Go to Player Settings > Video, Audio, Subtitles and then click the More Audio Settings button. Check if the "Exclusive audio output" option is selected. If it is, deselect it.

Already tried that. Sadly, that makes no difference.
To recap:
1) The same LPCM stream plays fine when muxed inside an m2ts container;
2) when played from an .mkv, however, PowerDVD reports 'unknown audio format' on the same LPCM stream, but ONLY when muxed together with a 4K video stream.

I get an 'Unsupported audio format' when playing HD Audio (LPCM) inside an .mkv file. Works fine with .mt2s files. What gives? Just bought PowerDVD 21 Ultra today.

Hi memeiriver,
Please see the attached picture.
Greetings
Hicham
I think you misunderstood me. I have PowerDVD configured to accept the Remote App, and it gives me a code, but it's the App that doesn't offer me a place to input the code.

I don't think my PowerDVD Remote Free App is working properly (PowerDVD 16). I followed these instructions:
Pair PowerDVD Remote with PowerDVDConnect your PowerDVD Remote device (your mobile phone) and PowerDVD device (your PC) to the same wireless access point.
Launch PowerDVD on your PC. You will find a 4-digit passcode under the Devices/PowerDVD Remote tab.
Launch PowerDVD Remote on your mobile device and click the name your your PC with PowerDVD on server list.
Except I don't get a chance to type in any code whatsoever. Or any server, for that matter. It just says 'Finding PowerDVD', and then times out, saying it couldn't find it. So, at what alleged location am I supposed to enter this code?!

Memeiriver, powerdvd is not the last amp but it is the last decoder. Everything after that is just a wav that is converted to analogue by the RME.
All I know is, that my main PC (not my media center) just uses DVI (on a 1920x1200) monitor. PowerDVD is still telling me it's outputting 24-bit audio, which I doubt, as my audio card is just a simple Audigy (with no HDMI).

Our Dutch cows are both: either black with white spots, or white with black spots. ![]()
Anyway, like I said. what PowerDVD is displaying means as good as nothing. I highly doubt PDVD waits for feedback from your soundcard, to see whether a safe path was established (such handshake will be made, if applicable, between your HDMI audio card and your amp). Tl;dr: PDVD is not the final amp, so take everything it says with a big grain of salt.

You're wrong again. I've tested it just now to make sure.
It's outputting 24bit 48khz 8 channel.
Just right click and show information.
I'll take a screen shot if you want!
Audio: DTS-HD Master Audio 7.1 6219Kbps
Output: LPCM 48KHZ/24bits 8 Channels
'Outputting' is a tricky term in the hands of PowerDVD. Only your audio card/amp is the final decider over what gets output. When PowerDVD says 'Output: LPCM 48KHZ/24bits 8 Channels', what they really mean is 'Offered as 24-bit to the upstream audio processor.' It may well get downgraded to 16-bit on an uncertified path.

