No Audio On Boot Camp with iMac Pro, Latest Software

i got a seem problem as yours,

and you are lucky i can advice do not nuclear your mac, it's not work at all.

today i have trying at least 3 time completely wipe the macos and reinstall windows via bootcamp.(i tried mac os 10.13 and 10.14beta).

it's still has one god **** speakers device unknown.both i tried win10 at version 1803 and 1709 without update.so it's not the problem of windows update.

and i also tried reinstall device driver manually, which zip from bootcamp 6.1, it's not working at all.

compare the very early time, the audio device work very well via windows 1709 which i'm not still install bootcamp.

i assume it's the problem of hardware or the version of bootcamp.though it's passed the hardware test.

i still struggle this freak night to try to fix it.**** it.

if you got something ,thanks to share.

I have seen that there is an issue regarding Mojave. I have the same problem and the consensus is that Mojave beta upgrades the firmware of your iMac Pro and the boot camp audio driver is not compatible.

I think we will need to cross our fingers that apple are aware of the issue and release an updated boot camp driver when Mojave is officially released.

Apple released an updated driver in Windows update. I've installed it and now the audio device DISPLAYS as functioning. Except still no audio comes out and it doesn't detect when I insert headphones.

yeah on windows update have update, but is strange... apple all time put updates in apple software update... nvm sound not work ))) but icon DISPLAY as functioning 😀 waiting mojave

if you install mojave and it fixed sound alarm here plz )

installed "Apple System" and my icon sound red, in device manager - can't start device, trying reinstall windows now mb it fixed problem

can you show what version apple device sound driver you installed ? ( 2018 year ? )

Problem seems to be the "Apple media 8/7/2018 6.1.7000.0" sound driver update for the iMac Pro which was installed during a normal Windows software update recently.

Solution, at least for me: open the Apple audio device in the windows device manager, check the properties, and from there in the drivers section, simply uninstall the device including the driver. Then, still in the device manager, search for plug and play devices. This automatically installs the older 6.1.6900.0 driver from 6-dec-17 which works perfectly.

The above solutions don't work for me. I had the sound working, but did an update round (first to Mojave, then updated Windows to the most recent build as of now) which left me with crappy video and no audio under Windows. I then installed the most recent (tested) AMD driver from bootcampdrivers and that worked fine. But after tinkering around a LOT I still don't have sound through the internal speakers or through headphones that are plugged in to the jack. Bluetooth audio (UE Boom) does work.

I've tried different versions of the audio driver (the old backupped one, the most recent one from Bootcamp), none worked. Current one is the 10.0.17143.1 one from 11-04-2018. I do have the AMD High Definition Audio as a device available (actually, 6 times) but those all say "Not Connected" even though the driver is up-to-date. I can't find a way to activate / use that one.

So yeah, I'm at a loss. Using the crappy bluetooth speaker workaround now, but that is far from ideal. Any ideas anyone?

It's an iMac Pro 10 Core with a Radeon Pro 64 running Windows 10 on Bootcamp. I'm sceptical of Mojave being the problem, as this is a problem under Windows 10 (when booting to MacOS everything is fine).

I see, that could interfere with things. Any ideas what I can do to fix it (other than using a bluetooth speaker)? I'm at a loss currently. I'd hate to have to do it, but if it IS an EFI update, would a clean Windows installation (ugh) do the trick? Under MacOS the Bootcamp app can't seem to access my Windows partition anymore...

It may. Macs with Apple T2 are problematic.

Do you have any third-party NTFS software? Do not install any, if you do not have any.

Can you try to re-install W10 1709 instead of W10 1803? If the speakers worked in the previous version, and they work correctly in macOS, then the hardware seems to fully functional.

See this Windows 10 1607 ISO Download page .

first, im not see on apple software update any update for sound

second I think we need wait official release Mac OS mojave, install it, then update windows audio driver 😉

waiting to 🙂

Try on Windows Update. I received 2 updated Apple drivers - one of which had something to do with MEDIA.

I agree on the other point, let's hope this is fixed on Monday
