  1. Enabling Discrete Device Assignment on Windows 10


    Hello,


    I've been experimenting with different versions of Windows 10, and I am almost ready to buy a license, but unfortunately there is one major problem that is a showstopper for me. For my work, I need to be able to pass through physical devices to a linux-based HyperV virtual machine. Microsoft calls this feature DDA or Discrete Device Assignment, and as far as I can tell it is only supported on Server editions of Windows. Unfortunately it is not viable for me to use Server as my main workstation OS. Dual-booting with it is also not an option.


    Is there any way to somehow enable this feature on Windows 10 with some sort of registry/group policy hack? Or perhaps is it possible to move the feature from a Server installation over to a Win10 installation so I can use it?


    My main goal is to pass through a PCI device a USB3.1 controller/root hub to a linux-based virtual machine. GPU passthrough would certainly be useful in the future, but right now it's not as important as the root hub.


    DDA seems like a mature technology at this point, so I think it should be included in Pro, or at least in Enterprise/Pro for Workstation. Linux can already to this out of the box and it's a free operating system.


    Currently this is the only thing that's holding me back from getting a proper license for Windows 10, and I would really appreciate it if someone form the Server or HyperV teams could point me in the right direction and show me how I can enable the feature.


    Thanks in advance

    :)

  2. Re-enable audio device

    Hi,

    I would be happy to assist you.

    Before we proceed with troubleshooting, I would need little information on the issue.

    • Are using speakers / head phones to listen to audio?
    If you have disabled the audio device, then you might not see it under the list of playback devices. I would suggest you to follow these steps to make sure you see the disabled devices:


      • Open
        Control panel
        .

      • Click Hardware and Sound and then Click on
        Sounds.

      • Under Playback tab, right click on the empty area and make sure
        “Show Disabled Devices” has a check mark on it. If headphones/Speakers are disabled, it will now show up in the list.

      • Right click on the device and
        Enable it. Click OK.
    If the issue still persists, try enabling speakers automatically using steps below.


    • Go to Settings> Click on themes> Advance sound settings> right click on the speakers or the audio device youo have connected > click on
      Configure device.

    • Test the sound level you want, click Next.

    • And configure the audio devices.

    Hope this helps you. Do reply if you need further assistance on Windows 10.

    Thank you.

    Enabling Discrete Device Assignment on Windows 10

    Windows 10 Tweaks

    Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

    Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

    • Open a new Explorer window.
    • Click View in the ribbon.
    • Click Options.
    • Under General, next to “Open File Explorer to:” choose “This PC.”
    • Click OK
