# PreSonus Quantum Linux: investigating Quantum 2626 control for Linux audio

> PreSonus Quantum Linux documents control and audio behavior of the Quantum 2626 Thunderbolt interface while developing Linux support. Its research records channel routing and the recovered TCI protocol, with an in-house driver retained as a fallback beside builds of a separately authored upstream RFC driver. The author reports bounded playback and capture tests and unresolved stability issues.

## Requirements & limits

- **Prerequisites:** Source builds require matching Linux kernel headers, a compiler, Make, Git and curl.
- **Scope:** A Quantum 2626 Thunderbolt device is the only enabled, hardware-tested model.
- **Limits:** The driver is experimental; higher rates, physical S/PDIF and ADAT routing, and sustained stability need further testing.
- **License:** Repository-authored material is MIT licensed; upstream RFC driver bundles retain their GPL-2.0 notices.
