To programmatically disable or enable audio hardware acceleration in Windows 11, you can modify the relevant registry settings using PowerShell scripts. Windows does not provide a direct API for toggling audio hardware acceleration, but this can be accomplished by editing the registry. Specifically, you need to adjust settings under the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class
key. For example, to disable audio hardware acceleration, you would set the DisableHWAcceleration
DWORD value to 1
. Conversely, to enable it, you set this value to 0
. Here's how you can do this with PowerShell: To disable hardware acceleration, use the script Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\Class\{4d36e96c-e325-11ce-bfc1-08002be10318}\0000" -Name "DisableHWAcceleration" -Value 1
followed by Restart-Service -Name "Audiosrv"
to restart the Windows Audio service. To enable hardware acceleration, change the value to 0
with Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\Class\{4d36e96c-e325-11ce-bfc1-08002be10318}\0000" -Name "DisableHWAcceleration" -Value 0
and again restart the audio service. Always back up the registry before making changes to avoid potential issues.
