Stereo mix may not be a feature supported by his ALC, for my ALC889 its listed in the motherboard manual, along with DTS and DD info.
It's there every time I install drivers. hopefully Hearick's info will give this option. ALC889 competes with X-Fi.

@Glebo

12XX series might be a problem, I got a few messages with BSOD with 12XX and AMD.
I have made changes but cannot confirm it works on 12XX.

Make a backup and-or restore, in case not.

----

Below I attached the original ID's used in the source driver. Even unlisted it can work (my ALC889 is not listed).

I don't think so, see this image is from the previous restore point:

I did a clean install and the "Stereo Mix" option disappeared.

DTS:X supports lossless encoding for the highest audio quality possible. Although in situations where bitrate is of high concern (24.5 Mbps), DTS:X can also operate in a high-quality lossy mode. DTS:X supports up to 96k for object mixes but can still support up to 192k for stereo and multi-channel mixes. Instead of being encoded into the Blu-ray disc (like DTS:X), Virtual:X is a post-processing technology that aims to create the effect of a 7.1. 4 surround set up (that's 11.1 channels, including four height channels) through a soundbar or standard 5.1 speaker system.

Great job there...
I'd really thought, i wouldnt ever experience this with my Realtek & Z906. Thanks...
It keeps getting better and better.
I appreciate your works here....

Optional Update:

DTS DCH 6.0.9116.10 (UAD, Signed) - | Guide here | Make a restore point in case your device is not supported.
  • Set APO4 to use multithreading, thread settings changed from "both" and "apartment" to "free".
  • Performance has improved slightly, changing presets is more obvious.
I still suggest using E-APO for upmixing and slightly better performance. (see below).

Note: As of version DTS DCH 6.0.9116.8 you no longer need to clean your registry after uninstalling.

Apps here: MediaFire

Any idea if APO uses SIMD (AVX256) for acceleration?

I believe the main audio processing is done by an audio processor, whereas third party APO's, features or software could use the main CPU, especially if the audio processor is not enough.
You wont notice any performance issue with APO's or other features using the CPU, it shouldn't go very high maybe 1-2% depending on your CPU.

By audio processor you mean the Realtek chip? Because that doesn't have a DSP.

I think only Intel has a DSP, but it's mainly for voice recognition. And AMD used to have TrueAudio.

I just want to know more about the modern PC audio stack, that's all. All the known PC audio chipsets (ALC 8xx/9xx/1xxx) lack a DSP, AFAIK.

Hi @Ferather ,

I am trying to unlock multichannel mode (5.1,7.1) but I am having BSODs on Windows after doing this. Any suggestion?

That would be because your ALC275 is probably stereo only, ALC275 Datasheet, PDF - Alldatasheet, those options shouldn't show, that might be to do with the ALC892 change I made.

I officially only support 8XX series, not so much stereo only ALCs, I apologize.

Maybe it's true for this one (premium series), but for ALC8xx/9xx I haven't found anything, so I assume the Realtek driver must use CPU SIMD (SSE/AVX) for audio processing.

I don't know if you were a PC gamer 20 years ago, but we used to have dedicated audio DSPs back then (Creative EMU10K + EAX) with zero CPU usage. The WinXP audio stack was also a lot simpler and it supported DirectSound3D (no longer possible).

My old Creative X-Fi did use CPU for analogue to digital transcoding, up to 10% of the CPU, very inefficient. Not sure what else it used the CPU for but 10% is a ton.

Currently my Realtek 889, with transcoding, Ultra and E-APO hits 4% CPU (+- 2% for Windows), same system.

Here I have a media player, discord, a game and steam running, all at once:

Update to 6.0.9126.1 soon, and new thread.

Strange, I always managed to use it normally. No BSODs with other drivers. To make the transition to the HDMI / Receiver correctly, I need do unblock this.

Hmm, it worked ok on other versions of DTS DCH? I can remove the code, but would rather not due to ALC892. I can remove the code for you specifically, if you can confirm it was ok before DTS DCH 6.0.9116.8.

Hi @Ferather - I just found your drivers and had some issues installing them on my ALC1220 -
HDAUDIO\FUNC_01&VEN_10EC&DEV_1220&SUBSYS_1462CC35&REV_1001 - [I was able to manually install the driver using a combination of installing the certificate in the trusted root certification authority store, and using have-disk method to install the DCH driver]. However I'm not seeing any DTS apps or tabs in the sound properties unfortunately. I'd also like to help you with a powershell script/installer instead of a batch file so it works a bit more seamlessly for non-technical folks. Let me know if there's anything I can do to help get this working on my ALC1220 for you. In the meantime I'm reverting back to AFF Optimus. Cheers

"However I'm not seeing any DTS apps or tabs in the sound properties unfortunately" you need to install the apps, and if you want the Connect panel you need to add the property key.

New thread made, and update. https://www.techpowerup.com/forums/threads/dts-dch-driver-for-realtek.279972/

Main driver is the normal one, but without the ALC892 edits, Alternative is for ALC892 and others.
