1. Are there any actions that can increase/decrease the current volume (of both sound and music)?
Currently, I see only "Set volume" for both, which requires you to set a specific number.
2. Apparently, the action "Set music volume" doesn't have any effect at all. The sound files (played using Play music) still plays at the same volume regardless of what I do. No such problem for Autoplay sound though. Is there something I'm doing wrongly?
