If your Camera is not working in a virtual machine in Hyper-V or VirtualBox, and you see a black screen or an error stating ...
If headphones are not working with the virtual machine, follow these instructions, i.e., enable enhanced session mode, install guest additions, etc.
If you need to use virtual machines on Linux, try Virt-Manager. Virt-Manager is more reliable than VirtualBox. Virt-Manager is completely free and open-source. I'm a long-time supporter of VirtualBox.
Just one issue stands between me and my Linux daily driver, and this solution is all it'll take to turn the tables.
