sof VS sof-bin

Any chance you can get some movement inside Intel on the Sound Open Firmware user-signing issue?

https://github.com/thesofproject/sof/issues/5814

here is this https://github.com/thesofproject/sof

If you search for guidance, file a bug on the SOF project on GitHub: they are very collaborative.

Hm well the kernel is at 5.18 so that should be good then, by sof are you referring to this? https://github.com/thesofproject/sof

Most firmware is either a binary blob without source, or has public freely licensed source code. The Intel Sound Open Firmware is a weird mix though, public freely licensed source code but most of the hardware can only run Intel signed firmware.

Audio not working but seems some work being done on it https://github.com/thesofproject/sof/issues/5867

https://github.com/thesofproject/sof-bin/releases had no sof-bin tarball this time, so I merged things together.

Download the following binaries and install the v1.9 driver that is included with it. https://github.com/thesofproject/sof-bin/archive/refs/heads/main.zip

Downloaded the full zip from https://github.com/thesofproject/sof-bin in personal vm, unziped, then zipped again but only the v2.0 folder.
