Q: Audio not working, Windows 10

Good day,

 

I did a clean install (nothing at all on the computer for Windows previously) with a Windows 10 ISO. I have everything working great, but cannot get the Audio to work. It shows a Red X on the speaker icon in the bottom right and I have tried to update/install the RealTek drivers off of the Boot Camp I had and 5.1. Has anyone been able to fix that Red X issue and have audio working? In Device Manager it also has an exclamation on the Audio Controller.

 

Mid-2011 iMac, using Bootcamp 5.1 drivers.

    Was W10 installed using EFI Boot? You can check by running msinfo32 and looking at BIOS mode.

    Yes, it is EFI. I saw other posts that mention EFI doesn't work, so my question would be: how do I change to another way of booting? It was already a pain to get W10 to install in the first place, and not sure what I would do different.

    Instead of EFI boot, do you get an error when you choose the legacy Windows icon?

    I don't have a legacy option. When I hold down the option key, I have OS X, Recovery, and Windows 10.

    Was BC Assistant used to install W10? BCA on your specific model will create a Hybrid MBR which then results in a BIOS/MBR installation. If W10 is installed using a previous W7/W8+ installation, it should also result in a legacy installation.

    It was a clean install, no prior Win7/8+ installation. I did use BCA to install W10. When I looked at the System Information in W10, it showed EFI.

    How much work is it to remove this installation, create a new partition, check the MBR and use a physical DVD to install W10?

    This is just a side project, to see if I can make it happen. So I can do that, though I don't have a physical DVD. Used an ISO on a USB to install (modified plist to make the computer able to use USB)...

     

    Do I just delete the partition and then create another one? What type of partition? I have not 'checked' an MBR before, but I can find out how online. Finally, can I put the ISO on a DVD and use it to install?

    Use BCA to remove Windows (do not use Disk Utility). Burn the ISO to a physical DVD. You can leave the current USB installer as is. Use BCA's last option Install (or Remove) as necessary and test.

    Just got some DVD-Rs (live in Greece right now, not as quick to get things here) so I'll work on it soon. I saw an answer concerning audio card Driver...could it be something simple like that ?

    If it was a driver issue, BC driver installation should have installed. The issue is that the BC drivers do not see the audio devices when installing with EFI boot.

    So tried to use BCA to remove Windows 10, and got this error: Your disk could not be restored to a single partition.

     

    Any advice for proceeding?
