# Open Apollo: reconstructing Linux support for Apollo audio interfaces

> Open Apollo reconstructs Linux control of Universal Audio Apollo Thunderbolt and USB audio interfaces through hardware and driver analysis. It provides a Thunderbolt kernel driver, USB initialization stack, mixer daemon and native console, with device setup drawing needed files from the user's UAD installation.

## Requirements & limits

- **Prerequisites:** A supported Apollo interface and Linux system; the documented Thunderbolt x4 setup uses Ubuntu 24.04.
- **Prerequisites:** The user's own UAD installation supplies files needed during setup.
- **Limits:** Support is experimental; some configurations have kernel stability issues, and the rebuilt Apollo Solo USB initialization is untested on hardware in this release.
- **License:** GPL-2.0 license.
