Next, I manually removed the entry for Other Devices 'Multimedia Audio Controller' and went through the VMWare Tools uninstall/re-install process. The red X in the system try remains, along with the lone entry for Other Devices 'Multimedia Audio Controller'. Reinstalled VMWare tools using the 'Typical' option and rebooted again. Device Manager now shows two entries for Other Devices 'Multimedia Audio Controller' and 'Unknown device'.

After logging in, I noticed the speaker icon in the system tray is still marked with a red X.

References for this type of error harken back to Win XP and Vista days I've tried what I've seen but nothing has worked so far.Īh, were it to be that simple but alas, I removed VMware Tools and rebooted to Guest OS as instructed. I've tried manually installing the driver, but that fails with the message ' The installation failed because a function driver was not specified for this device instance'. I've rerun the VMWare tools update first Repair, then Modify where I removed the device from both Device Manager and VMWare, rebooted, reinstalled, and the condition persists. Device Manager does not show an entry for Sound, Video, and Game Controllers like the 'good' VM does, but rather an entry for Other Devices where the Multimedia Audio Controller is shown with a yellow triangle and the device status is listed as Code 28, 'The drivers for this device are not installed'. When clicked, Windows attempts to repair the error and fails. The speaker icon in the system tray is marked with a red X. One of the VMs rolled up just fine, but the other is throwing errors regarding the audio controller. I have two, 64-bit Windows 10 Pro VMs running on a Windows 10 Pro host.
