Last Monday I purchased and installed DDMF Virtual Audio Recorder.
I had to disable Windows' Core Isolation Memory Integrity to install it, and figured I could re-enable that after installing.
Sadly, that isn't the case.
My email to DDMF support remains unanswered.
I found a way to uninstall part of Virtual Audio Recorder here:
https://answers.microsoft.com/en-us/win ... bcd044fcef
Sadly, there's a 2nd driver I cannot find in Windows Device Manager - Devices By Driver.
Windows reports it as "DDMFaudio.sys Driver version: 1.20.0.0 Product name: Virtual Audio Stream" (that file is indeed present in System32/drivers).
So I'm stuck. Can anyone help me out please? Thanks!
Cannot turn Windows Core Isolation back on after installing DDMF Virtual Audio Recorder

Thanks WackyZoundz, I appreciate it.
Very helpful, but I haven't been able to fix the problem yet.
I'll wait a little longer for DDMF to hopefully reply to my email.
Perhaps your link will show a way out for other people though, if they stumble upon this thread.

I tried the things listed below, but couldn't find the Published Name.
- I had already tried Device Manager - Show Hidden Device, no luck
- pnputil /enum-drivers
doesn't seem to list DDMF/VAR/Virtual Audio Recorder
- dism /online /get-drivers /format:table
throws an error; the log file doesn't seem to mention DDMF/VAR/Virtual Audio Recorder
- pnputil /enum-devices /disconnected
doesn't seem to list DDMF/VAR/Virtual Audio Recorder
- Get-WmiObject Win32_PnPSignedDriver | select DeviceName,InfName (PowerShell)
doesn't seem to list DDMF/VAR/Virtual Audio Recorder
- Get-WmiObject Win32_PnPSignedDriver | select DeviceName,InfName, FileName (PowerShell)
A column FileName is added to the list, no entries though
I didn't try this:
"If you cannot uninstall the driver from the online Windows image, you can try uninstalling it from an offline image"
...cause I don't know if that is the way to go forward.

You can also use Sysinternals Autoruns to take a look at what is loaded during startup: https://learn.microsoft.com/en-us/sysin ... s/autoruns
As soon as you know the filename of the driver you can use the Windows registry editor to search and delete the driver's entry which should stop it from starting.

I can recommend the entire Sysinternals Suite in general for every Windows user. It's one of the best tool collections for fixing numerous problems. It also comes with an alternative to the Task Manager (Process Explorer) which reveals a lot more information about what is running.

Thanks again WackyZoundz, I didn't realize Autoruns shows drivers, too.
I had already found the driver's file name by clicking Windows Core Isolation - Review incompatible drivers though (if anyone stumbles upon this thread and wonders, that link is only shown after any failed attempt to enable Memory Integrity).
If my support request to DDMF remains unanswered I will brave the Registry (thanks for that suggestion, it's a relief to have that final recourse
).

Don't forget to make a restore point before deleting the driver entries in the registry. There will be several entries depending on how DDMF wrote the driver. It's also possible that there are a few more files left to remove.

Phew, DDMF got back to me (apologizing for the late reply, so I suppose they usually do not take this long to respond).
I trust they will help me uninstall VAR.
DDMF is "trying to get an update published asap but Microsoft have considerably increased the demands on new drivers that they accept, so that might take some time".
For the time being, one has "to choose between using Core Isolation or using" these drivers.
Thanks again, WackyZoundz, I was stressed out over this issue and the info you posted eased my mind, showing that there had to be a way out.

I'm curious: Have you tried VB-Audio Virtual Audio Cable (https://vb-audio.com/Cable/index.htm)? This might work as an alternative to DDMF's Virtual Audio Recorder.

The product you mentioned is called VB-Cable or VB-Audio Virtual Cable. Virtual Audio Cable (VAC) (https://vac.muzychenko.net) is a different one. Please don't confuse them.

No I haven't - I'll stick to Voxengo Recorder for the time being ('just' a plugin though).WackyZoundz wrote: Tue Sep 03, 2024 10:50 pm I'm curious: Have you tried VB-Audio Virtual Audio Cable (https://vb-audio.com/Cable/index.htm)? This might work as an alternative to DDMF's Virtual Audio Recorder.
Thanks for suggesting that alternative though (I had never heard of it).

Were you able to solve the issue in the meantime?

Sorry, I didn't notice your reply until now.
Yes I was: DDMF told me to boot in Safe Mode, then delete DDMFaudio.sys from System32/drivers.
(I didn't bother to mess with the Registry)
