change volume win32 c++

Question

How would I go about changing the sound volume in c++ win32? Also how would I mute/unmute it? Thanks for the help!

Answer 1

If all you want to do is change the volume then you can use the virtual key codes to change volume like this:

void changeVolume()
{
  INPUT ip={0};
  ip.type = INPUT_KEYBOARD;
  ip.ki.wVk = VK_VOLUME_UP;   //or VOLUME_DOWN or MUTE
  SendInput(1, &ip, sizeof(INPUT));
  ip.ki.dwFlags = KEYEVENTF_KEYUP;
  SendInput(1, &ip, sizeof(INPUT));
}
