That's true. Actually, how could you assume that they might fit? VDMSound is based upon the API the NTVDM does supply - and this API is supplied by NTVDM exclusively.

To emulate a (non-trivial) hardware device it's not sufficient to be able to "trap ports". One will also have to "virtualize" IRQs, and, for memory-mapped devices, memory ranges. It's pretty complicated to emulate the VGA in 16-color modes, for example.

The next version of HDPMI will at least support the port-trapping and hopefully also the IRQ-virtualization, both for clients running in ring 3. So, if you're a bit skilled, you may adapt VDMSound to HDPMI. Good luck!

Well, possible is a lot, it's software - but it's rather unlikely to come into existance.
