I thought I'd better post an update to my progress on the vSound virtual sound card driver. I have been looking at the WDF stuff from Microsoft and how it could be supported in the upcoming Vista. There are some considerable issues in writing sound drivers that will work in Vista with the Digital Rights Management (DRM) crap. I am hoping to write the driver so it will work in W2K, XP, and Vista.
I would very much like for the driver to work like jack does in Linux. Some things are not possible in Windows, but I think I can get close to jack's functionality.
I hope to have something together to test in a month or so.
I posted a photo of a almost complete OZY board on the HPSDR Wiki. Testing is going well. See updated info at hpsdr.org
