No audio in Windows 10 BootCamp

[blasto2236]

Just installed BootCamp, which I've done a number of times without issue. The problem this time is that the BootCamp drivers installer kind of hung during the first launch of Windows 10. It finished, but after restarting manually a bit later, it never actually installed the drivers, I don't have the little BootCamp icon in the taskbar, and most crucially, I have no audio.

It recognizes the internal speakers and externals connected through the jack, and acts as though it is playing audio with no issues, so I'm sure this is related to the driver installation.

Which brings me to my next problem: In the latest version of Bootcamp on newer Macs, it does not offer an option to manually download the drivers. In fact, it circumvents the drivers-on-a-USB process altogether, and creates a 3rd little partition that contains them. However, that partition is gone, and so far as I can tell I have no way to access the drivers at this point.

I've already downloaded a 60GB game before realizing this was going on, and would love to avoid starting all over if at all possible. Has anyone run in to this? Is there anywhere I can find a manual download of the drivers for a 27" iMac Retina 2015?

Yep! Boot Camp assistant no longer offers a download of the drivers if your Mac doesn't require a USB drive for the original install.

When I open BCA, the only option I'm presented with is removing the partition.

Additionally: I removed the partition and started over. Same result. I appear to be stuck until I can find a fix or a way to manually download the drivers.

Edit: I found a workaround in BCA. Rather than choosing "Continue" when the assistant starts up, I selected the "Action" menu in the upper left and chose "Download Windows Support Software", and it is doing a manual install on to my flash drive. Hopefully this works after it finishes and I run it in Windows. Will update here after.

Edit 2: That worked like a charm. For whatever reason, the new method Boot Camp uses to automatically install the drivers without a USB has some kinks to work out, I guess. Installing them manually after the fact resolved the issue.

On the Mac side. I was unable to access BCA in Windows due to the driver issue.

thank you replying to this thread even though it been so long. im currently downloading the drivers from BCA on the mac side. hopefully this works for me. one other thing i read online was that the windows 10 had to show as Bios instead of EFI (under BIOS Mode) in the system summary when you pull up system information on the windows side and thats why the audio driver wont install.

ive tried running the install on a bootable usb that has been partition as a MBR (Bios or EFI) but it will freeze up the macbook as soon as i click on the drive. ive never ran into this issue before any help or advise would be great appreciated!
