Is it possible to tell a specific app to lower volume, using intents? I would like to be able to use Tasker to tell the HEOS app to lower the volume.
EDIT: Heos is a streaming system, controlled through an app. When the music is playing, and my phone is on the same wifi, I can control the volume of the system by opening the app and pressing the volume rockers. But it is rather cumbersome to open the app each time, so I was hoping to create a custom widget to do this instead.