That is not true. My setup plays DTS 7.1 master audio fine.
You do know dts MA is just a 24bit (if you're lucky) 48khz (usually unless it's a music blu Ray) wav in a wrapper?
Nothing special, you're full of misinformation aren't you! ![]()
My RME will do 32bit floating point 192khz.
Get your facts right!
If anyone is misinformed, it's you.
Unless you use some kind of hacking software removing protections, if you don't have a secure audio path, HD audio is downgraded by any legal player, which includes PowerDVD.
Your RME doing 32 bit 192khz doesn't mean that's what PowerDVD sends it.
I know about it: before I switched to full HDMI, I was using a multichannel USB audio card with analog output, and since it didn't have a secure audio path, DTS MA HD Audio and also Dolby TrueHD were both downgraded to LPCM 16 bit even if the original audio was 24 bit. Unless I "cheated" with a protection removal software, of course.
No...there is a way for this to - You can have a protected audio path by using a HDMI De-embedder (another professional product such as the Atlona HD570 or the Essence Evolve HDMI DAC. No hacking software involved. You can bitstream to de-embedder (which happens to be HDCP compliant) and it will output to your power amps or active speakers and you won't pay $1k for a processing unit (i.e. a Receiver) that you will just have to replace in 6 months (especially with the poor Q&C with some units - you wind up with a high dollar dud inside of a year).
The advantage of PowerDVD and other software players is that experienced audio and videophiles can get rid of gear! The options that companies pour into product seems useless at times to me. PowerDVD should go after Atmos, or even a real PEQ that you can load measurements from REW into.
Yes PowerDVD and other competitors will output TrueHD/DTS-HD MA as 8 channel LPCM, but it will downres to 16bits/48khz. However this is avoided if you do bitstream to a DAC and let it convert to analog for you (as you know the original fat PS3 couldn't bitstream - only output LPCM over HDMI). This is basically what most people do when they hook it to a receiver - they are just using their receiver (and all of the unneeded functions) as a giant DAC. Using a simple de-embedder takes all the receiver stuff out of the signal.
Oh, fyi....by using a de-embedder - you could actually get PowerDVD to not downres the material - Powerdvd can decode send it out full resolution LPCM via HDMI to the Evolve (set the Evolve to 7.1 instead of bitstream) and you can have your post processing intact such as Room Correction and PEQ using Equalizer APO. Korrigan - I just want you (and Cyberlink) to see the possiblities, not to argue with your or discredit you. Wouldn't you like not having to buy a new receiver every time a new feature comes out? Even if you use inexpensive receivers - the money adds up over time.
^^ Good stuff, here ![]()

Not sure what you mean by 'protection removal software' here, as the check would be done inside your amp; but I'm pretty sure you can only send LPCM 2.0 over anything non-HDMI (or downgraded-to-16-bit LPCM, like you said).
LPCM itself, of course, can and will be received at 24-bit by your amp, though (when the stream is the latter, of course); but yeah, only over HDMI.
As for software, not sure how I'd go about testing what the actual bit-depth is PowerDVD would be using.

The only reason they seem to be adding atmos into the 7.1 stream at the moment is in order to make it backwards compatable.
Yes. Amps are supposed to disregard the audio metadata; which is why this can work with current equipment. Basically, the 7.1 is just regular (static) channel info, and the 'pinpoint localization in the soundfield' is only done for the .4 Atmos remainder. I suspect we'll see true Atmos streams one day, with no discrete channel info at all (and only the spatial coordinates). Like I said, I think decoding, for your HTPC needs, may prove quite difficult (if you want the data translated to a discrete, fixed channel set-up).
If you wouldn't mind posting a link to that interview as it is some info I haven't come across before. Atmos takes up 20% more of what btw? The bluray? The 7.1 audio space on the disc?
Here it is: http://www.highdefdigest.com/blog/dolby-atmos-followup-answers/
He also said it wouldn't affect bitrate for the video.
He said they "don’t expect video bitrates to be compromised [due to] the addition of the Dolby Atmos soundtrack on a Blu-ray disc." 'Not compromised' is a bit vague, though. When do we call video bitrate not compromised? He probably just means they think the bitrate won't be materially impacted. And, indeed, adding a 3D version of the movie on the same disc will affect bitrate far worse.
In the future I imagine to render like a game. No individual channels just flags for every sound. It won't take much processing at all! I think you under estimate the power of a modern pc. If I can play a game in 7.1 being rendered in real time (gfx and sound) I'm sure a modern cpu can pan a few audio objects around while playing back a pre rendered video.
I do not underestimate the power of the modern PC. Rather, I think it will be quite an uphill struggle trying to write an Atmos emulator; for one, because I don't expect Dolby to release the specs to the general population. So, what I'm saying is, don't expect libav to encode/decode Atmos any time soon. ![]() So, ppl will either need an official Atmos Amp, or use something like PowerDVD (You are gonna support it, right, Cyberlink?!). But Atmos over, say, XBMC, decoded to a set of discrete channels will be far off, I fear. Since 7.1 is the max LPCM currently support anyway, for now just using the ffmpeg trick (just discarding the surplus Atmos data) will suffice.

