Why not just let call sounds on and the other off? I have the call sound on so I can search for my phone and hear when someone calls me. All other sounds, like notification sounds are off. Nowadays only my parents are calling me, every other person just texts me, so this works for me, but depends on your circumstances.
I never installed Linux myself, only used it for a bit, so what do you have to do to not be a complete noob? This is only a half serious question, but what do you think you have to do, to be a proficient Linux user? This sounds a bit like when I got my master’s degree and did not have the feeling that I know anything or have learned valuable skills, but to someone with only a high school diploma I would look rather proficient.
