Hello Tim, I have to disagree. Lack of standards compliance from Microsoft is a barrier for vendors and dissuades consumers from purchasing 'unsupported' hardware. Build it and they will come. WASAPI has enabled us to push this project forward. I'm not convinced anyone could have made a business case for its provision. But eventually it arrived, and was quickly supported by all the major DAW's. Surely a much, much tougher nut to crack than a relatively mundane driver .

There are a billion Windows machines in the world. How many really need to use USB Audio 2 devices right now? Maybe 1,000? Maybe 10,000? 999,990,000 out of a billion is 100%, to four significant digits. That's the problem Microsoft faces. They need to make sure all of the corporate secretaries in the world can listen to Michael Bolton through iTunes. 16-channel 192 kHz audio is cool, but there just isn't widespread business demand for it yet. -- Tim Roberts, timr@xxxxxxxxx Providenza & Boekelheide, Inc.
