DTS DCH Driver for Realtek HDA [DTS:X APO4 + DTS Interactive]

[Ferather]

No there is no reason to install another Realtek, unless you normally have an additional APO system such as Dolby, DTS, Nahimic, then you might want the original driver.
All Realtek files are the same (given the same version), regardless of if the package comes with other APO's such as Dolby Digital Sound.

The legacy panel should work, although its based on the HDA driver, not the DCH driver (even my GPU driver is DCH), all features are considered legacy.
When Realtek went fully DCH, nearly all of the legacy APO's where immediately removed, not supported or built into new files.

Each Realtek device comes with a built-in policy, certain features will not be included with the devices policy, for example 24 bit recording.
My old 889 officially supported 24bit record, but I still needed to mod the policy to show it with Realtek drivers.

Other drivers such as Windows drivers, will ignore the device policy, its not programmed to read it, so Windows will show 24 bit record, without mods.

When OEM's finally catchup to 15 channel SPDIF, DTS can finally do more than 12 channels PCM, and we can actually use it.



12 channel analogue (6 cables), DOES NOT EXIST!

May they do it in Dolby first ?

 

[Ferather]

Dolby has multichannel [PCM] processing? And multichannel mode, with any number of channels support?

No. That's my question.

 

[Ferather]

Oh I see sorry, I read that differently, I guess probably not. DTS excel at multichannel over stereo, imo.

Thanks again mate! I'm in love with DTS and E-Apo

 

[Ferather]

Same here, I've tried a few different APO's. Some prefer Dolby with stereo or headphones in general, the app also looks nicer, more modern. DTS apps look a bit robotic, lol.

Before my 889 I had a Creative X-Fi fatality edition, nice hardware, terribad software and APO's, also don't like the speaker to spdif encoder.
The funny part is, the 889 (now on S1220-A, which is better still) ended up better than the Creative in sound output.

As a side note, SPDIF does not differ anywhere near as much as analogue per device (compared).

I have some spare money to spend on audio. Should I go for decent headphones ( using generic analog stereo ), a sound card, speakers, ears transplant ?

 

[Ferather]

I dont use headphones at all so I cannot suggest much, they physically hurt my ears after some time (not ear drum). I have had my Z906 for 10 years and still going.
Compared to some much more expensive AVR's they still have very high specs, Class-D, 4ohm satalites with > 110 SPL, not much to change.

I find it interesting how there is a few types of way to display THD specs, 10% would be 0.1% in some cases.

====

Edit: If I plug in headphones into My Z906 I get 5.1 to stereo, even with encoded audio. There is such thing as SPDIF headphones, but they are rare.

I'm always in untrust mode when readings specs of whatever electronic devices. Every vendor comes up with their own definition. Like what they do with "contrast ratio" or what happened in the day when audio in system speakers was advertised in Watts PMPO then, Watts RMS . So I guess that's what's happening with THD. They measure it in whatever circumstances they wake up with

 

[Ferather]

Some will show you the lowest possible number to represent the stat, giving you a false impression, 0.1% looks entirely different from 10%. It's BS x 100.
As a side note, you won't be able to compete with the full-dynamic range of a dedicated multichannel setup with proper LFE.

It's like trying to compare TV speakers with restricted space-size-width, to unrestricted dedicated speakers.
Headphones will ultimately save you on power though, little speakers cost little to run.

Also note, the high point of THD is usually the speaker its self, that's normal, a DAC should have a much, much, lower THD value.

you rolled that out of the sleeve.

Taking the chances to learn here. So ¿a PCM capable setup actually eliminates the distortion?
-----------------------

About headphones- I love them but anytime I can, I use speakers. it doesn't matter how good any headphone is. I'm also have some troubles with speakers in this matter of reliably represent sound in space. I just can't buy it. Well, literally but I mean , it doesn't convince me. To date, I have tried several devices and non feels natural. I guess PCM should be the better on this aspect . never paid much attention to what was playing the audio when I experienced it. Surely spatial speakers relies on the sound waves rebounding around but for my ears, it adds weird echo. And what can you do about it? Not much. if you use a foam ceiling on your bedroom you won't be able to listen the sounds from above. well, that's me diverging

 

[Ferather]

No PCM is what is sent into the sound device from an app, it then processes it in PCM, PCM is then sent to a DAC, which converts it into a power signal (analogue is power in a circuit).

If you are using analogue out (the pins), then PCM has already been converted to power, via internal DAC's (which is why the analogue portion of 2 devices varies).
If you are using SPDIF or HDMI, then PCM is sent out of the sound card, the DAC is inside the receiving device, which is static when comparing 2 devices.

"So a PCM capable setup actually eliminates the distortion?", yes, but it also depends on how good the DAC is in the receiver. Class D also makes a big difference.
Class D amps will keep the audio in the digital domain when amplifying it, reducing the noise floor to a minimum, compared to power amps.

I guess that's why they prefer to use fibre replacing copper in some audio devices. The D/A conversion process must add latency and chances of signal loss , right?

If you are using analogue out (the pins), then PCM has already been converted to power, via internal DAC's (which is why the analogue portion of 2 devices varies).

