Basically, I’m unable to use switchboard-plug-sound despite showing up in the switchboard, despite being installed, despite still working and having it's indicators. Once I click on it from the settings, It instant close itself. Due to that, I’m currently using the pulseaudio audio mixer, but it's pretty bad for me to use it instead of the default Elementary OS one. Anyway to fix that?

I suppose it's mostly due to some packages issues, but i’ve tried to reinstall it and its dependencies. I also suspect being caused by some modifications done to the tray packages to allow for the usage of indicators once again, but i’ve didn’t have any issues since now with it.
