Then if you uninstall the driver on the Device Manager by using the “Uninstall device” option, you will actually be able to remove the driver from your system, but the copy stored on the Driver Store won’t be deleted by that, so Windows Update will re-install it again on start-up using that copy. If you try to uninstall the driver using the Conexant uninstaller, it just disables the driver but it doesn’t uninstall it. And no guide mentions this.īy default, Windows prefers the Conexant driver over the default one from Microsoft, making Windows Update to download and install it automatically. There, Windows has a local catalog of all the drivers that have been installed on your machine as well as a copy of them, and one of its uses is to provide the user with the ability to swap between certain drivers without having to reinstall them (the list of drivers that appears when you use the “Choose from a list of drivers available on your PC” option on the Device Manager is a mirror of the Driver Store). Back then, I had no audio issues at all.Windows has sort of a local driver archive on each PC named “Driver Store”. I had a Windows 10 installation on this Mac working just find a few months ago, and then I removed the installation with Boot Camp Assistant in macOS once I had no need for Windows. This version of the driver has the same issue for the headphone jack only.Ĭould anyone please suggest to me any other avenues I can try? The name of the driver that Windows selected is the same, however the version number is 6.6001.4.2. I have also installed the updated version of this driver from Cirrus Logic's website to see whether this may fix the issue. The audio driver that came with my Boot Camp Support download which appears to be supported for my model of iMac is "Cirrus Logic CS8409 (AB 16)", version 6.6001.3.38. Neither replacing the audio driver with the Windows default "High Definition Audio Device" driver, nor selecting the manufacturers driver from the Boot Camp Support download from within Boot Camp Assistant on macOS for my 2017 iMac seems to work. I have attempted to reinstall the audio driver numerous time to remedy this issue. Audio sounds just fine through the iMac's normal speakers. The sound issue isn't apparent when the headphones are unplugged. The volume controls don't change the loudness of the tone. It's as though any sound that is meant to come from the audio output is a consistent high-pitch tone. For me, it instead emits a high-pitch tone for a few seconds, and then it ceases. For example, if I have my speakers plugged into my iMac via a 3.5mm audio jack, and change the volume of the headphones output from the taskbar, Windows should emit a pleasant chord sound to test the audio volume. Whenever I attempt to use audio through my headphones port, I hear a shrill high-pitch tone. The installation of Windows performed successfully, and the Boot Camp drivers were installed correctly too - apart from the sound driver it seems. I have macOS Big Sur 11.5 installed at the time of the Boot Camp installation of Windows. I have recently reinstalled Windows 10 Home on my 2017 iMac 27". High pitch tone when plugged into 3.5mm headphone jack - Windows 10 - iMac 2017 Hey team. I'm not clear on the rest of your issues. There seem to be different instructions to remove the drivers if you are using older versions.įrom the front page of their site, the latest versions seems to state support for apple silicon If you really don't want to restart your Mac right now, you can restart CoreAudio service sudo launchctl kickstart -k system/ The driver would still be loaded in the System until next restart. This command will Remove the eqMac Audio Driver: sudo rm -rf /Library/Audio/Plug-Ins/HAL/eqMac.driver/ The driver does not have any effect on the System when eqMac is not running, however, if you'd like to remove the driver as well, please follow the instructions below: This will uninstall the app itself, but there still will be a driver installed. You can just move eqMac.app into trash, like any other Application. In the EQmac FAQ they say you can just drag the application into the trash (or option-click move to bin) and that will get rid of it.
