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

[purplenoice]

I agree about dolby...Right now I'm busy, huh, I'm doing several things at the same time, I'm feeling a bit tired. But certainly when I find time we will discuss some topics.

Another cable, I also found a unit (which I am trying to re-find) that specified all TOSlink formats up to 13.2mb (and also a Samsung module doing 13.2 mbps).
Currently I am trying to find a 'Digital converter' for SPDIF that also specifies more than 9.2 mbps, quite difficult using Google.



P.S. Cable manufactures do have to test their cables.

----

Edit: Ignore any 24k gold and any grounding, optical does not use conductive circuit, its some up-sale.

And as I said before, GPU's can have TOSLink out, and support everything (programming).

----

Both SPDIF and HDMI are bottlenecked by HDA, and HDMI uses TMDS (see here, and here) and interleaves audio-video (can delay, or no audio at all).
HDMI audio is transmitted in the blanking intervals between video frames, the timing is dependent video resolution and pixel clock.

This is worse than SPDIF-TOSlink direct, by miles. Anyway if we did TOSLink 125mb fully in PCM 24B-48k we can do:

108 Channels, lol.

I have the Auzentech HomeTheatre HD (if you need drivers that work for Windows 10/11 - give me a holla!).

Technically its HDMI-in should only carry video.

But a bug once appeared when I was high as a kite and did some counter-intuitive measures with VoiceMeeter. I got HDMI-in working..

And managed to record a Depeche Mode sample which sounds REALLY smooth (the audio clip weirdly does only does playback on some audio players - and 2 prominent Audio Engineers got the sample, and 1 of them said it was clipping (hitting 0dB) - the other one said it did not. At least it was playing for both of them. Could also do with Creative's X-Fi "normalizer/limiter", or a combination of that and HDMI in. But I cba finding out how I did it. A lot of rerouting (VoiceMeeter MME, I think), Speakers Output playing to HDMi and then something with me going into "Recording" tab of the Sound (Devices) window.. and it just worked.


So there is something with HDMI audio and smoothness. If audio is transmitted inbetweeners framers, then maybe it explains a "necessary" smoothing process?

@Ferather - do give me a whistle if you find anything you need.

 

[purplenoice]

A very very useful guide from which you can even get some other ideas. It's worth watching, I recommend it!

[Ferather]

There is also event driven mode with WASAPI exclusive, you should also try WASAPI exclusive in general. Depending on your media player capabilities.
If you use DirectSound mode, you will be limited to a legacy standard, probably only stereo + Dolby digital-DTS Surround.

====

An unrelated post: Do you guys think these idle temps are good? It's silent enough to assassinate you.

 

[purplenoice]

Yup I prefer to use WASAPI as much as possible. DirectShow is precisely the filter that gives us the most problems in Windows as far as formats are concerned. Just to mention that I have been an insider since Win8...

 

[Ferather]

Indeed, it is, even the photos app will use DirectSound to playback digital compressed audio, with video, for example a Dolby Digital Plus video-audio file. Windows also has licenses and method of handling.
For example, Dolby Digital Plus will natively be transcoded to Dolby Digital, then sent out from HDMI-SPDIF (some HDMI's might be different in management).

Another note for OEM's and SPDIF-TOSLink, the SMI connector, up to 250 Mb/s, bi-directional. Audio return, remote control, other.

Off topic:

This is without the CPU and GPU at max, I prefer to keep things under, at least for a few years.

Even at 1.2v - 4.2 Ghz, I get 103%.

The newest SPDIF 'consumer' standard, capped by HDA, ~37mbps, and 1,536k total samples:



15 x 96k = 1,440k total aggregate, achievable.
8 x 192k = 1,536k total aggregate, normal.

 

[Ferather]

Once we get 15 channel SPDIF, we will be able to actually use the 11.1 PCM mode in the DTS:X driver, plus they can add the 15 channels.

Here is an example chip for the current consumer standard, although this one is 8 channels @ 192k.

[emanresu]

Good morning!
Can we start a petition with agrued informational facts, and send it to someone?

 

[Ferather]

Or they can hire me for a day, just kidding. The demand for it is certainly there, and the technology exists. So yes indeed we need to contact OEM's.
I guess the best way is to email your current manufacturer of your speakers, since you probably like them.

For me that's Logitech (Z906), would love to see Z910 with current standards, most likely they would do 8 channels, but ALL formats.
On the same token, you will need a device with 15 channel hardware, which would mean a new output device.

I guess it's possible to produce a discrete SPDIF only card, that has full support and drivers.

====

Here are three images of my old ALC889, where I converted it to HDMI, the tick boxes transferred as EDID, it detected 2 channels.
There is also speaker configuration, in this case 2 channel and Dolby Atmos (due to format support, tick box).

In terms of speaker system design, there is now the option of fully optical-digital right up to each driver, and a PowerDAC.

On a final note, if a speaker system supports 15 channels (input), it will still work with your 2 channel Realtek (output).
If an output device supports 15 channels, and you connect a 2 channel speaker, it will still work.

Some automatic programming or user settings might be needed, depends.

HDMI EDID is the auto part, channels and formats vary.

so i finally broke down and got a atmos set up i went with the vizio elevate 5.1.4 set up i get atmos now through dobly atmos home theater but its janky it works but some times cuts out when it switches from atmos to regular stereo or 5.1 content and due to the fact i have to run through my lg c1 i cant try dtsx since the tv wont process dts at all wont even see it even in pass though mode kinda lame but i must say dobly Mat is def sounds really good wish amd had better audio drivers for the 6900xt now i just spend my time trying to find a way to force passthough of dts though my C1 if only the elevate had full hdmi 2.1 ports and not just e-arc and 2.0b

 

[Ferather]

You need to edit the EDID, I also have an AMD 6900 XT (XTX-H). I would maybe suggest skipping the LG and go for an HDMI extractor (has its own EDID) with eARC.
Any HDMI port that's 2.0 or above can do 1,536k samples, and all formats, the higher 2.1 version I believe addresses video not audio.

