Turn off Windows audio sleep

My Dekstop-PC runs Windows 11.

I have the problem that Windows puts audio devices in some sort of sleep mode after a few seconds of inactivity. Now if a sound is played its takes about half a second to wake up. I dont want that the sound driver goes into sleep mode.

I am running the latest Windows Driver are up and running I use an external DAC/AMP via USB UAC 2.0 I know for a fact that Windows is the culprit I already tried: -updating/reinstalling drivers -changing powerplan -trying another audio device -changing Keys in the registry (only problem there are multiple power settings) and on adress 0005 which is my external DAC/AMP doesnt have these settings. (screenshot attached)

My question is how can I turn this off globaly (or just for my DAC/AMP) and why is this enabled in the first place?

Thanks in advance

Hi Paul,

Since your DAC’s driver package doesn’t include any power‑state controls the next practical step is to disable Windows’ automatic device power management at the system level. Many Windows 11 users run into the same issue with external DACs and USB speakers dropping into low‑power mode and this approach has proven to be the most reliable workaround.

Windows 11 tends to re‑enable the “Allow the computer to turn off this device to save power” setting even after you manually disable it. One of the more effective global fixes shared and verified by the Cantabile community is to use a PowerShell command that switches off power management for all devices that Windows is allowed to suspend. Users have reported that running this command especially at each login stops USB audio devices from powering down unexpectedly.

To apply it open PowerShell with administrative permissions and run the following:

PowerShellSet-CimInstance -Query "SELECT InstanceName FROM MSPower_DeviceEnable WHERE (Enable = True)" -Namespace root\WMI -Property @{Enable = $false}Show more lines

This instructs Windows to stop placing devices into low‑power mode which includes your USB DAC. If you want this change to persist even when Windows updates reset some settings you can set it up as a scheduled task that runs at login. Use powershell.exe as the program and pass the same command via the -ExecutionPolicy Bypass -Command argument so the fix automatically reapplies every time you sign in.

Best regards,

Marcelo

    I dug a bit deeper into the registry and I could change it so that it does not go to sleep.

    Thanks for your reply anyway

    Hello Paul,

    Thank you for reaching out about your concern with audio devices entering sleep mode on Windows 11 I understand that you are experiencing delays when your external DAC/AMP wakes up after a few seconds of inactivity. I know how frustrating it can be when audio playback is interrupted by latency especially when you expect seamless performance from your setup. Windows manages audio device power states to conserve energy which is why your DAC/AMP enters a low‑power mode after inactivity.

    At this time there is no global option to disable audio sleep for all devices. The most effective steps are ensuring you are on the latest drivers from your DAC/AMP manufacturer, confirming your power plan is set to High Performance and checking if your device’s driver package includes advanced power management options. Some users attempt registry modifications but these are not officially supported and may not apply to all devices.

    Could you confirm if your DAC/AMP manufacturer provides a custom driver or utility that allows you to manage power states directly.

    I hope this answer is helpful if you have further questions feel free to reply back

    Regards,

    Marcelo
