  1. How to prevent audio devices from blocking computer going to sleep?


    As per image below and question above : There's no option for me to toggle whether this device can prevent my PC from going to sleep. I also don't understand why "HD Audio" is in use even though NOTHING is playing in the background. How can I resolve this? Lastly, what is a Legacy Kernel Caller? How do I know what "USB Audio Device" this is referring to? I'm on most updated win10 x64.

    :)

    PC won't sleep while playing a sound (audio driver prevent from sleep)

    Go to Control panel /and search for Power options. Select Advanced and then Change when computer sleeps. Scroll down to media settings and uncheck option "prevent sleep when sharing media" ... Names could not be exact, but you'll find them.

    Also, there is fine tutorial about preventing devices to wake computer or go to sleep..

  3. Audio device unrecognised after waking from sleep


    From time to time I wake my laptop from sleep and find that the audio driver (Conexant Venice) is no longer loaded. The audio hardware is listed in the Device Manager as just "base system device" (or two base system devices, to be precise). Rebooting fixes the problem each time, but it takes a while. Is there a quicker way to make the audio work again than rebooting? I've tried obvious steps like running the troubleshooter and disabling and then re-enabling the devices.

    USB Audio Device Preventing Sleep (Windows 10)

    Background

    I have been having issues with my computer not entering sleep and also waking from sleep since Window 8.1. I had hoped that Windows 10 would resolve these issues, but unfortunately this is not the case. I had noticed that the problem would occur whenever my headset (Hyper X Cloud II) was plugged in, but it was not exclusively occurring when plugged in.

    I recently got extremely fed up with my computer waking from sleep very consistently and decided once again to try and solve the problem.

    Attempted Fixes

    To start off, in Power Management:

    • Disabled wake timers
    • Enabled USB selective suspend
    • Set the computer sleep time to 1 minute of inactivity to see if any changes had an effect

    To identify the cause of what's keeping the computer from waking I used powercfg in an elevated command prompt:

    Which returns the following:

    What I had noticed with my headset was confirmed by the USB Audio Device entry under system. If I unplugged my headset, both the USB Audio Device and the Legacy Kernel Caller entries were gone upon running powercfg -requests again.

    The problem still persisted after unplugging the headset. So I then ran the following command to prevent the Realtek High Definition Audio driver from preventing sleep.

    This did in fact allow my computer to enter sleep. Upon plugging in my headset again, the problem came back. So naturally I executed REQUESTSOVERRIDE again for the related headset drivers:

    Unfortunately this did not fix the problem. To ensure that my REQUESTSOVERRIDE command took effect I ran:

    Which did show that my override requests were in effect:

    After this I tried:

    • Using Device Manager and ensuring every USB port was permitted to turn off devices in order to enter sleep
    • Uninstalling the Hyper X Cloud II device and reinstalling
    • Confirming the powercfg -requests entries with powercfg -energy report
    • Control Panel -> Sound -> Headset Earphone-> Advanced and unticked "Allow applications to take exclusive control of this device"

    TL;DR

    How can I prevent my USB Audio Device (in this case Hyper X Cloud II Headset) from preventing my computer to enter sleep?

    I have used powercfg -REQUESTSOVERRIDE to remove all entries that come up in powercfg -requests and ensured in Device Manager that all USB ports are able to turn off devices to allow the computer to sleep.