I think depends what you mean by implement. Do you mean: pass an Atmos bitstream to a suitable receiver\processor or undertake the decoding to x channels of LPCM etc.
I wouldn't have though the former would present too much of a probem. As to the latter, I can't see it happening in the short\medium term. There would likely be expensive licences to pay, complex set-up and a lot of processing power involved
Instead of just parsing several static audio channels, Atmos uses what they call 'pinpoint localization in the soundfield.' The way I understand that to work, is that Atmos channel data is more like spacial coordinates: aka, the Atmost processor is being told at what 3D location the sound should be placed, and the Amp will calculate, on the fly, how to distribute this over the connected speakers (hence why Atmos can support up to 24.1.10 discrete speakers).
'Decoding' to a fixed LPCM channel setup may therefore be quite difficult (until someone maybe manages to emulate a perfect Atmos processor).

Atmos audio doesn't take up more disc space. I'd love to see where you got that info from. It uses the audio that's in the 7.1 stream and just sends it though a different speaker. It doesn't have 4 extra audio tracks for the height channels like you are implying.
Sorry, Billy7, but you are thoroughly confused, on several fronts. For starters, Atmos data is only 'in' the 7.1 stream insofar it's packed on top of it, as it were, as metadata. As such, the entire stream naturally uses more disc space. In a recent interview With Dolby, their spokesman said:
Q: How much extra disc space will an Atmos track take up on a Blu-ray? Are studios likely to have to choose between either Atmos or 3D in order to maintain a decent video bit-rate, or can a Blu-ray accommodate both Atmos and 3D on the same disc without too much compromise?
A: This depends on the complexity of the content itself. Our initial goals are to minimize overhead to 20% or less. We don’t expect video bitrates to be compromised [due to] the addition of the Dolby Atmos soundtrack on a Blu-ray disc.
So, about 20% it is (and no magical 0%, as you were suggesting). Reading your earlier statements, it's clear your 0% confusion stems from your (erroneous) thinking that Atmos is just some sort of clever upmix. It isn't. An Atmos processor *can* take a standard 5.1 or 7.1 soundtrack and upmix it to the additional speakers you have installed, btw, but that's just like upmixing stereo to 5.1 channels.
The recommended minimum layout is 7.1.4 (the .4 are your ceiling speakers), but Atmos is capable of scaling up to more speakers if you install them. The Blu-ray version of Atmos can even support up to 24.1.10 (!) discrete speakers.

Additional data doesn't take additional disk space?
Yeah sure. I've been working for 20+ years as software engineer, and I have yet to find a miracle technology that permits such magic.
The new ffmpeg binaries can strip the surplus Atmos data, to turn what you have into a regular TrueHD stream again (with the Atmos data lost for now).

I have a similar issue with both my music and my movie libraries - after loading part of my music library, it quit. And it only showed the "preparing the media library" screen message for most of an entire day. I gave up, uninstalled it and then reinstalled it and then only permitted it to search my movie library. This worked, although slowly, and after a whole day it only got up to maybe half my movies (2K - I know, a lot but I have a 24TB RAID 5 disc array). So I quit and shut down the computer, and the next day when I loaded up PDVD14 - no movies at all and back to the "preparing the media library" screen, for about 4 hours until I gave it up as a bad job.
Contacted Cyberlink tech support and sent them a bunch of screen shots after updating to the latest versions of PDVD14 and all drivers for my i7-3770K system with AMD 7970 graphics card - no resolution. The last message I got (over a week ago) was that they had to kick it up to the next level. In the meantime I uninstalled PDVD14 and went back to 13, which had no problems. Will give them another week or so before I ask for a refund of my purchase.. Have no idea what changes they made in 14 from 13, but it seems like compatibility with certain systems is an issue.
Thx for the reply. Yeah, they need to get on the ball with this one. If ppl can't create proper music libraries, PowerDVD will lose part of its charm, and there are many other companies eagerly waiting to fill the gap.

