Mute/unmute, Change master volume in Windows 7 x64 with C#

How can I adjust master volume in Windows 7 with C#?

I have seen an excellent implementation using winmm.dll here, but it works with XP and not with Windows 7.

+2  A: 

CodeProject has a very good sample here. Note that it relies on COM interop completely (check COM interface like IAudioEndpointVolume and IAudioMeterInformation on MSDN if you are interested in implementation details), and works ONLY for Vista/Win7 and higher.

Minimum supported client: Windows Vista

Minimum supported server: Windows Server 2008
