Volume control (modify)

hi, there is a volume slider:


[color=black][font=Arial]I’m trying to make the sound play without pressing any button, and the volume slider.[/font][/color]

[color=black][font=Arial]The sound’s volume should be 50 from 100% (instead of 0 from 100 as primary set)[/font][/color]

[color=black][font=Arial]I’m out of inventions. Whatever I tried, does not work. I would be very thankful for some advice.[/font][/color]
