10. Nahimic A-Volute software on the PC causes crashes and unexpected behavior

If you have this on your computer, remove it immediately. Many sources report this as malware too. We have seen this recently on another user's computer and it was the cause of issues.

New MSI motherboards (including Z890) ship with Realtek audio drivers bundled with Nahimic / A-Volute enhancements, even if the user never knowingly installed Nahimic.

These modules inject themselves into every audio process, including DAWs and audio plugins/hosts. MP Host is an audio-real-time application, so these DLL injections can easily cause:

  • startup crashes

  • random crashes when loading plugins

  • UI freezes

  • high CPU spikes

  • audio engine instability

MSI motherboards systems nearly always have A-Volute/Nahimic active

Even if you do not see “Nahimic” installed, MSI bundles it silently inside the Realtek Audio Console, and it still loads the DLLs.

I have seen multiple crash logs where NahimicOSD.dll injects into audio processes and triggers a crash in:

  • JUCE-based apps

  • VST hosts

  • Audio processing threads

MP Host is especially sensitive to such injections.

If you open Windows Services you will see if there is a Nahimic service running.
and check C:\ProgramData\A-Volute\ if it exists.

Disable the Nahimic service
Run PowerShell (run as Admin):  
  
sc stop NahimicService
sc config NahimicService start= disabled
sc stop AVoluteService
sc config AVoluteService start= disabled

rename or delete if you can these folders:
C:\ProgramData\A-Volute\
C:\Program Files\A-Volute\
Uninstall the A-Volute / Nahimic components

In Apps & Features, uninstall any of the following:

  • Nahimic

  • MSI Sound Tune

  • A-Volute Audio Effects

  • Sonic Studio 3

  • Realtek Audio Console (with Nahimic extension)

Then reinstall Realtek drivers WITHOUT Nahimic.
