Master Volume Control in C#

I'm looking for a nice compact class for controlling the Master Volume of the
PC speakers in C# *without* using DirectShow. I have found one sample that
works fine for getting and setting the volume. But it does not support
getting and setting the MUTE state. This means that if the computer is MUTEd,
no matter what I change the volume level to, it doesn't make any difference.
It is still MUTEd. So I need to be able to control the MUTE state as well.

Any samples, please?

Hi Alex,

Below example is using APIs from winmm.dll directly to control the volume
and can mute the sound:

#Audio Library Part I - (Windows Mixer control) - The Code Project -
Multimedia

0&fr=26&select=1366906

Please let me know if this is what you wanted. Thanks.

Hi Alex,

Have you tried above example? I think it should be working for your

Anyway, please feel free to let me know if there's anything else I can help.
