I’m asking for specific ideas, tactful if possible

We started reciting the rosary before every mass partly in an attempt to end all the yip yap. It isn’t working. The other week I was almost yelling the ‘Hail Mary’ into the microphone and folks were treating us like we were in the background. Our choir coordinater actually came over and turned me up louder.
Father did make an announcement before mass, politely asking them to be quiet, but this side noise is still happening.
We meet in a local high school cafeteria awaiting a building, and our sound equipment is portable and not the top of the line, but we can be heard well throughout the cafeteria once folks shut up.
CCD is every 2 weeks, so those masses are packed with 400+ people.(double the normal crowd) The noise before communion from the crowd is truly irreverant. As the choir leader, I’ve been given a good suggestion of having something instrumental played while the choir receives, Would it be liturgically incorrect of me to make an announcement to invite the people to sing with us or pray quietyl in the real presence???
Father has interrupted communion in the past to tell people to pipe down. I think our music helps drown out the side conversatoins, but they don’t really go away…If the meditation song ends early, they start right back up again.
OK, rant over for now… Ideas???
