How to programmatically set the system volume?

How can I change the Windows System Sound Volume using a C# Application?

Solution

  • I'm a bit late to the party but if you are looking now there's a nuget package available (AudioSwitcher.AudioApi.CoreAudio) that simplifies audio interactions. Install it then it’s as simple as:

    CoreAudioDevice defaultPlaybackDevice = new CoreAudioController().DefaultPlaybackDevice;
Debug.WriteLine("Current Volume:" + defaultPlaybackDevice.Volume);
defaultPlaybackDevice.Volume = 80;
