Automatically sets the affinity of "audiodg.exe" to only one core on computer start to fix the crackling noises that can occur in VoiceMeeter.

New in v2

I learned about Windows Task Scheduler that allows to run the script in a way that does not open an admin prompt on every login and wrote a new script that makes use of that.

Note: If you had v1 of the script installed, it is automatically uninstalled if you install v2.

How to Install

To install the script, download the install.bat file from the latest release and run it. That's it!

How to Uninstall

If you no longer want the audiodg affinity to be set at login, run the following command from an administrator command prompt:

schtasks /delete /f /tn audiodg-affinity

The Problem

Some users of the program VoiceMeeter have a problem with a sound channel having crackling noises. This can be fixed by setting the affinity of the windows process audiodg.exe to only one core. This, however can not be done persistently in Windows itself, so a common solution is to use Process Lasso. My problem with this solution was that the free version of this program asks to buy the paid version on every boot and constantly runs in the background although the only feature I use does not require that. This is why I decided to write a simple script that is run once on system boot and changes the affinity of audiodg to only one core.

voicemeeter-auto-affinity's Issues

This made crackling worse for me

This seems to set the affinity to only core 0 but that's an SMT/HT thread for me, and I need more than one core selected as my 1950x doesn't have very high single-core performance. Using process lasso with Disable SMT and manually disabling the last 8 cores on the secondary cpu package and setting process priority to high solved it for me.

not working

After installing, I tried to run set-audiodg-affinity.vbs to see if it's going to work. but it didn't

Power Condition should be removed for it to work more consistently with portable devices

Portable devices won't be on AC Power upon turning on all the time, so this will be really helpful.

V2

I downloaded v2 and after install and reboot it does not show affinity set to 1 cpu it has all selected still. Not sure if its my machine or the bat file. Installed as admi as well.

VBS script not working on some Windows installations

I run it. CMD pops up asking Y/N, I put Y then enter.
Seems all good. Next time i run my PC, nothing happens. Affinity isn't changed.
