Windows API - Soundcard playing & stop audio event RRS feed

  • Question

  • Hi There!

    What I' trying to found is some API call that detects when any audio is playing at the soundcard. Is not a recorder, I'm not looking for an audio playing application. My issue is detects from my own application when any other software or windows send audio to speaker.

    So, I guess that may be is an API some there that let me detects when sound is being played and ends.

    The device input is not a record input (microphone or line-in) it's the speaker output itself.

    Is not a Vu-Meter but can be part of them. It's an API call that trigger an Event that give me a true/false when audio starts or ends. 

    Best Regards!!

    I think PlaySound with SND_NOSTOP will help.  I've never done this, so it is kind of a guess.
