I installed Windows 10 (April 18 update) on external SSD drive that can be selected on the iMac's startup. Run the Boot Camp Windows Support Software and everything is fine, Apple mouse & keyboard, except audio is missing. Windows 10 Device Manager app does not show any problems with the drivers such as yellow triangles or red crosses. In fact, when a video is played the green volumen bars in the audio device driver properties move but there is no sound at all.
- iMac is the latest 2019 model.
- Windows 10 is up to date according to Windows update app (had to use April 18 update as start version since the installation does not work with October 18 version).
- Drivers are update to date according to Windows.
- Installed Windows 10 on external SDD following these instructions: https://blog.macsales.com/40947-tech-tip-how-to-use-boot-camp-on-an-external-drive, https://medium.com/@svenkirsime/install-windows-on-the-external-ssd-hdd-for-your-mac-5d29eefe5d1, .
