Here I'm going to show You how to remove items from sound indicator in Unity panel. Regular way is to use dconf-editor. Simply, open the app and navigate to
When You start i.e. Rhythmbox music player, it appears in interested-media-players line. You need to reset this to default value, so sound indicator will be cleaned after system reboot. Further, if You want to prevent Rhythmbox from showing in sound indicator, simply put 'rhythmbox' value in blacklisted-media-players line above (first line).
What to do if this does not work?
From some reason, this does not work for me. So I need to manually reset intersted-media-players parameter every time when logged in Ubuntu. I found another way to do this. I wrote a script for this task and put it in Startup Applications, so it runs automatically every time I logged in Ubuntu.
#! /bin/sh # # Reset interested-media-players parameter in # dconf-editor set -e gsettings reset com.canonical.indicator.sound \ interested-media-players exit 0
I called it reset_interested_media_players.sh. You can call it whatever You want. You need to make it executable.
sudo chmod +x SCRIPT
And You need to put it in Startup Applications, so it runs every time You log in Your system.
In Command space, enter the following:
sh -e /script/location/SCRIPT.sh
Change script location and SCRIPT.sh with appropriate values. That's it... It's not a big thing, but it does the job.
