My current solution is Roon and Linux. I set up an old Dell PC running Ubuntu server 24.04.x LTS and a Roon server, and Raspberry PI 4 running Ubuntu 24.04.x and Roon Bridge. Avoiding broken macOS USB audio system completely 🙂

Not an issue in OBS, but having to pull it out just for a quick repro video with commentary feels overkill.
Audio MIDI Setup is all greyed up, looks like the CoreAudio driver's capabilities is minimal. #UseThePlaform

Background On April 16, 2025, Apple released a patch for a bug in CoreAudio which they said was “Actively exploited in the wild.” This flew under the radar a bit. Epsilon’s blog has a great writeup of the other bug that was presumably exploited in this chain: a bug in RPAC. The only thing out there that I am aware of about the CoreAudio side of the bug is a video by Billy Ellis (it’s great.

coreaudio自体は安定してるから、普通にルーティングとかミキサーをもっとOSベースで入れてほしいところです（ ; ; ）
