B4J Question Check or set system volume (PC)

Are you playing the sound with MediaPlayer? Have you tried to change the volume with MediaPlayer.Volume?

Hi Erel,

Thank you for the response. I can set the volume of media player, but if the master volume is low or muted the mp volume has no effect (no sound is heard). So I would like to warn the user that the count down timer will not be heard as the master volume is turned down. (Or alternatively adjust the master volume when the counter is completed.

The only working option seems to be to use a tool such as NirCmd with jShell: https://stackoverflow.com/a/37400825/971547
