You are welcome.
Fire fighters are system relevant so I needed to help

About volume level I found that gstreamer thing also but think this is just setting 0-100 % of actual level (not sure).
So I think this approach here sounds better:
Code:
after installing alsa-utils via pkcon I was able to change the master volume/balance via cmd line like 'amixer sset Master 80%,80%'


The current code snippet I made is a one-time executer, so you would need to put into a loop. I thought it is easier to control when you want it to run. If you want it always, a systemd script on boot or cron job is good. But then it would need some more fine tuning against reliability, e.g. how to stop it or how to pause/stop the sound...
