I'd like to announce the 1.0 release of Sound Open Firmware (SOF) is available for download on git.alsa-project.org.
SOF is an open source BSD licensed audio DSP firmware that currently runs on Cadence xtensa architecture DSPs found on Intel Baytrail, Braswell and Cherrytrail based devices, however SOF is architecture and platform independent meaning it's not tightly coupled to xtensa DSPs or Intel CPUs/SoCs.
The 1.0 release supports limited playback and capture topologies alongside volume, mixing and sample format conversion.
Information about SOF can be found on the ALSA SOF wiki here :-

Development for SOF 1.1 has started which will include support for Haswell, Broadwell and Apollolake platform alongside support for SRC and more complex topologies.
