Making Audio Enhancers Work on Windows

@alanfox2000 I noticed here that you use version 1.3.4.0 of A-Volute APO4, and it is marked as "Unworkable". You can downgrade to version 1.2.2.0 of A-Volute APO4, this is fully functional. I also had problems with version 1.3.4.0. It's just a tip.

Regarding the failure to start the Dolby service, the solution is to copy ALL the XML and configuration files to the service directory (%SystemRoot%\System32\dolbyaposvc), BUT it is also mandatory to copy an XML file called Default.xml . Following these recommendations, the service will start up correctly.

Nahimic APO 4 is design for HWID start with INTELAUDIO. I cannot test it since my MB is audio chips start with HDAUDIO.
Doesn't have Dolby service problem, just found out the newer XML version from ASUS realtek driver using DolbyAPOv2100.dll. (SFX APO)
Tested the SFX Effects surround, dialogue, volume leveler not appiled using newer XML version.
 
Yeah dolby sound effect doesn't work for both 3.2.0 xml/3.3.3 xml for some reason. Especially when I put default.xml in the main folder
I am sure you know by now since you removed Dolby XML 3.2 / 3.3 Product Config
I upload Dolby_Profiles_09012020.rar and update Dolby installation instruction. It should 100% work anyway

My machine's Realtek onboard audio chip also has the HDAUDIO enumerator, but still, the A-Volute APO4 works perfectly.

Hello guys,
I have a [quite noob] question - just replaced SPDIF connection of my PC (W10 1903 build 18362) to AV with an HDMI cable hence all trustworthy enhancements from Alan don't work anymore as the current output device is not Realtek but AMD video card.
I am halfway through installing APO driver and realize that I don't fully understand which modules do I actually need.
Normally I use EQ and "speaker fill" to upmix music from 2.0 to 5.1 which was previously accomplished by some combination of Dolby Atmos and Nahimic from Alan's pack.
Considering that HDMI connection is not encoded by either Dolby or DTS and is in fact just a bunch of uncompressed PCM channels, I guess none of the above would do the trick?
Please advise which modules are "must have" for the first try so that I start with those. Your help is much appreciated.

I clean installed APO Driver 2.7.9 and used the Dolby_Profiles_09012020.rar XML preset andcdolby apo wrapper config and the sound effect just doesn't work, playing from netflix, youtube, chrome, etc. (Intel display audio)
It all runs probably expect Dolby effect.

Believe me, I want really want it to work.

Can't be a issue with my PC if previous APO Driver 2.7.7 has the sound effect of Dolby Atmos using HDMI. Just hoping for new APO Driver to work with new files

@Jayce, the effects not appiled may caused by HDMI.
Since Dolby UWP APO is design for 3.5mm jack, HDMI may have problem
I don't have any device that can connect with HDMI cable to do a testing.

You may do a test for your Intel Display Audio :
APO Driver 2.7.9 -> Apo Wrapper ->

Install "Dolby Atmos" app for sound effects test
then try setting Composite Steam FX APO to different Dolby APO SFX GUID & use different XML version combination

Dolby APO SFX GUID
{D9916FA0-99F7-11E7-BF21-6C0B849889E1}
{D9916F9F-99F7-11E7-BF21-6C0B849889E1} < for Gaming
{EFC7A7B3-40A7-4601-ABC1-878CD5EAE544}

Hello, Dolby was working perfectly until this new version. I can't make it working. I clean installed APO driver and updated VisualCppRedist, copied new profile to %SystemRoot%\System32\dolbyaposvc. Dolby is turned on but not processing it. Can you pleases tell me what I'm missing?

Yeah, I been having the same exact problem. It was working fine in APO Driver 2.7.7 but after hasn't worked properly. I been trying to let @alanfox2000 know so he can fix it. I told him it wasn't an issue from my end because it worked perfectly before APO Drivers 2.7.8 and 2.7.9.

I did every troubleshooting methods known to man. I ruled out the possibility of it being a problem from my end

It has to be an issue with the new dlls coding or not properly configurated with the rest of the files, it needs to be done properly.

It doesn't work with your file, because this file was already present in dolbyaposvc folder for APO Driver 2.7.9, you didn't read my post properly.I said did every troubleshooting methods I could do known to man to rule out any possibility it was a issue on my end, which it isn't. I said that Dolby service runs properly but no sound effect processing is working!! (Clean installed Dolby as well and no sound)
APO driver 2.7.9 just needs to be fixed.
I know for sure because 2.7.7 is last working APO Driver with Dolby Atmos processing effect works

Even alanfox2000 seems to have acknowledged that there's a issue with dlls which is causing the effect not working or not working for long.

@alanfox2000 will XMLs 3.2.1, 3.3.1, 3.4.2 and 3.4.1 be the XMLs versions to replace 3.2.0 and 3.3.0 versions for all Dolby UWP apps?

I copied Default_settings.xml to folder C:\Windows\System32\dolbyaposvc and added from the archive Dolby_Profiles_09012020 from the folder DolbyAtmosSpeakerSystemforGaming profile and then rebooted the PC. Then again via FX Configurator I activated Dolby DAX3 UWP (APO Wrapper) on the active output and everything works fine for me. I don't see any crashes or outages.
 
For Those who was experiencing delay using Dolby Digital Live via HDMI ARC. the LG's TVS has some problem with dolby. The only way is with DTS

Dolby Forums
Reddit About
 
The problem with DTS is if you let the PC idle for a while when you want to use it gives this error as mentioned in other replies: "Audio enhancements for this device have been disabled."

Yes, with me is the same thing. I Only wish that DTS has some enhancements like the dolby home theater, the voice in games are low and the effects are loud. Before with loudness equalization i can resolve this.

Hi All. I have the same issue as Jayce.
Dolby APO3 stopped working for me - when you click on profiles in UWP app (Dolby Atmos Speaker System for Gaming 3.20703.732) or switch it off completely nothing changes in terms of sound (no sound effect processing is working). Seems happened after I installed APO driver 2.7.9. Used Dolby_Profiles_09012020. Tried also to stop APO service, copy newer dolby software components from the post above from Alan Finote and start APO service - no luck. Just sound volume level increased when you apply Dolby APO3 via product config tool. If you uninstal APO driver completely and restart PC sound volume level is decreased again to the original level. So seems Dolby APO3 only works for the volume sound boost and that is it.
 
Jayce and AlanFox2000, Use this, signed by WHQL.

v3.20700.725.0 of Dolby SWC component is included in the 9008.1 Realtek UAD Lenovo driver :)

try downgrading the Dolby Atmos app from 3.20703.732 to an older version (meaning remove the existing app and install an older one like 3.20700.702.0)

I'm not using the 3.20703.732 version yet and using an older version

Dolby Atmos for Gaming app has slightly lesser options (fewer custom profiles) than with the Dolby Audio Premium & Dolby Atmos (non-gaming) apps

Have you tried APO Driver 2.7.9 with Atmos, if so how did it go for you since there's no sound effect processing?
