Sound Open Firmware is one of the projects started originally by Intel but has grown into a multi-vendor initiative for open-source audio digital signal processing (DSP) firmware and development tooling for a variety of platforms under the Linux Foundation umbrella.
Sound Open Firmware 2.14 is out today as the newest feature release of SOF. Sound Open Firmware brings initial platform support for Intel Wildcat Lake “WCL”, updates to its Zephyr base OS, initial support for NXP Essential Audio Processing, power management policy updates, adding the Intel Panther Lake production key fingerprint, various topology updates, starting to remove XTOS support in favor of the Zephyr path, and initial support for Intel Nova Lake “NVL” and Nova Lake S “NVL-S” platforms. A Dolby DAX module is also added to SOF 2.14.
This isn’t the most exciting Sound Open Firmware 2.14 update in recent times with most of the changes being low-level/internal, but nice seeing the new Intel hardware support continuing quite early ahead-of-launch.
