The real issue may be HDCP 2.2...Which only the Nvidia gtx 960 and 950 possess.

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.

And both are only HDMI 1.3 compatible. Bye bye 3D and 4K. And it only corroborates what I was saying too. For PDVD to output Full HD 24bit audio, you need a secure audio path, either via HDMI or via the very few certified audio cards.

You guy's gear doesn't have anything to do with that anyway, as I understood you're using USB... which is not secure. So you have all that fancy musician stuff and can't enjoy Full HD 24 bit Audio, which was my point.

I'm not denying you guys know about stuff, but beside my basic HTPC installation which I enjoy in my small office at home, I also work daily since 20+ years in the video industry (software engineer) and I happen to know a bit about those secure path "problems".

Now if you want to output Full HD 24 bit via non-secure audio devices, there are tricks I can give you if you send me a private message, notably a well known and quite cheap little piece of software which is also very well supported by its developers, and which doesn't have a problem with HDMI 1.4 or even 2.0.

Well, yes they are both only 1.3....but most of us audio geeks will run a second cable directly to the display for video only (just like the Oppo has 2 hdmi outs). I hate 3D, and 4k...I can run that directly from my video card to my TV and use a different HDMI in my PC as the default sound to the Evolve...problem solved. The Evolve is one of only a few HDMI DAC's - Motu has one also. with these you can enjoy full 24 bit audio. Most people that are using audio interfaces are doing other things (as you mention) to get around HDCP. I'm just showing you that you can keep the protected audio path all the way to a few specific DACs without using software that defeats HDCP... or using a receiver. I happen to own an Evolve myself - I actually have several different soundcards, interfaces, and DACs to be honest.

The issue of 3D once again ....it's a dying fad. Now 4K...That will be a different issue for us that have screens larger than 100 inches - looking forward to that....like I said, I'm prepared, multiple HDMI out....with protected video path for video and the other, protected audio path to the DAC - and still, no receiver involved.

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.

Quote: ASIO vs bitstreaming... you really can read all kind of funny crap on these forums.
ASIO does NOTHING for a fully digital bitstreamed audio track, be it mono, 2.0, 5.1, 7.1 or atmos.
ASIO is for musicians.

Excuse me...I wasn't talking about bitstreaming. Those of us that use softdecoders do not bitstream our content to a receiver or prepro. ASIO is being used by many of us that have transformed our PC's into high-end prepros, ASIO is a great way to set up an active digital crossover (using an amp on each driver - such as the woofer, mid, and tweeter - each having its own amp). And yes I'm also a musician - and the RME...it's a musicians sound card, and a DAW is a digital audio workstation. You can do this http://www.acousticfrontiers.com/201366how-to-replace-your-home-theater-pre-pro-with-a-htpc/. Although he uses a competitors product - there are plenty of programs that we use to process our audio, such as Audiolense XO, Dirac Live, the Ultimate EQ etc. You may be in IT, but you are showing that you lacking in computer audio knowledge. Go over to the computeraudiophile.com or to thewelltemperedcomputer.com to get a gander of what's being done.

Quote: I don't agree with your last statement.
Many av receivers have added support with a firmare update so it can't be that hard to implement. Bluray players support it too.
Also my soundcard drivers allow me to route my inputs and outputs anywhere (including adat out) for 100's of tracks for use in a daw.
It's just essentially panning info and as cyberlink pay for dolby licensing anyway (I assume) they should already have the license to do it.
I would have thought it would have been on pc way before being supported in firmare updates for AV receivers.
Don't cyberlink read their own forums, a estimated release date would be nice to know.
Thanks for the link!

You're using ASIO for your RME right? Your tracks are not limited by your OS at all, only by the number of physical connections available on your RME sound card. Off topic, are you using the Hammerfall?

This elitist attitude and misinformation is not helping anyone!
Atmos uses audio objects and spatial coding.
Read it on their site.
http://blog.dolby.com/2014/09/dolby-atmos-goes-cinemas-living-rooms/
the first software player to support this new format will be getting my money.
I use an RME sound card which is better quality than most amps, through balanced outputs going to active studio monitor speakers.
I'm going to add extra outputs to my RME fireface via ADAT to get as many speakers in my room as possible.
To the people who can't get their heads around people not using receivers/decoders; if you go the audio interface route you are not forced to upgrade receivers/decoders/amps every time a new format (like atmos) comes out or a new HDMI spec comes out (like HDMI 2) etc.
An update from a cyberlink employee to give a time scale on when we should expect atmos support would be appreciated.
I'll be posting something similar on other home theatre application forums.
Thanks!

Excellent Post!!!!! I have a spare interface myself (but I'm looking at getting one of the new Motu interfaces)! You are correct! First software player that has Atmos - has my money, even if I don't convert immediately - its nice to know that I can (I'm capable of supplying 8 more channels of amplification to my system as it stands aready)!

Well - there happens to be a slew of people that currently use their HTPC's as preamp/prepros as well - eliminating the need for a receiver. All they do is add power amps and have a high-end multi channel sound card (they let the PC do all of the processing). These are the people that are waiting for Atmos in players such as Cyberlink PowerDVD. The first one that offers it - I'm buying it in a heartbeat! I don't need new receivers that become antiquated or bricks before the next format! I love having a PC I can fix and or trouble shoot...all I have to worry about is software!
