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

recently upgraded to windows 11 and just want to say driver seem to be working just fine no issues or changes
 
Post 1 updated, thank you moderators. Reminder, I don't make DTS technology, I am a package provider-signer, buy a DTS license (Sound Unbound), its valid on 10 devices.
Note: Digital output devices (HDMI, SPDIF) still needs the switch trick for stereo, in order to enter 'Speaker' or 'Headphone' mode, (more info here).

@leveltrauma, DTS_EFX and DTS51_EFX, uses different technology, EFX51 and the 51 system is multichannel (5.1 is considered the min).

Edit: I forgot the respond to the sample rate on SPDIF, yes its a bit bugged with Windows as you mentioned after reading my message.
Even my Z906 can do 192khz x 2, which is 9.22mbps, its just the test file fails to play, unless its specific drivers as you said.

If I send 192khz and set SPDIF to 192khz, I get 192khz, so ignore the test file no play bug.

Install options

> Main: DTS Interactive on SPDIF (5.1 with 7.1 processing).
> Alternative: 2 channel SPDIF (chip parameters).

If anyone tells you SPDIF cannot do XYZ, compared to HDMI you send them to me!

SPDIF (ALC 889) and HDMI 1.4 (AMD R7), maximum aggregate samples:

Note: 8 x 96khz is 768khz total, which can be achieved.

HDMI 2.0+ and 7.1 analogue (ALC 889):

Same total samples as above, but now with more bits.

Updated Potplayer preset here, for anyone using it.

Tried your prayed Pot-player ( + Preset ) because I like the info or stats page. It is uncomfortable in MPC:BE to navigate to the filter section. The hotkey is not very useful too.
Well, with Pot-Player and playing/upmixing audio the result is really crap.
Hell it looks like I'm marriage with MPC:BE which does a good job all the time. Even if the filter output Tabs are a bit confusing.
But anyway you've got a great result with your software :pimp:

I don't use the upmix option, I hate expand, so noisy. I use Equalizer APO to upmix.

I think I know what you mean - I got this distorted sound in the past / or If Interactive is disabled then in the Multichannel Mode the empty channels get in wrong way filled up i.e. FL + FR > upmixed by itself = noise distorted and overturn sound

EDIT:
[...] but with this solution it sounds great!

What is this "KS_Speaker Mode to FORMAT_DTS" ?
 
Turns out the 1152 was due to a decoder, although I am not sure why. I tried a TrueHD 7.1 trailer, decoded and set to 8x 192khz, and DTS-HD MA 11.1 trailer, decoded and set to 8x 192khz.
Both produced noise unless I reduced to 8x 96khz or 6x 192khz, both decoded to PCM, however other DTS-HD MA trailers work @ 8 x 192khz.

I Think it has something to do with the stream itself or maybe with "speaker system"
Ferather is working with the String {e48......}/3 for Interactive Mode. This one is a OEM Defined Extensible Wave String. Multiple channel audio data and WAVE files

I only played a little bit and with the earlier linked winaudiotest tool I got that information that the SPDIF run's only in the Channel Mask for Stereo.
Something which I have changed results in the Channel Mask of 51SPEAKER_PCM.
The other AudioEngineDeviceFormat Strings did not change.

I'm no specialist - I have no idea if that behavior change the Audio Playback or whatever.
To many Registry Keys and to much Microsoft Docs.
Ferather mentioned earlier it's a bit tricky to setup the right GUID for getting i.e. 10 channel Sound. I thought to find the right combination: dwChannelMask+Subformat+SampleRate+Bits of Precision = valid GUID could be a step in the right direction.

Only in theory
 
Well HDMI sample aggregate is confusing me, HDMI 2.0 specifies 1536khz, and the rest are below, with 1.4 at 768khz, but now I am reading that's 768 x 2.

My question would be, why would bitstreaming use PCM aggregates, when its encoded?

Now it's starting to get interesting since I have found a way of running ASIO at 1536khz!
 
1536khz has been around since analogue could do 7.1. No idea why it took so long for HDMI to get it. The good news is SPDIF really is equal to HDMI 1.4.
For HDMI 32 channels (as far as I understand), that's 1536 / 32 = 48khz a channel, which can be done with any device to be honest.

For SPDIF-HDMI 1.4, that would be 768 / 16 = 48khz a channel. 99.99% chance you need to bitstream above 8 channels.

Hi, I've been trying to install this on my Lenovo Legion 5 Pro. I've followed the installation instructions, but it doesn't seem like it installed properly. I can provide more information if needed. Thanks in advance!

The 'Realtek(R) Audio' should say 'DTS DCH', what is the Realtek chip? I also see Nahimic, you might need my other pack.

I made the package so that it can be added to any driver, or to the system in general, you will need to program where the driver normally would.
Once you have read and understand the posts, you can apply the settings to almost any device.

Reminder: I dont make DTS technology, DTS do, if you want to part with some money, buy a Sound Unbound license.

What's your time zone btw? In case I have some questions during installation. I'll be home in about 10 hours.
 
You are very welcome, its nice to see an ALC 2XX working 100% like my ALC 889. Nice chip.
