i've been trying to detect when the master volume is set to mute.  i'm using the winmm.dll library to obtain the actual volume and  the max volume but i can't obtain the instruction that indicate the master volume is set to mute.  i don't know how to detect  what instruction is thrown when the mute is enabled.  

the major problem i have is that although i can obtain de currentVolume or the actualVolume, when i set the master sound to mute, i don't know what instruction of the winmm.dll library i need to invoke to obtain that the mute is enabled.

i have a getVolume function which return the currentVolume but although i set master volume to mute, the function return the currentVolume before i switch to the mute status; the currentVolume doesn't change it value and i have no idea to obtain the mute status.

I think this link should be more useful. It has c# and VB examples of muting and unmuting the sound card, as welll as other winmm.dll functions.
