New champion select sound (BUG?)

The new champion select makes so many sounds. This is kinda annoying, since with the old champ select i could just turn off the music, but leave the sfx on and it wouldn't bother me if i want to alt+tab to youtube or something, but i would still warn me with a sound when i need to accept or ban or whatever. But the new champ select is making so many unnecesary sounds which i can only remove by muting sfx aswell, which then results in me not getting warning when i need to ban, accept etc. Pls fix this riot
