I have a Mac mini connected to my TV, with HomePods as the speakers. Every time the mini goes to sleep, the audio connection drops, and I manually re-select the HomePods. This script fixes that by automatically re-selecting the AirPlay device. Hook it up to run at login (or wake), and the problem disappears. 100% vibe-coded with Claude.
