How to check if any sound is playing

[AlexZ]

Thanks for your help.

I was looking for more info and it seems that IAudioMeterInformation does the trick:

CoreAudioApi on GitHub
Programatically setting the default playback device
Our dear neighbors...
Our other neighbors...
Programmatically (or Command Line) change the default sound playback device in Windows 7
IAudioMeterInformation = {c02216f6-8c67-4b5b-9d00-d008e73e0064}

Interface Functions

Please, Gintaras, is there any chance to implement this? Unfortunately, I am not skilled enough to do it by myself.

Thanks for your support. Best regards.
