Sound not working in windows 10, but working on Mac Sierra

[damnit]

I just installed Windows 10 on my Macbook Unibody late 2010 and everything is working smoothly, but the sound. I tried installing the latest realted driver but still nothing. When I play something the bars in the volume mixer are moving. There's no sound even with headphones. There's also a red light coming from my jack. What might be the problem?

No idea what might be causing your Windows problem, but the red light coming from the headphone jack is from the optical digital output. You can plug a miniTOSLink cable into your headphone socket and plug the other end into a DAC (Digital Analog Convertor)

The thing is the sound works perfectly in Mac OS

Then, the problem is likely either driver related or you need to update Boot Camp. Try updating Boot Camp from the Windows 10 Control Panel Boot Camp item. You state above that you tried installing the latest driver, but if it isn't one of the drivers included with Boot Camp, it likely won't work. If all else fails, try reinstalling the Boot Camp drivers.

Also, your MacBook can not be a late 2010 model as there is no such model. The last MacBook before the new retina 2015 model was the Mid 2010 model.

It would be worth having a look through the sound settings to see if anything is muted.

I know nothing about running Windows on a Mac so I don't know if you see things like Device Manager and Control Panel as you would on a PC.

Just as a matter of interest, do you have the necessary cable and hardware to be able to check and see if the digital output is supplying sound?

A thought: If the red light is on, it's a fair bet that the RealTek drivers have picked up on the existence of a digital output. In fact, changing the driver's output might do the trick. You are getting processing, as indicated by the lights in the mixer. Looks like the issue is between mixer and speakers.

The output is probably set to S/PDIF. It needs to be set to whatever the analog option might be. You'll probably need to reboot once you find it and select it.

Thanks for letting us know.

Good to hear it's working properly.

Actually, he's fortunate to get it working at all since according to Apple Windows 10 is not supported on his machine. I should have looked it up when he first posted the sound problem.

have another problem. I was on my Mac using bootcamp and suddenly the screen went white. It is turned on as I can hear the sound when I plug something in the usb port, i heard the sound skype makes and it charges my phone. I tried rebooting but the same problem. No apple logo, no nothing. White screen all the way. What could be the cause of this?

It's not that

I tried the Cirrus Logic fix to no avail. After days of effort pursuing this problem, here is my solution.

Windows 10 must be installed in the legacy BIOS mode for all functions to work on a Macbook Pro Late 2011. Officially Apple does NOT support Windows 10 on this Mac.

If I started out with a blank HDD/SSD and installed Windows first in the legacy BIOS mode, when it came time to install High Sierra, the installation would complain "Couldn't modify partition map". It appeared when Windows was installed in the legacy BIOS mode, it formatted the disk to MBR, but macOS was expecting GPT.

If I wiped the disk clean and installed High Sierra first, then the Windows installer would complain "Windows cannot be installed to this disk. The selected disk is of the GPT partition style."

This suggests we cannot have a dual boot system of Windows 10 and High Sierra on this particular Mac!

After trying many alternatives, eventually I got it to work!!! Instead of installing High Sierra first, I got it to work by installing Lion first. Not just installing Lion over a disk partitioned by High Sierra, but have Lion format the disk too.

Although Lion prepared a GPT disk just like High Sierra, it is obviously that the two GPT disks are NOT exactly the same! A GPT disk formatted by Lion is compatible with a Windows' MBR partition! My anecdotal observation is that with Lion as a circa 2011 OS, it is more compatible with the legacy BIOS mode. High Sierra being a newer OS is not as backward compatible as Lion.

After the dual boot system was setup, I upgraded Lion to High Sierra without causing any problems for Windows since the update didn't reformat the disk and thus still the same system partition prepared by Lion.

It goes without saying that one must install the Boot Camp drivers for many functions to work under Windows on this machine. The version of Boot Camp I am using is 5.1.5621. If you are on Windows 7, the driver version is 4.0.4033. By the way, Bluetooth audio streaming never worked under Windows 7 on this machine no matter what I tried. Windows 10 doesn't have this problem. The built-in audio jack works under both Windows. Since Microsoft would terminate the support for Windows 7 in early 2020, if one is building a system now, he should avoid Windows 7, not to mention Bluetooth is broken.

Lastly, I didn't bother to run the Boot Camp app under macOS to facilitate the installation of Windows. I found the app quite cumbersome, not to mention it wouldn't offer Windows 10 anyway on this machine. *AFTER* I already setup Windows, I downloaded Boot Camp drivers online and installed them simply as drivers.

P.S. I forgot to mention that how you format each partition initially matters too. When I first setup macOS, if I partition all of them to use HFS+ (since NTFS isn’t available) thinking I can change the Windows partition to NTFS later when the time comes for Windows installation, it will NOT work! My theory is when all of them are HFS+, the macOS installer assumes there will be no other OS on this Mac and therefore no need to setup a hybrid boot partition that can accommodate Windows later!

Welcome to our forums.

Sounds like lots of work. But it appears you were successful installing Windows 10 on a machine that Apple says that it can't be done. I suspect that GPT by High Sierra is geared toward both HFS and APFS whereas Lion can only do HFS GPT.