So how do they achieve pin re-tasking ? I mean you can use them as output or input points ( like blue line and pink line )

If you are using SPDIF or HDMI, then PCM is sent out of the sound card, the DAC is inside the receiving device, which is static when comparing 2 devices.

So if I understood it right, why does SPDIF even exist? Isn't it one extra step just because the end device treats the signal different?

That's clever approach. I love digital word but for sound I'm not sure if sticking on its side. For me it's like analog is the way to go just for the nature of how sound exists in the real world. I mean ,as vibrations

BTW sorry about all the inquiries . I feel like a kid learning

>> 100% correct, optical is immune to EMI and other type of conductive interference, and it does not use power, glass-plastic is an insulator.

Slightly off topic, but with optical internet, I can ping Google Australia from the UK and get 5ms response time.

>> Circuiting, here is a blueprint of my older 889, where you can see analogue with lots of parts, vs SPDIF.

>> Because working with power signals is never lossless, lossless only applies to digital audio, never analogue (lossy).

I updated my above post which should help you understand, PCM is digital audio, classed as lossless.

Thank you kind alien. I'll stop bothering you for today . Wish you the best

Fascinating but I'm suspecting that little box operates at high temp. Could it last ?
----
The rest is algebra to me so I'm just sharing a video with you.

Let me tell you something : even with my crappy headphones I was able to perceive how good that thing sounds but you tell me if I'm right. At the same time I noticed this headphones bass is horrible and unclear. Will play around EQ Apo. The most fascinating thing about the 3D printed speakers is how the sound does not reverberates ( correct my language if inaccurate ) . It feels like every sound leaves no echo and it actually ends when was intended

---------------

Something weird is going on

 

[Ferather]

Edit, forgot the first question.

Class-D is very efficient compared to power amps (analogue), it uses less power and produces less heat. My older Z5500 had an analogue amp, and got very hot (has radiator).
The Z906 has no such radiator and remains much cooler at high volume, so the answer is, it should be cooler than normal, but we are talking low watts.

----

EQ should go onto MFX, E-APO can only be used as SFX, as MFX will replace DTS. I suggest using the EQ in the Realtek app if you have added the DTS options to the policy, it should show.
The Z906 are 3D speakers, but I only get reverb (echo) if it's in the audio, else I get position based spatial but no reverb at all, I have noticed myself.

You will be surprised how much audio these days has attempts to add 3D enhancing, I also dislike reverb.
Can't say I have noticed any reverb in games or movies, especially if its 5.1 to start with.

No offense, but artists who tune their audio based on headphones, which cannot play the full range and use less than 1w, is already doing it wrong.

Personally I am waiting for the smart speaker version, the Z906 is 11 years old, and yet to be replaced (still produced, same price).

Yeah I'm trying to get the old panel back or add some config to the UWP app. So far I just got a "DTS Sound effects" header but with no controls.

Is there use for RtkAudioUniversalService ? I can disable it , stop it and the audio works regardless and the rtk audio console works too.

 

[Ferather]

Did you register the file? I guess you did. For me if I disable the service audio goes down a little bit, but I guess it depends.

Yep. If you beat a drum in the top of the mountain and the entire village can ear it, you surely won't be able to represent that on headphones so acoustic music should always be tuned for speakers. unless it's synth music.

I know you are . Rather than audiophile you are audiophilic

I did. It is just that personal sensation that Intel's audio dsp do whatever the heck it wants with audio signal.

I have a question for you ¿is USB audio only routed differently that rca or it is processed in some other way? I want to know if the end sound is the same

 

[ajf64]

@Ferather after a ton of testing your next cost effective upgrade is the vizio elevate P series it punches so far above its price tag and the atmos and dts X support on pc is really good much better then i ever thought it would be the sound field this creates is really kinda amazing it def beats the z906 by a large margin and its future proof for at least the next 5-10 years they actually do ota updates with new decoders something you don't really see much but atm it dose everything you could want all the way up to uncompressed pure atmos and dtsX.


the feel i get from this is the same feel i got when i got my z906 that i got much more for my money then i should of. Oh and their up-mixing might be the most accurate i have seen ever the way it mixes music is damn near perfect and you can choose to have a wider sound stage or mix it for height since the speakers can rotate either up or forward.

RCA is catagorized as analoge audio tho there are some digital RCA cables but standard red and white would be analog stereo USB is digital so should suppot wider range of freqencys beyond stereo

 

[Ferather]

I re-uploaded [DTS DCH 6.0.9414.1], with the newer preset and some final changes to DTS Interactive.

@ajf64, Thanks for the info (your post above). Does it do more than legacy standard on SPDIF?

 

[Lucky8]

Oh, crap. I meant mini plug . Is mini plug output the same signal as USB ? Sorry about the mistake guys . Surely one is analog and the second digital but in terms of signal processing quality would be the same in end headphones ?



Kind alien, would you mind telling me if you have tried this ? https://github.com/xinleio/Headphones-simulate-stereo-speakers

It's EQ Apo sets .
I'm getting a lot of clipping and low volume on my headphones so I guess it is driver's half fault and crappy headphones the other half . I mean, Realtek driver not yours.
