Remarks

 

Sets the muting state of the audio stream that enters or leaves the given WASAPI device for the current process. The current muting state can be obtained through the WASAPI.DeviceMuteGet method.

 

If you need to modify the master mute for the given WASAPI device, shared by all running processes, use the CoreAudioDevices.MuteSet method.

 

This method is only intended for usage with Windows Vista and later versions.
