Why? After all, if the video card has HDMI audio, then the OS will be two
entities:
one - the video card,
other - audio device with capability HDMI.
So I disagree with you.
The more so that the device OS divided into separate classes. Here is
information
on these classes of devices and need to displayed. I.e. divide the devices by
classes,
but not types, like:
enum ClassOfDevice { .... }
For example,
on Windows:

on Linux, like:
http://www.mjmwired.net/kernel/Documentation/driver-model/class.txt
on MacOSX, like: similary
