Yesterday the internal speakers, headphone jack and microphone stopped working. Reinstalled bootcamp partition and Windows but did not solve issueĪny pointers would be highly appreciated.īootcamp and Windows 10 - speakers and headphone jack stopped working I have a 2019 iMac on which I run Windows 10 via Bootcamp since buying the iMac. Sound in Windows only after first boot from MacOSĪlso installed latest drivers thru Apple Software Update in WindowsĪlso tried reinstalling Windows Support from MacOS bootcamp utility However, when iMac is turned off and restarted directly into Windows, there is no sound.Īfter this issue, tried reinstalling Windows by removing bootcamp partition and reinstalling Windows, but did not solve issue. When booting into Windows from MacOS (start iMac in MacOS then restart and boot into Windows) sound works. Have been using Windows thru Bootcamp without problems until recent update of MacOS to Monterey.Īfter update, there is no sound in Windows though it works perfectly in MacOS. MacOS Monterey Update Causes Bootcamp Soundcard Driver to Fail After upgrading to the latest MacOS Monterey, there is no sound in Windows. Was there something with my reinstallation process of macOS that messed things up? Should I choose a different File System (since HFS seemed to have been causing the BSOD problem)? Or is there anything I can do so that I can go back to a regularly functioning Windows Boot Camp partition? And I am also quite perplexed as to why my Windows Boot Camp was working just fine on the same version of macOS just a week ago and now after this reinstall everything broke. I really hope that there could be a solution to this. Those are the only two instances where I see my sound working.

Additionally, when I shutdown my Windows, and in the few seconds before the screen goes dark, the speaker icon also flashes with the curved lines indicating that my sound is working. However, for some reason, it was only a flash and icon went back to a red circle indicating that there are no drivers. However, I have noticed that when during the multiple times when I installed the Boot Camp drivers, my speaker icon flashed for a fraction of a second with the levels (three curved lines) indicating that my sound drivers were installed. Reinstalling Boot Camp drivers from files downloaded by the BC Assistant in macOS.Now, I am stuck on the second issue, which is that the sound is not working. I followed this thread ( ) where I renamed both AppleHFS.sys and AppleMNT.sys to sys.bak, which solved the BSOD problem. I wanted to do a clean wipe of my MacBook Pro mid 2012 so I reinstalled macOS and upgraded to Mojave then reinstalled Windows.įirst, my laptop was crashing with KERNEL SECURITY CHECK FAILURE.
