Realtek Modded Audio Driver for Windows 10/11 - Only for HDAUDIO

[Jetpoet]

Device: Digital S/PDIF Optical Output (AAF DCH Optimus Sound)
Mix format: 192000 Hz / 32-bit float / 8 channels (0x63F)
Sending stream: 192000 Hz / 32-bit float / 8 channels (0x63F)

32-bit float and 192khz over digital, no no no. 24bit 48Hz.

I felt the culprit was this.... So what should I do to corret this?

Sorry I use Potplayer (see below), I've never used foobar2000, I found this post though, you need a plugin for it.

Direct sound is dead anything using Directsound uses emulation which means the apos wont get applied
use WASAPI

 

[Ferather]

It has Directsound, WaveOut and WASAPI. All sound enhancers work when using DirectSound for me, including E-APO and Realtek APO.
I also don't know very many Win games that use WaveOut and/or WASAPI, most are DirectSound as far as I know.

your information is a bit out of date
directsound died completely with windows vista its dead unsupported nothing uses it anymore hasn't for years the options are provided for compatibility ALL Dsound methods are simply a emulated WASAP session

Guys, if I use WASAPI I lose all the enhancements that Realtek DCH Modded Audio Driver gave me.

foobar2000 worked perfectly before installing Realtek DCH Modded Audio Driver, and I used DirectSound/Digital S/PDIF Optical Output... So I don't get it... Why did it work before and why did it stop now? And why does it work again if I play a song on Youtube and then use foobar2000 again?

Isn't it weird?

PC Gaming Surround Sound Round-up (satsun.org) - Last updated 12 December 2020, XAudio2 can passthrough DirectSound (emu as you said) or WASAPI.

"WASAPI, DirectSound and MME interfaces can be considered "high-level" only in comparison to Kernel Streaming because they are built on top of KS. In modern Windows versions, these interfaces are often considered "low-level" because higher-level ones (AudioGraph, MediaCapture, MediaElement, XAudio2) are offered. Meanwhile, XAudio2 is often called "low-level" because it offers hardware-close streaming control."

"WASAPI interface has been introduced in Vista. The abbreviation stands for Windows Audio Session API. It supports both shared and exclusive access modes. In the exclusive mode, it is highly efficient like hardware-accelerated DirectSound, but in shared mode, its efficiency is comparable with shared-mode MME and DirectSound (not accelerated)."

Check if the product in question (foobar2000) supports WaveOut. I went through the same problem with VLC Media Player

Good old PCM

Yeah, I have the same problem with VLC too...

Anyway, I'm afraid foobar2000 does not support WaveOut... so I guess I will have to choose between the application and the drivers: I will have to disinstall foobar2000 or the drivers....

This seems to work for me. Even E-APO is upmixing stereo to 5.1-7.1 as normal. You will another plugin for 32 to 24 bit (if still needed).

I’m having issues trying to update to the latest version. Previously these were all working prior to uninstalling and cleaning for new version:

Realtek Audio Control Center UWP App ( ROG Version )
Dolby Atmos
THX Studio Pro Sound
DTS Interactive ( I don’t actually use SPDIF Audio on my setup so I never noticed a difference with this turned on so I just left it off )
Sonic Studio 3

After upgrading I can no longer get THX to work or show up. It installs apparently and when I attempt to reinstall the lastest update it uninstalls during the uninstall process. So I don’t know what’s going on. I have fast boot turned off and driver signatures enforcement turned off as well during the installation process. Anti-Virus is also temporarily disabled to prevent problems as well.

Also the Realtek UWP Control Panel no longer shows up as the ROG version. Reinstalling the previous version I was on does the same thing even though it worked before.

Since I don’t use SPDIF there’s no point in me installing DTS interactive and I’d like to get back all my stock ROG Realtek effects in the CP instead of having DTS I can’t use. They worked well with Sonic Studio 3 and Dolby Atmos.

Also I’ve noticed when I try to install Soundblaster ( any version other than Cinema 5 since I don’t have the required hardware for C5 to work and SB720 has worked before ) SB installs fine but when I try opening the app it loads with UI elements missing or loaded but but I can’t actually click on them to change settings. Terminating and Resetting the app via its app properties doesn’t work either. It seems to load up if my Audio in CP is set to stereo but bugs out when setting it to 5.1 or 7.1 even though those outputs work flawlessly for Sonic Studio and the Realtek App. I also noticed that if I install Sound Blaster, Dolby Atmos no longer installs at all.

I’ve tried using the KGA file with no luck as well as doing the usual cleaning with DDU and Driver Store Explorer and double checking with CCleaner.

At this point itd be nice to just get my ROG Realtek UWP CP with its effects like EQ working along with Sonic 3 and hopefully Atmos.

Sorry for the wall of text but I wanted to make it as in depth as possible going over my issues so it’s easier on the ones who will hopefully help me troubleshoot.

First of all, thanks for your support

I tried exactly as you instructed me, but still no success. I had actually tinkered with that very settings before but to no avail.

Believe me, sampling rate is not the culpirit. I thought it is, but it is not. If it was, foobar wouln't work ever. But if I do this, it works:

32-bit float and 192khz over digital, no no no. 24bit 48Hz.

There's no chance to send 7.1 through SPDIF.

Try first 5.1 @ 48kHz / 16bit.
If it's working, you could test 5.1 @ 48kHz / 24bit Dolby Digital & DTS.
Default is stereo 2.0 @ 48kHz / 24bit PCM ... up to 192kHz possible.

Try deactivating "signal improvements".

Hello. I don't think that figure is accurate. Foobar worked before installing the Realtek DCH Modded Audio Driver and I did not change any settings, so I think that crash report is actually a mess-up...
Anyway I did a post in the foobar support forum explaining the problem, let's see what the foobar guys say...

Try deactivating "signal improvements".

Wow. Wait. That's it. If I deactivate "Signal improvements" it works!

ALAS, but I loose Dolby Atmos enhancements!

Hmm very interesting, when you installed the AAF driver did you pick "both decoders" or just "dolby digital live"? You get a different Realtek APO depending on what you choose.
I chose "both", and I don't get any issues with any audio apps (plus I can use both options). My panel options are different to yours, so I guess you picked DDL.




I'm also using a newer APO version I patched (cannot go higher as both decoders), Alan will pack it in the next update
You could also try this ID fix (not E-APO), but I am not sure that it will have any effect on your problem.

Well, I actually don't remember well. I kinda remember I picked up "both decoders" but I'm not sure. What I do remember is that I did not uninstall windows stock audio drivers. So what do you advise me to do? Unistall AAF drivers and install them again?

 

[Ferather]

Do you see DTS and DDL as separate options in the dropdown for digital?

 

[Cawet_Berdarah]

this install was successful ?

 

[Romulus2K4]

After uninstalling the driver, I still have THX loading at startup, and there doesn't seem to be any entry in add remove programs to uninstall it. How can I fully uninstall THX? Thank you in advance.

 

[OneMoar]

figured out what the volume issue is had to reinstall with sonic studio enabled and then toggle smart volume on, set it to extreme
then I was able to shut it off and the volume returned to normal
weird

 

[Jetpoet]

No, only DDL

 

[leongx]

Is there a proper uninstaller for all this?
Looks like complete mess of things that get added

 

[Jetpoet]

That's what I'm scared of, that all this stuff doesn't get unistalled properly...

 

[leongx]

yeah is a bunch of seperated things to uninstall...would be nice if the main installer provided a way to uninstall everything that was installed before
