Get Master Sound Volume in c#

Question

I need to get the current volume of the output to the sound card.

Any ideas how?

Answer 1

I solved this when I was working on a (still yet to be released...) application that initiates some kind of "elevator music" when no other sound is present.

Followed the brilliant tips given by Mark Heath, I got what I wanted :

 using NAudio.CoreAudioApi; 
 MMDeviceEnumerator devEnum = new MMDeviceEnumerator();
 MMDevice defaultDevice = devEnum.GetDefaultAudioEndpoint(DataFlow.Render, Role.Multimedia);
 string currVolume = "MasterPeakVolume : " + defaultDevice.AudioMeterInformation.MasterPeakValue.ToString();