Hmm, 200 views, and no one having the same issue? Gotta say, support here is rather, erm, 'slow.' ![]() (And no, I can't ask official support yet, as I'm only using a trial right now; and I doubt my old PowerDVD 8 license will still be good, LOL).
Seriously, though, if I can't use m2ts comfortably, or import my music library (see my other thread), a trial is probably really all I'll be using; which is a shame, as it seems version 14 made a lot of improvements.
|
|
|

Yeah, so why are m2ts files taking like 30 secs to load? That's 30 secs of black before it will start the movie (after which it plays just fine). .mov files, for instance, play instantly.
|
|
|
No one?
Well, after several hours I just gave up on it. I'm not even sure PowerDVD was actually 'scraping' anything at all.

Korrigan is correct. From the article cited: Note the date of release:
On September 30, 2014, Paramount Pictures will release the first Blu-ray Disc to feature a Dolby Atmos soundtrack with the #1 movie of the year worldwide, Transformers: Age of Extinction. Both the Blu-ray Combo Pack and the Blu-ray 3D Combo Pack will offer a Dolby Atmos soundtrack encoded in Dolby TrueHD. Paramount Pictures will look to support additional Dolby Atmos home theater titles via online streaming and Blu-ray Disc later this year. Dolby Atmos soundtracks are fully backward compatible, meaning they'll play on traditional home entertainment playback systems.
Thing is, even if they call it "Atmos" for maketing, a 7.1 TrueHD track remains... a 7.1 track. There's no support for the things that make Atmos so great, like more speakers and ceiling mounted speakers.
It's just like the supposed actual "4K" blu-rays... which are just 4K mastered, but are still 1920x1080 aka 1080p. It's marketing bullshit.
That's a bit of a bummer then. More like a fraud, really. Good to know, though. Thx.
Not sure. They can encode the additional Atmos data as "metadata" which the actual receivers are supposed to ignore (don't tell me about compatibility issues... this could be fun...). Thing is, Atmos for the very few who will have ceiling mounted speakers (do you have them? Most home theaters are still... yeah, guess what? 5.1!) will lessen the quality for the majority who are using 5.1, 6.1 or 7.1 systems. Because more (useless for the majority) sound data means more disc space used.
And that is why I don't buy Blu-Ray disks with both 2D/3D version on them, cuz it's just half of the usual space for each of them. ![]()
So it's not exactly a fraud.
Well, I was just going by your earlier statement, that:
"Thing is, even if they call it "Atmos" for maketing, a 7.1 TrueHD track remains... a 7.1 track."
I guess the meta-data really does contain the ceiling speaker info, but I have no way of testing that (I only have a 7.1 set, and no Atmos receiver yet).
As for quality loss, guess I'll have to mix the ceiling channels into the side-channels then, or something, and convert the lot to LPCM (resampling itself, of course, also means quality loss).

Guess you never heard of 'Transformers -- Age of Extinction" then? It has a 7.1 TrueHD, Atmos-laden HD audio track, to name one current Blu-Ray.
You seem to confuse 7.1 TrueHD and Atmos. That's definitely not the same thing.
There is NO actual blu-ray disc with a full Atmos soundtrack. For instance, TrueHD does NOT support ceil mounted speakers.
It's not because a movie in the theater was using Dolby Atmos that it's the same on the BluRay version... simply because the actual BluRay format doesn't support Atmos at all.
I'm not confusing anything. ![]() See:
http://www.blu-ray.com/news/?id=14840
The Atmos is woven into the TrueHD stream somehow (don't ask me how, but it is). As a result, you can't decode the TrueHD stream (wth libav, for instance); and eac3to can't recognize it either. It *does* play in PowerDVD and XBMC and such, though (no doubt sans the Atmos component).
