well you won't get a bitstream.
It's a pcm track my pioneer bdp lx71 plays the disc whit auro my panasonic ub9000 can't play the pcm track in auro zidoo can't play it
The Auro layer is encoded in the PCM track and if the PCM track is not played back absolutely bit for bit as laid down on the track then it won't be decoded - the PCM data may be intact, but the Auro data is modified too and therefore useless. Because of the nature of PCM tracks, they are usually not bit perfect to the source when they come out of a player because, unlike encoded bitstreams like DTS and Dolby, PCM can have volume changed, emphasis changed etc etc - and that entails modification of the digital stream and there's usually some of that going on internally too. One thing you could try, although I doubt it's going to work, is to disable volume control on the Zidoo (Settings/Audio/Volume Direct Mode).
It did not work I found on the zappiti form it works whit zappiti to play red tails in auro 3d Then it can be made to work on a zidoo
So, just to be clear... Is the Zidoo able to output multichannel PCM movie soundtracks? With my older Zidoos, I recall not getting sound when picking these soundtracks on early blurays that used this "lossless" audio format. Thus I would rip in the FLAC format instead for these relatively few titles. Or was it because I had my Audio preference set to RAW and possibly my volume output set low? Thanks...
It can output multichannel PCM just fine, so if you have a file with a PCM multichannel soundtrack, that works perfectly. In fact the the hardware is capable of decoding into PCM also, it's just not licensed to do that.
Weird, mine have never worked.. at least on my X9s and Z9s models... obviously not an issue now as there hasn't been a PCM soundtrack Bluray in years... and I haven't needed to play any on my Z9x.... this shouldn't have been an issue with earlier versions how MakeMKV ripped the file would it?
Yep - just tested a Z9S and that showed "None" as the audio track and no audio output - Didn't test, but I assume it's the same with an X9S too..
LPCM is a subset of PCM, I'm just using the term "PCM" to denote the mode of quantisation, ie Pulse Code Modulation. That response was not in regard to Auro-3D.
