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

[canucker]

1st pic is audio coming from speakers-as well as headphones
2nd pic is choosing headphones from sound icon on taskbar-you can see the audio playing but no sound from phones
this is on a fresh reinstall-would choosing the A option instead of main during install fix this perhaps??

It might do, it should be hardware circuiting though. It might be that the CFG this driver comes with is not suitable for the 1220 P. Can't say I have seen many P versions.

If not I can take a look via RustDesk maybe tomorrow or during the week.

----

The default mode, works like a splitter cable. Most devices will have an 8+2 DAC and 8+2 Amp, when its splitting, its using the speaker out and splitting after the amp.
When its in separate mode, the extra +2 in the DAC and Amp are active and used, and the splitter is turned off, this is done in hardware.

The CFG in the driver .inf file, is what should be controlling the hardware, so if the CFG is missing, the feature wont work.

is there a specific cfg file to look for within a specific inf file,which i am thinking is within the driver folder of the install package

 

[Ferather]

Its actually quite difficult, even more so for me as I don't have the device in question. I can get the CFG from your native driver, but its trial and error to find the right one(s).
The CFG this driver comes with is from Asus (MoKiChU), and with DTS, however the drivers are not specially for Asus, just comes with their CFG.



The CFG supports nearly all devices.

====

As a last resort, you can install your native driver (after removing this one), then use my other pack to add DTS:X to that driver.
You can use the .reg files from 'DTS Settings' instead of the ones provided in that pack, for Realtek+DTS.

Note that 'DTS Settings' is for Realtek HDA not USB, if anyone else is reading this.

 

[canucker]

whew,a lot of this is over my head,not ashamed to admit that
also i truly appreciate your guidance and help
the reg files within dts settings
there are these 4
misc-clean listen and equalizer apo
multichannel
multichannel-interactive
stereo
all would be merged other than the equalizer apo-if not using
is that correct?

oh mm sorry i try changes sometime to this problem,so this cause for this new nambe for driver, so also try add codes for my drivers and i try again not working also I try this solution is fail, I'm sorry for not saying that part @Ferather ,this LEN LEGION 5 17ACH6 my device, I appreciate it for help

 

[Ferather]

@canucker, you want the multichannel, multichannel-interactive, stereo ones, to replace the ones provided with the ultra pack. This way you get Realtek+DTS, rather than just DTS.

 

[canucker]

I am at a loss,on getting those damn headphones to play back separately
clean install following instructions exactly
something i noticed in the realtek panel
-speakers i can only select stereo-5.1 does not work
however i play a 5.1 test file and it will play that test properly through speakers-and the headphones
of course playback at the same time.
i merged those files you replied about and no difference

 

[Ferather]

So you are using the normal driver your Realtek uses? If you are using the normal driver for your device and Win10, there is something not right with the device policy.
The native driver for the device most certainly should have the right CFG. Message me a good time for RustDesk, GMT 5-6 PM is likely (weekday).

I have an export of my S1220A policy, there is some chance it fixes the issue. In the past it's fixed passthrough with MSI devices.

====

One other thing you can try, is remove everything Realtek audio, and use the default Microsoft one, this will bypass the device policy entirely.
You should get separate speakers and headphones by default, check with those. If it works, its the policy that's the issue.

If that works for you, and you are happy enough to use Microsoft, you can add DTS using the .reg files that are provided (no Realtek).

 

[canucker]

Hi Ferather.
driver i am using is what is inside your folder
your s1220a policy-which is in your download folder?if i do that-i would follow the guide in that folder correct?
Some progress-i uninstalled the realtek and yes i can hear the headphones now-i have to choose speaker within the sound applet and audio plays from the phones
to hear audio from speakers i choose spdif
regards merging the reg files-still the same ones you mentioned previous post?
Update on merging the .reg files,it did not enable dts!!

 

[Ferather]

I will assist you via RustDesk on the weekend. There may be some confusion. Message me a good time after 12PM (GMT) either Saturday or Sunday.

I might also be available this evening.

 

[Ferather]

As a reminder (was helping someone else the other day), make sure your digital receiver supports DTS before using this driver for SPDIF.
An additional side note, a proper digital Class-D system should have no DAC, it will also be 48 bit ~200 Mhz.

----

If you use Edge browser, you will get 5.1 natively (test links in post 1), other browsers may not support multichannel.

====

Hopefully soon we will get RGB Optical or similar, and can do 256 bit 200 Mhz from the source (no pseudo, generated samples or bits).

Below are images of a PCM or PAM based input (RGB), in PAM mode the source data moves the speaker(s) directly.
In PCM mode (all current devices), the main unit will generate additional samples, and bits.

One bit (colour pulse) transmission, means the bitrate is the sample rate, x number of channels (or just the rate if one speaker).
For example, 1 speaker output at 200 Ms/s would need 200 Mbits/s per second of RGB Optical (1 bit x rate).




10 total channels RGB Optical, 256 bit @ 200 Ms/s = [2 Gbits/s].
10 total channels PCM, 256 bit @ 200 Ms/s = [512 Gbits/s].


The above illustrations are simplified.

 

[Ferather]

Here is a simplified multichannel RGB Optical input, each channel bit is pulled from the sample, and routed directly to the relevant speaker as one stream.
In this example, white and off are reserved, off means no data (0 volts), white is the sample packet (not sent to any speaker).



This example is two samples of 8 channels, 18 total bits sent.

----

No specific set channel, bit depth or sample rate limits set by RGB Optical, its limited by bandwidth and-or processing ability.
The bit depth can go as high as the number of colours available (ex reserved), 256 colours = 256 bit.

 

[Ferather]

DMAS = Digitally Managed Audio System

The main specifications for the DMAS unit and speaker is the PAM level, sample rate (samples per second) and maximum power available (main unit supply).

RGB Optical does not specify a maximum decibel for the highest bit (bit 256), instead the speaker uses its own set max volts.
It should also be the case that if you do not like the sound quality, the only part to change is the speaker.

A speaker can run on an external power supply, using signal only from the main unit.


No demodulator, no amp. PAM from source at a high enough rate its basically AC, and all [original] information.

----

Here is a simplified illustration of microphone (source) to speaker (output) in RGB Optical.

[Ferather]

RBG Optical cable, and additional violet, note that ultraviolet and infrared can also be used. These are broadband cables, but there could easily be a DMAS cable.



----

Note RGB Optical would also replace HDMI and DP as video connections. A cable can have one video lane and one audio.
My version of RGB Optical is PAM X, so it applies to anything currently using PAM technology.

[Ferather]

RGB Optical is post digital age, there is no binary, optical age would be more accurate. The amount of binary needed to address one switch, or outcome, is a lot.
There is no compression, and there should be no ability to apply any, since you can get less than 1 bit per switch, outcome, other.

It should also be the case of storing RGB pulses would be smaller in size compared to PCM (even compressed).
In addition, your home fiber broadband would be so fast, compression is a bit pointless.

----

Imagine a replacement to HDMI or DP, which can transfer 300+ tera bits per second (300+ Tbits/s).
