Audio Mixer Control in VB.NET

[Andrea V.F.]

I need to control (Get and Set) this parameters of Windows Audio Mixer:

- Master Volume Mute
- Master Volume Level

In addition, but not mandatory, I need to control also the PC Speaker
Mute and Volume. PC Speaker control is aviable only in some Systems
such as laptops, in others systems there is no control of PC speaker in
Windows Mixer.

How is possible to do this in VB.Net (Visual Studio 2003)??

Thanks for the Help.

Andrea

Hi there... You can do it by using some API calls so you need to write your
wrapper class (where all API function prototypes reside). This link show you
the functions you need to use (The code is written in VC++ 6). Hope you find
useful this information.
