When we resumed Sacrament meetings on July 12th, we skipped opening and closing hymns altogether. I suggested to the bishop that I could play hymns with voices using the app, connected through the crab box to the sound system. We did that for a couple months, and then fell back to just having the hymns played on the piano or organ, with no voices. Some folks did not like to listen to the canned vocals, but I kind of liked it.
Since I run the Sacrament broadcast for those at home, I always "present" the sheet music of the hymns as they are played, so those at home can follow along. During the ordinance itself, I mute the mic and leave the sheet music up for those at home to read and ponder.