You could wait for a 15 channel version, by that I mean the optical, the one I has does do 8 channels though.
I have an HDV-MB01, the default specs are here, and my custom driver is here.

----

15 channel SPDIF requires 1,440k total samples @ 96k, HDMI 2.0 is needed if converted.

----



I converted the bit that drives optical to HDMI 1.4 plus more.

I think, I am the only one who has no idea what is going on.

[Ferather]

Probably because you mostly or only use stereo-analogue, not to sound rude. People have been trying to get proper SPDIF support for a long time, and people still believe its stereo only.
I was on a mission to show everyone the SPDIF-TOSlink updates that you are unaware of, and to prove the opposite of stereo only, its 15 channels now, all formats.

HDMI 2.0 vs SPDIF 2.0, well SPDIF should win, its direct without interleaved video frames, no video overheads, and its optical.




PowerDAC's utilize SPDIF-TOSlink, not yet seen one for HDMI. Smart speakers, if built properly, might be able to be rated lossless.

====

Forgot to mention, if you are using TOSlink and DTS Interactive with my driver, you can use HT mode by applying 'Multichannel [Interactive].reg', from 'DTS Settings'.

> Open 'FX Config' (Tools folder in the driver package), select the optical device from the top, then on the right press 'Copy GUID'.
> Right click the .reg file, and edit, replace BOTH '{DEVICE-ID}' with the copied GUID, then save the file.

> Finnlay in Windows sound settings, right click disable the device, apply the .reg (double click), then re-enable.

ya i have a xtx-h as well i got the power color red devil ultimate and if i skip the tv i lose vrr and 4k/120hz that i do use so i need the hdmi 2.1 port i need a minimum of 40Gbps bandwidth to run full 4k/120 with 10bit (4:4:4) HDR with VRR and LLM the elevate dose have virtual x that will processes the atmos stream in to dts:x in the sound bar but im sure pure dts:x encode would be better the e-arc input on the elevate is a 2.0b port with the 2.1 e-arc standard layered on top since that part of the standard is backward compatible i guess i could do some kinda 2.1 splitter and then spit the sound and video signal but atm 2.1 is so new i have not found one that will do this and retain all the new 2.1features since for the first time im actually able to effectively use them all with my system usually im a generation behind lol first world problems right


also it still has optical input so my next step might be to try to get it to register atmos or dts:x. Nice thing is it really lets you know when it gets a proper signal since the speakers rotate up to point at the ceiling

TOSlink, optical, digital coaxial..
Pardon my French, are there differences between optical and digital coaxial in terms of potential? If you think in terms of light, lasers, red spectrum (and hallelujah) - then Optical TOSlink (or is it TOSlink Optical) could carry infinite data? :3 just need a receiving end that can handle it.

 

[ajf64]

toslink and optical is basically the same thing just interchangeable words toslink is kinda like the brand name like all cola is coke. Coaxial on the other hand is different that uses a rca cable instead of a fiber optic cable for data transport also in theory the maximum throughput of a coaxial cable used for audio is lower then optical but optical has been limited to basically the same speed for audio transport

 

[Ferather]

Package is attached, run 'ExecTI' and run 'regedit', then file > import > New Formats.reg. You might need to disable then re-enable the device after ticking the boxes.
The change is global, and will effect all SPDIF based devices, even different soundcards, for example a Creative, Xonar, so on.

ya i ran this before on my onkyo with the z906 speakers and my z906 but didn't have all the decoders but i can run an optical and do some tests this set up should finally give us a definitive answer if its actually sending the signals since it has all the decoders up to lossless atmos and dts:X im just hoping the optical port on the elevate is of as high quality as my oynko its their highest end system so fingers crossed

Will depend on the receivers optical support, hopefully some units can be updated via firmware, if you are lucky. Would be a new unit for me.

 

[ajf64]

ya im hoping this is a bit future proof it dose get regular firmware updates so my fingers are crossed like i said its thier highest end system they make so we shall see the sound is amazing tho you should look in to it it was a super easy swap and actually less wires cant beat what you get for the price you can find it on sale for like 800$ and that gives you everything has 3 hdmi ports rare for a sound bar system so you can actually hook up alot also has hdr and dobly vision pass though def alot for your money

 

[Ferather]

Based on the previous setup for SPDIF (even my ALC889 from 2008 had it), is [2 x 192k @ 24b] on SPDIF (TOSLink, Coaxial), which is ~9.2 mbps in total.

Formats supported on a verified 9.2 mbps device: Dolby Digital, DTS Surround, Dolby Digital Plus, DTS-HD HRA, [LPCM 8 x 48k @24b].

 

[ajf64]

i mean e-arc atm is max 36mbps what im going to be interested to see if the the decoders are tied to ports or a signal is sent it will recognize it but the new standards can go up to 24/192 for 8 channels uncompressed with e-arc kinda makes no sense tho if its limited to 36mbps these standards are so all over the place dobly atmos home theater on pc will do 192/24 atmos but its app dependent different games have different quality its a variable rate bandwidth you might only have normal 5.1 at a games start menu then once you get in to game its full atmos or some might be 48/16 or 48/24 so the quality of sound you get is purely dependent on the content and it uses dobly MAT for sound processing not dobly digital plus
