Outputting sound to multiple AirPlay devices fails on Tahoe, works on iOS.

How is it that I'm able to output audio from 3rd party apps (not the Music app,) to multiple Airplay speakers, HomePod and HomePod Minis simultaneously on iPadOS & iPhoneOS, however it's impossible to accomplish on Tahoe? And no, Audio Midi doesn't work, because once one AirPlay device is activated, the other one is inaccessible. it's also not possible to group the 3 together (2 minis and one Home Pod) into a single device in Home. Airfoil by Rogue Amoeba used to accomplish this task easily, but its function has been limited by Apple.
