I’ve got a pi zero w doing shairport-sync https://github.com/mikebrady/shairport-sync , which makes the pi pretend to be an AirPlay receiver. I combine it with the cheapest DAC I can get (used to be Adafruit before they ditched theirs sadly, now it’s https://shop.pimoroni.com/products/audio-dac-shim-line-out ) and bam old speakers are airplay compatible. The Pi is on Trixie and everything.

It’s fantastic that it can do the airplay2 and everything without skipping a beat. Great coding from the dev of it (Mike Brady)!
