Did you get the "Voicemod Virtual Audio Device warning" when you are trying to open Voicemod?
Are you in the Windows Insider Program and are you running a Windows 11 dev build?
Do you get a warning sign on our device in the Device Manager?
Do you get a Code 39 error in our driver properties?
We would like to inform you that Microsoft decided to revoke our driver in their latest Windows Insider builds (over build number 22557). To fix this, you need to download (and install) the specific hotfix/version of Voicemod that's compatible with these early versions: https://www.voicemod.net/b2c/v2/VoicemodSetup_2.30.0.0.exe*
*Please note that the update will not be enough, as the driver is not reinstalled in that case. You have to completely uninstall Voicemod, restart Windows, and install this version.
If the error persists (actually, if you open the details you will see that it varies from Code 39 to Code 37) it is because Vanguard, Valorant's anti-cheat is disabling the driver.
- If you are not using a Beta/Dev (insider) build of Windows 11 that's over build number 22557 means that you are using version 2.30.0.0 of Voicemod. Please, update to the last Voicemod version:
https://www.voicemod.net/b2c/v2/VoicemodSetup_2.31.0.3.exe*
*Please note that the update will not be enough, as the driver is not reinstalled in that case. You have to completely uninstall Voicemod, restart Windows, and install this version. - If you are using a Beta/Dev (insider) build of Windows 11 that's over build number 22557 means we do not yet have a solution for this problem and you will need to uninstall it (either Vanguard and not play Valorant, or Voicemod).
NOTE: Riot Support answered that you should not play Valorant without Vanguard because you could get a permanent suspension on Valorant (because the anti-cheat is necessary).
We are working to make a driver compatible with the latest Windows 11 builds and Vanguard, Valorant's anti-cheat.
In the meantime, one option would be not to play Vanguard (some users report that you have to close its process in the Task Manager or even uninstall it completely) and Valorant when using Voicemod and not to use Voicemod if you play Valorant.
Vanguard launching on startup or not doesn't change anything, investigating regarding that I found out that all it does is allow or remove the icon in the taskbar but the service is still working in the background.
In any case, having the icon helps you disable Vanguard while you aren't playing Valorant and then launching Voicemod.
Right now, at least for that Windows 11 Dev version, there's no way to run Voicemod and Valorant at the same time due to Vanguard blocking it.
