Hi Everyone,
I seem to be having one problem after the other installing Windows 10 on my iMac.
After several stressful hours I finally got windows installed on my iMac, however I have no sound what so ever. No sound from the speakers, or through headphones.
I have a little red 'X' next to the speaker icon in the bottom right corner of the screen.
I would appreciate any help with this!
Thanks so much.

iMac (27-inch Mid 2011), OS X El Capitan (10.11)
have you tried to manually install the bootcamp audio driver for your sound chip ?
Hi rudegar thanks for the reply.
I have tried this but not sure if I did it properly. Could you give me some instructions please?
Thanks
Andy
1. If you installed W10 on a 2011 Mac using EFI Boot, your sound may never work.
2. If you installed W10 using a physical DVD and used the standard BC Method, and your Sound does not work, install BC drivers using a USB Flash drive and BC Assistant (the screen shot is from El Capitan, but older versions have similar capabilities). You will need to run setup.exe from the Bootcamp folder on the USB.
3. Since your Mac officially does not support W10, you may also need to try BC5 drivers, which are available at Install Windows 7 and earlier on your Mac using Boot Camp - Apple Support .
Hey there, I seem to be having the same issue. So far I haven't been able to get audio, or a second display via a vga to mini displayport adapter to work. The first time I installed Windows 10 on my Mid 2012 Macbook Pro, I used BCA and a USB3 drive. Had an issue with GPT vs MBR, but with some research, was able to get Windows installed. However, after running the bootcamp setup.exe, audio and a second display haven't worked. I tried erasing the bootcamp partition with DU and burning a Windows 10 iso to DVD. However after reinstalling and running the bootcamp setup.exe, audio still didn't work. Any ideas?
Was Windows installed using EFI Boot on the 2012 MBP? If yes, EFI boot does not expose devices that way MBR installation does (using CSM-BIOS). Are Cirrus drivers installed?
I believe so. And I just tried reinstalling Cirrus drivers with the bootcamp drivers folder, still shows No Audio Output Device is installed
1. Can you check for hidden devices in Device Manager?
2. The sound devices should look like the following, if working properly. (Ignore the highlighted part).
The only thing I see is the High Definition Audio Controller ("The device cannot start") in System Devices:
In Device Manager if you click on View, can you click on Hidden devices and check if there are any audio devices?
Oh, yeah, I guess that would help:
Can you explain the issue with GPT vs MBR? Was the Hybrid MBR deleted to allow an EFI Installation? Macs do not support WiDi, yet W10 installer has chosen them, because it thinks that this is a generic PC supporting WiDi.
Oh I couldn't install in the BOOTCAMP partition because there was an MBR partition table, I believe the error message said. I was able to delete it and create a new partition, then installed.
Was EFI boot manually chosen during the installation?
I don't remember seeing an EFI boot option? What do you mean by that? Sorry
On the 2012 MBPs, the standard method for Windows is an MBR. The BCA installer will create an MBR, and boot from the legacy Windows installer and install Windows. In case a user manually boots from the USB installer, they can choose the Windows or EFI Boot icon. Specifically on 2012 MBPs, which are preUEFI, EFI boot will not work properly. The Audio devices do not show up unless CSM-BIOS is invoked.
Is it possible to re-install Windows 10 without deleting the MBR this time?
No Sound On Windows 10 Help?!
