If you have worked with the new Core Audio APIs introduced with Windows Vista and also available in Windows 7 you may have noticed that Microsoft appears to have forgotten to include any means to change the default audio playback or recording device.

Well, the thing is that Microsoft didn't forget and this is "by design" as Microsoft feels that applications should not be able to change user defined settings.

This (bad) decision has left audio-related applications crippled when running under Windows Vista/7... up until now!
MixerProNET 2.1 introduces an extremely easy way to change the default audio device by simply controlling a Boolean property.

By simply setting the Selected property to true on any audio device, MixerProNET will set that particular device (or mixer, as known by MixerProNET's API) as the default device (or audio end point, as known by Core Audio's APIs).

Also available in version 2.1 is the introduction of a .NET User Control that mimics the look, feel and behavior of the TrackBar control used in Windows own mixer application.

As announced a few days ago, I've released the library that it's now part of MixerProNET to let you have full control over all the mixers in any installed sound card under Windows Vista and Windows 7. The library is based on the work by Ray Molenkamp from CodeProject.

Although the library is still missing some of the Core Audio API interfaces, it provides all the necessary resources to let MixerProNET (and you) enumerate all audio end points and manipulate all the exposed controls.

The library's source code is written in C# and is provided as a Visual Studio 2010 project.

MixerProNET 2.0 is a major upgrade which provides full support for querying and manipulating the mixers, lines and controls of all audio devices (sound cards) under Windows Vista and Windows 7!
Support for previous versions of Windows is, of course, also supported.

Here's a detailed list of what's new:

• Support for Core Audio APIs through an abstraction layer which allows MixerProNET to provide full support under Windows Vista and Windows 7 while still maintaining the ease of use of the library
• Intellisense support for all its members
• Many bug fixes for the legacy mixer API support
• Compatible with both 32bit (x86) and 64bit (x86) versions of Windows
• New documentation using the Microsoft Help format

For a more detailed description regarding the support for Core Audio under post-Vista versions of Windows, please refer to MixerProNet's web site.

This new version incorporates a new installer which should minimize the potential problems of adding a new library to the GAC.
Additionally, this version has been updated to accommodate some of the new features in DXVUMeterNET.

We're very proud to announce the availability of the .NET version of MixerPro.

MixerProNET is a powerful .NET based class library that provides access to the lines and controls of installed sound card.
Through the use of classes and collections the MixerProNET engine is the easiest and most powerful method for developing applications that need to read and/or change any parameter from any sound card.
