After installing Windows 10 with Boot Camp Assistant for my Late-2016 15" MacBook Pro, I'm finding maximum volume to be almost inaudibly quiet under nearly all uses. The audio is deafeningly loud at full volume under macOS, so something is definitely wrong

Windows shows the volume is maxed. Nothing obvious in control panel. The driver is apparently "Cirrius", but I know nothing about it.

Searching around yields a lot of similar complaints from 2009, and advice to install Realtek drivers, but that's so out of date I don't suspect I should risk it. Any ideas?

  • I have the same problem. On macos volume is fantastic but on windows 10 very low. Have you solved this already? – Yusuf Demirag Dec 28 '16 at 19:55

I have the same problem on a MacBook Air with the Cirrius drivers. I managed to get the volume to boost a little by checking the "disable all enhancements" box on the sound properties (as some online had suggested from a few years back), but still no where near as load as it gets on a Mac. It is certainly a driver issue but so far I've yet to find a fixed driver.

    That actually worked. I don't know who downvoted this. +1 for valid answer. – blez Jan 17 '17 at 20:48
  • I found that enabling Loudness Equalisation actually fixed the problem for me, of course this answer is quite old and Windows 10 is a moving target, I'd suggest trying them all out and seeing if that helps. – Dean Smith Aug 16 '20 at 9:25

I had this issue... Solved by booting into MacOS and turning volume all the way up... then plug in headphones and turn volume all the way up... It was set to like %10 volume.

The windows driver doesn't access the chip's volume properly.

  • This worked for me. It seems 100% for Windows is whatever level macOS is currently set to. – somnolentsurfer Jul 3 '20 at 2:38

I did everything listed above and none worked.

This one did the trick.

In windows 10:

  1. Right click the volume icon in the task tray, and choose Open Volume Mixer.
  2. Click device speakers
  3. Spatial Sound
  4. Windows Sonic for headphones.

I dont know why but now my imac with windows 10 has max volume.


I experienced this problem the last few days in Windows 10 (using Bootcamp) on my 15" MacBook Pro when playing videos through the built in speakers. To fix it, this worked for me:

  1. Right click the volume icon in the task tray, and choose Open Sound Settings.
  2. Scroll down to Related Settings and click on Sound control panel.
  3. Scroll down and select Speakers, and then click Configure.
  4. Change Quadraphonic to Stereo and back to Quadraphonic again.
    (I actually Tested the sound for Stereo before changing it back again, but not sure if that's required).
  5. Hit Test and the sound should come blaring out!
  6. Hit Next, then Next again, and then Finish to end the wizard leaving the defaults in place.
  7. Click Ok in the Sound control panel window.

You're hopefully working now!


Just go to Device manager (Right click on This PC > Manage, Expand sound, video and game controllers, Find Cirrus Logic drive, go to Properties, Disable this driver, then restart PC, and after that go to the device manager again and Enable this driver. It helped for me and now volume is back to normal.


I had the same problem in my MacBook Pro (Mid 2010) running Windows 10 64bit.

The sound worked installing the CirrusDriver4206x64 on the folder Drivers/Apple/ of Boot Camp downloaded with Brigadier.

But the sound was low in comparision with MacOS. So, I did the steps above, and in the last tab named "Spatial Sound" I disabled it.

Now the sound seens like in the MacOS.

I also had this issue until I looked into the Speakers Properties > Advanced tab and saw that it was set to a 24 bit quality, changed it to my macOS default (32 bit 44100Hz) and it ran just like on macOS


I installed win 10 on a dell optiplex, low sound on headphones, tried all the adjustments, (another dell was OK though, it can be individual PCs), anyway I solved it by using a usb sound card from ebay £ 3 -4, it has mike and headphone jacks, and sound is back to normal...it might also work if you got usb headphones but not tried yet...


Here's what I did~

Playback Devices -> Cirrus Logic CS4208 -> Properties

Tab: Levels - Make sure they are at 100.

Tab: Enhancements - Turn on Loudness Equalization then open settings for that option and set the release to long.

This made Netflix max volume substantially louder.


I solved it.

  1. Right click the volume icon in the task tray, and choose Open Sound Settings.
  2. Under Cirrus click on "device properties"
  3. Click on Enhancements
  4. Check on low frequency, Speaker fill, loudness equalization



This has nothing to do with the Driver. You simply go back into MacOS and you will find that your volume was low or not set to full. This limits the volume in windows to whatever the volume was in MacOS.

Fix. Go back into MacOS. Set Volume to 100. Restart and go into windows. 100 volume in windows is now the same as 100 volume in MacOS.


SOLVED. Set Loudness Equalization to Short. Here's how -

Go to speaker settings. Select 'Enhancements' tab.

Check 'Bass Boost' AND 'Loudness Equalization'.

The most important part, with Loudness Equalization selected, click on the Settings button just below it. Then change release time to 'Short'. BAM! That last step makes it as loud as the Mac. At laaaaaaaaaaaaast!

Image below shows it as well.

  • How is this answer any different then this previous one? Your answer is exactly the same. By doing this you risk downvotes. – fsb Sep 12 '19 at 19:06
