I made a Shairport server for 6 audio zones years ago on an ancient desktop computer and multiple PCI sound cards. After it died, it was hard to migrate to a single Raspberry Pi due to the USB audio cards devices scrambling on each boot (so the kitchen may become the living room, etc.).

For example, this is a rule I use to always bind my P1 (smart energy meter) at the same port: KERNEL=="ttyUSB[0-9]*", ATTRS{interface}=="P1 Converter Cable", NAME="%k", SYMLINK="USBP1Cable", GROUP="tty", MODE="0660" [1] /etc/udev/rules.d/50-ttypermissions.rules
