Though I will have to say that I installed the one marked as
" indicator-sound-switcher - 2.1.1ubuntu0-1 (changes file) 2016-11-03 Published Xenial Python"
So I am using an older version, in Trisquel 8. I am unsure if running the version for Bionic, Cosmic, or Disco would work as well...
Maybe I will unninstall the version I have and install the other one and try?
