An open-source Linux driver has been posted for the PreSonus Quantum 2626, a high-end Thunderbolt 3 audio interface. The driver was independently developed via reverse engineering and provides playback, capture, and other features.
Imagine you're a musician and you need a special tool to make your music sound great. This tool is called an audio interface, and it helps you record and play back your music. The PreSonus Quantum 2626 is a very good audio interface, but it only works on Windows and macOS. Now, some clever people have made a special driver that lets Linux computers use this audio interface too. This is a big deal because it means Linux users can use this high-quality tool to make their music sound great.
Analysis
Background
The PreSonus Quantum 2626 is a high-end, Thunderbolt 3 based audio interface. It is a 26-input, 26-output rackmount Thunderbolt audio interface focused on delivering ultra-low latency. It's advertised as among the fastest audio interfaces available. On the downside, it's expensive by enthusiast/hobbyist standards at around $700 USD.
The Driver
A "Quantum" Linux sound driver was proposed today for upstream kernel review in providing this independently-developed audio driver successfully tested on the Quantum 2626 though other devices may end up being supported in the future. Nicholas Johnson explained in the RFC patch announcement: "This RFC series adds an ALSA PCI driver for PreSonus Quantum PCIe/Thunderbolt audio interfaces. This project is independent and is not affiliated with PreSonus or Fender. The driver provides playback, capture, raw MIDI, sample-rate control, clock-source control, XRUN reporting, and surprise-removal handling. It targets the Quantum PCI family and currently has verified support for the Quantum 2626. The implementation keeps the hardware path direct and multichannel, with the aim of being small, reviewable, and suitable for eventual upstreaming. I want to thank my best friend, Ju Ern, for lending me the machine used to develop the driver, and the Asahi Linux project for m1n1 and the tooling that made the hardware tracing and analysis possible. Only the verified 2626 device ID is matched by the driver at present. I am sending this as RFC to gather review and testing before asking for merge. I would especially appreciate feedback on ALSA integration, device enumeration, runtime PM/latency handling, and upstream expectations for the driver."
Implications
The availability of a Linux driver for the PreSonus Quantum 2626 is significant for Linux users who require high-end audio interfaces. This development makes it possible for Linux users to utilize this expensive but high-quality audio interface. The driver provides playback, capture, and other features, making it a valuable addition to the Linux audio ecosystem. The fact that the driver was independently developed via reverse engineering is also noteworthy, as it demonstrates the capabilities of the Linux community in developing high-quality drivers for complex hardware.
Key points
- PreSonus Quantum 2626 is a high-end, Thunderbolt 3 based audio interface.
- An open-source Linux driver has been posted for the PreSonus Quantum 2626.
- The driver provides playback, capture, and other features.
- The driver was independently developed via reverse engineering.
