How to play Phantom of the legend of zelda on the computer without a microphone in the hourglass?

If you want to use a microphone in the game, you don't need a microphone at all. Double-click the volume in the lower right corner of the screen to open the dialog box. Execute Options → Properties → Check Recording → Check Stereo Mix or Stereo Mix in the Recording Sub-selection box → Turn on a piece of music after confirmation, and then turn the volume of the stereo mix to the maximum, and it will help you blow it.

Come closer when you blow out the candles.
